i had the same problem and managed to solve it on my computer. before i go any further i strongly advise you to consider alternative options given that this may screw up your machine's settings. 0) off the bat i went with the basics. trying to uninstall over Add/Remove Programs. this of course didn't work. 1) next step. i deleted the Paint.net folder in the Programs directory and tried a reinstall. one step closer, but still got an error during execution of the Installer file. 2) just to make sure there was no discrepancy between the .NET frameworks currently installed on my machine (different language packs for different frameworks screw up the system) i first uninstalled, then reinstalled {.net FW 1.1, 2.0, 3.0 and 3.5 beta}english (overkill. i know. ) - this did not solve the problem in my case but it cleared my concience. 3) openened up START --> Run... --> regedit and went over the registry with a flamethrower and some holy water ie : i did a search for any entry, key or value with the word "paint" in it. any that i found which were related to paint.net i deleted . if there were any default keys in the same folder that were not directly related i left them alone (unless they spit at me or disrespected my lineage). (with the F3 button you skip to the next found entry. saves some time.) 4) - i opened the freeware prog CCleaner(http://www.ccleaner.com) - on the registry tab selected "scan for issues" - then selected "fix all" - on the "Cleaner" tab ran it to clean up any trash left behind ................ after that i installed Paint.Net 3.10 . no problems during install or operation. once again. if you do this you are messing with the registry. this can do serious damage so proceed with caution. - G
