I had so much trouble in installing Qtouch Studio.
I tried all software variants , including AVR QTouch Studio, including Visual Studio shell 2008 SP1 and .NET 3.5 SP1.
The program Qtouch Studio fails to start. Error given: "Microsoft appEnv environment Cannot find one or more components". I have installed manually all the software requirements given in the Qtouch release note 4.3.1.
I mention that the error changed from Microsoft Visual Studio 2010 Shell Isolated Cannot find one or more components into what is it now.
I now that the problem is related mostly to Microsoft , but I hope someone has a clue how to fix it.
