--- Comment #5 from Anastasius Focht focht@gmx.net --- Hello jre,
drive 'C:' is a fallback choice, yes (the app states it in the message).
From logical point of view it doesn't make sense to execute a USB/portable
installation directly to the main hard-drive since this violates Windows design guidelines for software installations. Instead I would expect the installer to fall back to standard MSI based setup routine.
Please test with a real Windows and force the USB portable installer part to drive "C:" (instead of the USB stick).
If it really puts a fully working portable installation on "C:", I'd de-duplicate the bug again, tracking this problem.
Regards
