Lost Corel X5 during system restore Noww cannt re install it

[CorelArtist]

I went through a system restore yesterday. Im not sure how maybe somebody scheduled it without me knowing. Anyway I have tried and tried to reinstall Paint Shop Pro X5 but something pops up saying "Your system has not been modified. To complete istallation another time, please run setup again." Can anyone help me?

If the application is still listed in Control Panel...Programs and Features, uninstall it.

If not, use the MS Fix It tool:

Also see Corel's instructions for manually uninstalling PSPX5:

This isnt working either. I have tried everything.

Can you not undo the system restore? Usually there's an option to do so.
