v10.x IDE crash when changing file properties

I'm new. With this out of the way, read on...

Program in question is InstallShield X Professional - AdminStudio Edition

(SP1 included). AdminStudio is v6.0 (exact version number is 6.0.0.122)

Here's what I've done (step by step):

1. pointed to an .MSI file

2. started IS Editor from context menu

3. selected "Installation Designer" tab

4. selected "Setup Design"

5. selected a feature from tree

6. selected a component from tree

7. selected file

8. called property windows for a selected component

9. changed "Vital" and "Self register" flags

10. selected "Apply"

At this point, IS Editor crashed and displayed a report window.

So far I've managed to find only a hotfix under article Q111233 ,URL is

However, this hotfix applies only to IS Editor 10.5x and I have only

version 10.1.0.238.

So far, I was unable to find any articles regarding this problem for version

10.x of InstallShield Editor.

Could anyone please point me to a right hotfix ?

PS: I did manage to change file properties from "Direct Editor" without

crashing the IDE except for the "Self Register" attribute. If there's a

way around a bug for this one too, please let me know.

PPS: As suggested in help, I provided a clean windows environment

for the adminstudio package by putting the whole thing inside

emulator (VMWare). I keep backup of the whole emulated system

so I have a clean start every time. I mention this since it may

have something to do with the crash ...
