Trouble with drive letters fixed?

Hey!
Think Native access looks really nice.
Was frustrated though, just about every app (Massive, FM8, Absynth etc) failed, and it also corrupted service centerand komplete 10 downloader.
I also tried the ISO-files but got error there to package not found etc.
One error caught my attention, it said wrong drive E:
I looked in my system when I mounted the ISO, and it wasn't E:
So after mounting the ISO I changed drive letter to E: (windows disk management) and it worked.
Hope this helps someone however the installation should not rely on hard coded drive letters, it's asking for problems.
Running Windows 10 pro 64bits AU, 32RAM I7.

 

Note there's still problem with installing from Native Access, but it works from the ISOS (they don't get deleted when failed it seems.)

 

Bummers, only worked one time with reaktor!
Edit!
It works when I get an error with wrong drive letter.
