Okay, I went back to the distribution disk, and installed dpp version 1.6.1. However, when it got to the end of the installation, it asked if I wanted to restart. I said no, as I had an email open, and then the installer gave me an "installation failed" message. However, the program will run. Unfortunately, I cannot upgrade to a newer version, nor can I uninstall version 1.6.1. When I try t run an upgrade, it begins to extract files, and then says, > You cannot install Digital Photo Professional on this computer. Verify whether the required environment for use has been satisfied. Cancel installation. If I try to uninstall version 1.6.1 through the wine uninstaller, nothing at all happens. Thoughts?
