Hey guys, hope you can help me out.

Im trying to run Rheingold for several hours the last days but didn't get it work...
But from the beginning:

Running Windows 7 Prof via Parallels on an MacBook Pro.
Here I have NCS Expert, E-Sys and INPA working well.

I tried several Rheingold versions and always got/get the Error when starting the ISTAGUI.exe: 'Failed to start ISTA. Please make sure your ISTA configuration ist valid. In doubt reset any non standard ISTA configuration and reinstall ISTA.'

--> I solved this problem 50% I installed several vcredist's and now it's working a bit better. Curious is, when I want to start ISTAGUI.exe from the Folder C:/Rheingold this message is coming still anytime.
But when I start the INSTAGUI.exe from my shared parallels Folder this Error is not coming.

But then there is coming a new Error: 'The session can only be started if a minimum of 2000mb free disk capacity is available. You only have -1mb free.'


The versions I tried are standalone. Only with a german SQLiteDBs.
I really don't know how to proceed. Thankfull for any help out.

ISTA Versions I tried:4.09.33, 4.13.14

Thanks in advance
Cheers
