Uninstall the program then browse to “C:Program Files”. Try reinstalling it again and see if the folder was also deleted. Some of the corrupted files might still be in there and installing it back will not delete these files and will only allow the program to still reuse them instead of replacing them with the default files from the installer. Because there are times uninstalling applications doesn’t remove the folder where they are installed and this is very common. If you already reinstalled the product and still nothing happened, you should check if after uninstalling it its installation folder was also removed. I think the reason for having this error is because of its version. PowerIso Virtual Drive prompting for installation error
