I forgot to ask you what version of Windows you have? But before you perform anything, let us check to make sure your Windows files are Not corrupt.
With no other programs running, open Command Prompt with Administrator rights. If you have Windows 10, Right-Click your start button and click RUN. If you have Windows 7, Left-Click your Start button and Click Run.
Under the box type in CMD and press Enter.
When the DOS box opens up, type sfc /scannow and press Enter
Let this process continue. It could take up to 20 min to complete.
If Windows found problems and fixed it, reboot your system.
If it did not find any errors, then you can continue.
***
To get to the properties of VP, right-click the Icon and select Open File Location and look for Vegas.exe or something similar.
You should then be able to follow the instructions previously mentioned about going to compatibility tab.
Good Luck.
