Portable Installer Inno Setup Script

[Ozzy1911]

Form me the installer crashes after few seconds of unpacking a freearc archive.
It only hapens so if there is a compresion used, when no compresion, no crash.
No errors just Setup\Unninstal stoped working.
I tried everything that i could find in the internet even the cjstyles copyover
My system is windows 7 pro x64 run under admin rights etc etc

Any sugestions ?

Oh, and yes. The installer after unistall does not deltle the files that are being installed from the cab files

Ad this to the script :

[UninstallDelete]
Type: filesandordirs; Name: {app}
