Still crashs at the same two described points.
Since Windows 8, UAC is more integrated. Turning off UAC in system settings don't turn off this feature completly, you have to go in regestry in set EnableLUA to 0. Without UAC, Metro Apps wont work anymore.
So I turned off UAC, set EnableLUA to 0, as recommended, I rebooted my PC and started DGIndexNV with administrator privilegs. More rights are not possible ^^ But it still crash on desktop and D:\Sonstiges
I think the typical DGIndexNV user is able to install runtimes and know why
