Had trouble with my XP computer...motherboard was replaced. Programs were saved, but not without issues. I could not define colors for a gradient screen and thought that the program needed reloading. When I went to un-install the previous version, it requested that I deactivate it. I assumed that since it would be the same program, just reloaded, I did not deactivate and am now wondering if this is the reason I cannot re-install. I took photos of 2 of the error messages:
Below is the first "error" ...
This error resulted "after" I tried what was suggested...restarting and trying again...
