Community v4.0.5 does not open with either:
- Double-click on the TPR file
- Right-click > Open with TestWise
As an experiment, I also installed the Professional v.4.0.6. I have the same problems with that.
It would be most helpful if some other community members would post if they are able/not able to open a file with double-click or right-click on the TPR file.
