Is there a better way to setup the MSVC environment?

This has been a problem for a long time now, with several reports in the forum and here.

Running the vcvars* batch file to retrieve the enviroment seems to break easily.

As the batch file (if I understand correctly) simply queries registry values, I wonder if Creator could query these values itself. This should not only be faster but also looks less suspicious to the Anti-Virus software out there.

Sounds too easy - what am I missing?
