INNO Setup Problem - App will not launch

[Letsgetcoding]

Hey guys,

So heres what happening, after I install my program on a machine with Windows XP, when I try to launch the application from the shortcut, or even going into the program folder in program files itself, I get an error noise, and then nothing.

Heres what iv noted:
If I place a non compiled copy of my app on my desktop, it will run.
If I rename the app in program files, it will run.
On windows 7 it installs and runs fine.
It does this error on both Windows XP machines iv tried it on.

I have tried changing the GUID in INNO, iv changed the folder names, and iv changed the application name, yet it still does an error noise, and then nothing.

Any ideas?

Thanks!
Jessee

Changing things in the GUID won't change this behaviour. Unfortunately this is a Windows -issue. Something in your OS is causing this issue, but I really can't tell what that issue is...
