I get this installationerror when attempting to install Dragon 15 to my laptop where it installed without problems before. Lunis responded to me on KB forum. Disabling UAC did not help.
If there are remnants left over from the previous install, this can be interfering with your reinstall.
Before you attempt to reinstall DPI 15, and if you don't already have it, download and run the DPI15cleaner (DPI15Cleaner.exe). Then try reinstalling. Regardless, running the DPI15cleaner (DPI15Cleaner.exe) will clear out anything that might be in the registry or left over from a previous install. It's always a good place to start when you run into these types of problems.
Let us know if this works.Chucker2017-01-12 07:22:58
