PowerDesigner 16.1 Repair

After installing an EBF, do you quite often find PowerDesigner does not work properly?  A very common occurrence I have is the receipt of the following message (multiple times, I might add):

After Googling this error and trying some of the suggested fixes, I finally called PD support and this is what worked:

1. Close PD.
2. Start - Control Panel
3. Programs and Features
4. Right-click Sybase PowerDesigner ...
5. Click "Change"
6. Click "Repair"
7. Click "Next"
8. Click "Finish"
9. Open PD - hopefully it works.
10. If not fixed, uninstall PD, reinstall base PD and last EBF (they are cumulative.)
