Fixing Photo Impact 6 through 11 on Vista and Windows 7

Installed PhotoImpact 10 on Windows 7.
Got same "Failed to update the system registry. Please try using regedit." error message
after it was installed when every time I wanted to use PhotoImpact.

Did what Buckeroni wrote; ticked > Run this program as an administrator.
It worked but with the now new annoying Windows 7 User Account Control warning allowing the program to run.?!

To stop this go back and untick > Run this program as administrator.
PhotoImpact should now open with no Windows error or warning messages at all. grin

So far in PhotoImpact, I notice one feature not working is "Open Recent Files" in the File menu.
