Thank you for your help, mate
modifype.exe reports 'Could not open file', for each of the files in the 'for' loop.
I always make my silent switchless installers by myself manually and so i find it strange that the headers are borked, but they must be, then...
They are all 7z SFX installers and i'm using Oleg Scherbakov's modified version of the 7z SFX module for installers, as it features some extra functionality like e.g. running msi's directly and hiding the console window with batchfiles etc.
Anyway, it's not really a problem for me, since i'm normally always just using the "RunOnceEx from CD" approach for installing my apps, but i where just momentarilly thinking about if i should switch over to using the HFGUIRUNONCE folder instead, and then when i tried it out, then i though that i had found a bug and which i then wanted to report...
Again, thanks alot for your help, mate
