Installing HANA Studio fails to install MS C/C++

Hi,

when installing LastWS (currently in week 33) of HANA Studio, I get an error in the first phase. Please see attached image for the log from first error to end. I am getting the same error when installing weekstone 31.

I corrected the Java path, so it displays correctly in the second screen of the installer.

I also checked TEMP and TMP environment variables. They point to %USERPROFILE%/AppData/Temp, which was read-only. I made the folder writable without effect.

What else must be done?

Thanks a lot,
