    Qt Creator 4.7.0
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?
