The RENI Floppy Disks

The complete RENI System is shipped on several floppy disks, numbered RENI1, RENI2, etc. (the number of disks supplied depends on the disk format and storage capacity). The floppy disks contain the RENI program executable files and all required data files. For any Installation or Update, you must run the RENI Set-up Program RESETUP! Please never try to copy the contents of the floppy disks manually to your hard disk because the files on the floppy disks are compressed!

The RENI Installation / Update Program RESETUP

The first RENI floppy disk (named RENI1) always contains the installation and set-up program called RESETUP. During Installation, this program creates the required directories on your hard disk and then automatically copies all files to the appropriate directories and customizes the RENI program. If you would like to Update an exiting version of RENI use RESETUP in "Update mode" to copy only the necessary files from the floppy disks to your hard disk.

If the RENI Set-up Program RESETUP detects any errors during the installation or update process, a corresponding message is displayed and program execution is terminated. Please refer to the section "Possible Error Messages During Installation/Update" for a more detailed explanation of the possible source of the error and its recovery.

Where to go next?

  • RENI Installation
    If you would like to INSTALL a new version of RENI, follow the instructions given in the section " Installation of RENI"

  • RENI Update
    If you would like to UPDATE an existing version of RENI to the newest release, follow the instructions given in the section "Update of RENI"
Installation of RENI

1 Start the Installation Procedure

Insert the disk labelled RENI1 into your floppy disk drive.

  • If you are using drive A: type at the DOS prompt:
      A:RESETUP A:

  • If you are using drive B: type at the DOS prompt:
      B:RESETUP B:

You will then be presented with the RENI logo screen. Press any key to take down this screen and to continue the installation. RESETUP will display as a next step some information about your current installation (e.g. the name of your company, the serial number of your RENI program, etc.). Press again any key to continue.


2 Assign the Hard Disk Drive

The next screen you see will show you a list of available hard disks on your computer, on which you may want to install RENI (disks, which are part of your network, are marked with an asterisk). Now you can specify the hard disk for your RENI installation (as a default the first disk detected is shown, e.g. C: on an IBM type computer).

If you accept the default value, press ENTER and go on to step 3.

If you want to change the drive, type in a new drive letter and press ENTER when finished.


3 Assign RENI Directories

Next you will see a screen with the proposed RENI directory names for the program files, manuscript files, lexicon files, help files, etc. In most cases you should accept the default values shown on the screen. To do this, simply press ENTER.

If you accept the default value, go to step 4.

If you like to change any of the directory names, use your TAB key to move to the next field or SHIFT+TAB keys to move to the previous field and type in your new directory names. When finished, press ENTER to accept the values.


4 Check Free Disk Space

After you have assigned or accepted the RENI directories, the program checks for the available space on your specified disk drive. If not enough free space is found, you will get an error message and need to either select a different disk drive (if available) or delete some files from your current disk to make room for RENI.

If no error message is displayed, the RENI set-up program creates all directories and then copies all files from the floppy disk RENI1 into the appropriate directories on your hard disk. Once this is done, you will be prompted to enter the next floppy disk to continue installation.


5 Insert Additional Disks

Insert Disk labelled RENI2 in your floppy disk drive. The set-up program then copies all files from this diskette to the appropriate directories. Continue with other diskettes (RENI3, RENI4, etc.) if applicable.


6 Modify the AUTOEXEC.BAT File

After all files have been successfully copied from the diskettes, you will be asked if you would like to modify your AUTOEXEC.BAT file.

Modifying your AUTOEXEC.BAT file simply means adding some information to allow you to run RENI from any DOS prompt by typing in "RENI". If you do not modify AUTOEXEC.BAT, you will need to manually switch over to the RENI directory every time before running the program.

It is recommended that you answer "YES": To do so, enter the drive letter of your boot hard disk drive or accept the letter given by the program (C: on IBM-compatible machines). Then press the ENTER key. If you decide not to modify your AUTOEXEC.BAT file, press the ESC key.

After answering "YES" to this prompt, you will be notified that you must re-boot your computer in order for the changes to the AUTOEXEC.BAT file to take effect (on IBM-compatible computers do this by pressing the "CTRL" + "ALT" + "DEL" keys simultaneously).

Once your installation is finished and your computer is re-booted you can begin using RENI by typing the following command at the DOS prompt:

    C:\>RENI
If you have decided NOT to modify your AUTOEXEC.BAT file, you always have move to the RENI program directory before starting RENI. You can also modify the AUTOEXEC.BAT file later, by adding the following information to the file:

Add the name of the RENI program directory (e.g. C:\RENI) to your PATH definition. This line may then look something like this:

    PATH=C:\;C:\DOS; ...;C:\RENI
Add a new line to your AUTOEXEC.BAT file:
    SET RENI=C:\RENI
which specifies again the RENI program directory (C:\RENI in this example). This statement is necessary to tell the RENI program where it can find the required data files on the disk.

Any time you modify the AUTOEXEC.BAT file, you will need to re-boot your computer in order for the changes to take effect.


7 Out of Environment Space error

If you eventually get a DOS error message during boot time that says you are "out of environment space", you may need to increase the space DOS reserves for the environment parameters. Ask your system manager and/or consult the DOS manual for the required changes. For DOS versions 3.3, 4.01, 5.0 or 6.0, for instance, you may need to add (or modify) the following line in your CONFIG.SYS file:

    SHELL=C:\COMMAND.COM /p/e:640
The parameter "/e:640" will reserve 640 bytes of memory for environment parameters.

Update of RENI

1 Prerequisites to perform an Update of RENI

In order to perform an update of RENI, the installation program RESETUP needs some information about your previous RENI installation:

  • You have to move to your RENI root directory (e.g. to "C:\RENI") before starting the update procedure.
OR
  • Your RENI root directory has to be defined in the DOS environment. This is the case, if your AUTOEXEC.BAT file contains the line "SET RENI=C:\RENI" (assuming that the RENI root directory is "C:\RENI". In order to check the current situation, type the command "SET" at the DOS prompt and examine the listing. If you cannot find a line "SET RENI=..." move to your RENI root directory (e.g by typing "CD \RENI") before continuing with the next step.

2 Start the Update Procedure

Insert the disk labelled RENI1 into your floppy disk drive.

  • If you are using drive A: type at the DOS prompt:
      A:RESETUP A: /U

  • If you are using drive B: type at the DOS prompt:
      B:RESETUP B: /U

(If you are using any other floppy disk drive, substitute its drive letter for "B:" in the example above).

The additional parameter "/U" is necessary to notify the RESETUP program that you want to perform an Update rather than a new installation.

You will then be presented with the RENI logo screen. Press any key to take down this screen and to continue the installation.


3 Check for Messages

The installation/update program might display an error message in one of the following situations:

  • if it could not detect your older RENI installation

  • if an update is not possible because your installed RENI version is too old

  • if the shipped RENI version has not been prepared for update

If an error occurs at this point, the update process is terminated. Please refer to the section "Possible Error Messages During Installation/Update" for a more detailed explanation of the possible source of the error and its recovery.

If no error has been detected, RESETUP will display as a next step some information about your current installation (e.g. the name of your company, the serial number of your RENI program, etc.). Press again any key to continue.

It then starts to copy the required files from the floppy disk RENI1 into the appropriate directories on your hard disk. Once this is done, you will be prompted to enter the next floppy disk to continue installation.


4 Insert Additional Disks

Insert Disk labelled RENI2 in your floppy disk drive. The set-up program then copies all files from this diskette to the appropriate directories. Continue with other diskettes (RENI3, RENI4, etc.) if applicable.

Using RENI

To run the RENI program, simply type

    C:\RENI
at the DOS prompt. If your AUTOEXEC.BAT file was not modified during program installation (see the installation chapter) you have first to move to the RENI program directory before you can run the program.


Installing a new License

In order to use RENI, you need to have a License which is valid for a limited period of time only. During the Installation and/or Update process this license will be installed automatically.

The RENI SetUp program has two options to install only the License without altering any other data (in both cases you need to move to the RENI directory (usually C:\RENI) first):

  • You can use the "/LF" option to install the license from the file RENIS.LIC: at the DOS prompt type

      RESETUP /LF

    The SetUp program reads all data from the license file and updates your system.

  • With the second option "/LM" you can install a license for a specific RENI module: at the DOS prompt type

      RESETUP /LM

    The program asks then for a specific "License String", which can be obtained from Fraunhofer ITA.

Possible Error Messages during Installation/Update

This section summarizes all possible error messages, which may occur during the installation or update procedure of RENI. If possible, information to recover from such a situation is also presented. The error messages are listed in alphabetically order.

Error 1 in Installation data file
This error occurs, if the content of the Installation Data File RENIS.DAT has been modified. The set-up program is not able to continue the installation/update.

Error 2 in Installation data file
This error usually occurs, if the RENI Security Module has not been attached to your computer. Check this situation and perform the installation or update again.

Error in Information file
A section in the Information File RENIINFO.DAT, describing its content, is missing in that file. The set-up program is not able to continue the installation/update.

Floppy drive cannot be used for installation
This error message may occur if you try to install RENI on a floppy disk. Please select one of your computer hard disks for the installation.

Information file not found
All data needed to perform either an installation or an update of RENI are contained in the so-called "Information File", named RENIINFO.DAT. This error message occurs, if the set-up program could not find this file on the installation floppy disk. Please check if you are using the right disk (RENI1).

Installation data file not found
The set-up program needs some data, which are store in the so-called "Installation Data File", named RENIS.DAT. This error message occurs, if the set-up program could not find this file on the installation floppy disk. Please check if you are using the right disk (RENI1).

No data for INSTALLATION in Information file
The user has specified to perform a new installation of RENI but the Information File RENIINFO.DAT does not contain the required data for an installation. Please run the set-up program again and perform an update by specifying the "/U" parameter on the command line.

No data for UPDATE in Information file
The user has specified to perform an update to a newer version of RENI but the Information File RENIINFO.DAT does not contain the required data for an update. Please run the set-up program again and perform a new installation.

Not enough space on disk X: only nnnn bytes free. RENI needs about Y.0 MB
This error message occurs, if the set-up program has detected not enough free space on your hard disk (X: refers to the drive letter of the disk specified for installation; the program also reports the amount of free space on that disk in bytes). Select a different hard disk drive for installation or delete some files from your current disk.

RENI Update not possible: existing version must be 1.18 or higher
This error message occurs if you try to perform an update, but the existing RENI version is older than version 1.18. Perform a complete new RENI installation.

RENI Update not possible: no old version of RENI found on system
This error message occurs if you try to perform an update, but the set-up program was not able to find an older version of RENI on your system. Either move to the directory, in which your old RENI version is installed, or specify this directory with the DOS SET command, e.g. SET RENI=C:\RENI.

Wrong information in Installation data file
This error message may occur during update, if the set-up program detects incompatible information about your previous RENI installation in the Installation Data File RENIS.DAT. Please check, if the Serial Numbers of your previous installation match the one on your installation disks.

YOUR SYSTEM DATE IS WRONG ! Adjust your computer clock to the right time and try the installation again
The set-up program has detected that your computer system date has been set to a date, which is prior to the preparation of the installation disk. Please adjust your computer clock to the right date and time and run the set-up program again.
