My Projects' Long Filenames??? Error when I install through my Installshield program.

There is a project in VB, made to perform some file
unifying tasks.

I have created the installer program through installshield 5.1.
The thing works perfectly fine when using the 8.3 format (short
filenames). But when I try to install it into a long filename
directory like c:\Program Files\... then the program does not work
and it gives some problems because a few files are not found.

I have used the function: LongPathToShortPath() to convert
the long filenames into short ones and even the autoexec
entry is short as well. I have checked the registry entries
and they are short as well.
Still the program does notwork correctly.



A problem stays like a challenge till
I find the solution to it.
