I can not stop CONNECT Advisor from popping-up upon starting of AECOsim Building Designer. I have tried unticking 'Launch Connect Advisor on startup' box. I have also tried 'Use my save settings' checkbox, but nothing seems to work.
This is happening due to an error in user preference settings file. You need to delete the file and when you will restart AECOsim Building Designer, it will recreate the file. Then you can make changes as per you requirement and the same will be saved.
The name of the file you need to delete is "UserSettings.sqlite". The same can be found in 'C:\Users\username\AppData\Local\Bentley\AdvisoryService\v0.8\'
