Customized Installations and Troubleshooting
============================================



This file contains information for users who would like to know more 
about the way ISYS installs itself. 



User-level information is provided in the ReadMe file that installs
as a program manager icon.




1. DOS & Windows versions
-------------------------
If you plan to run both versions of ISYS, we would recommend that you install
both versions in the one directory, as they are designed to work together
that way. You can, however, install them in seperate directories if you
choose.



2. Common Problem
-----------------
A common problem that prevents ISYS from running correctly is having older
versions of critical VBX or DLL files that already exist in your Windows
directory.

ISYS installs, at Microsoft's recommendation, its VBXs and DLLs into the
Windows System directory. If you find that ISYS behaves unpredictably or
strange error messages appear, check your Windows directory for any VBX or
DLL files that also appear in your Windows\System directory. If any such
duplication exists, delete or rename the copies that reside in your Windows
directory. This should not affect any existing software, as VBX files tend to
be upwards and downwards compatible.

A program, VBXDUPE.EXE, has been provided on the original install disk
that will scan your Windows and Windows\System directories, as well as all
the directories on your PATH for duplicate DLLs or VBXs.



3. Installed Files
------------------
ISYS installs files into two different locations. In your ISYS product
directory, it will place:

        IQW.EXE                    The query program
        IDBW.EXE                   The utilities/maintenance program
        ISYSREAD.ME                Additional documentation
        ISYSWORD.DOT               Word for Windows macro
        ISYS.CWD                   Default common word list
        ISYS.KEY                   Licensing information


In the Windows System directory, it will place the files:

        ISYSDLL.DLL              The ISYS retrieval engine
        VBRUN200.DLL             Microsoft VB runtime DLL 
        IMVB1.VBX               
        IMGBMP.DIL              
        IMGGIF.DIL              
        IMGPCX.DIL              
        IMGTIFF.DIL             
        IMGWMF.DIL                
        IMGEPSF.DIL               
        IMGTGA.DIL                
        CMDIAGLOG.VBX
        INSTSCRL.VBX
        SPIN.VBX
        THREED.VBX
        SS3D2.VBX
        SS3D3.VBX
        MHTR200.VBX
        MHIT200.VBX
        MH3B200.VBX
        MHCM200.VBX
        MHRUN200.DLL
        BIGBAR.VBX
        CSFORM.VBX

You may, if you choose, relocate these files to another directory following
installation. 



4. Troubleshooting the Install
------------------------------

If the SETUP program does not perform as you require due to the configuration
of Windows or your network, you may install the software manually.

This is done by using the EXPAND program shipped with Windows 3.1 to manually
copy and decompress the files VBRUN200.DLL, SETUPKIT.DLL and SETUP1.EXE from
the install disk. 

You can then run SETUP1 directly to complete the installation process.


Installation problems often occur if users have two conflicting versions of
LZEXPAND.DLL or VER.DLL in their Windows and Windows\System directories.
Usually, removing the older duplicate will eliminate the problem.
