How to choose Visual Studio or TcXaeShell export from CPS

[merinoTuu]

Hello,

I have a question regarding the export procedure with CPS. How can I change my default TwinCAT development tool? I remember that the first time that I did an export, CPS asked me to choose between TcXaeShell and VisualStudio, but now I cannot choose anymore. I tried to reinstall CPS, also I tried to save the PLC project with TcXaeShell but it is not working. Does any user have an idea how could I change this setting? 

Thank you.

2. Select the solution in the Solution Explorer and explicitly save the solution (not Save All):
   
3. Now the SLN file is updated and Control plus Studio / OES will open it with this version:
