Random Crash of NSIS-Installer

[LSI_Riedel]

Dear All,

we have a problem with our Installscript and I hope someone can help me.
On Win Vista/7 32/64 the Installer randomly crashes.
It seems the problem is our Photoshop Section. If we uncheck this section all seems ok.

This is the error. Also see the attached screenshot.

Is there any error in our syntax for this section or does anyone have similar problems?

Thanks for help
