I recently upgraded my operating system from Win Vista Home Premium to Win 7 Home Premium. Everything works fine, except for Comodo. I tried to reinstall, and I keep getting the same message:
Source file is corrupt. Error 4294967295
I have tried downloading the file from the Comodo site, and tried from an official mirror at MajorGeeks. Even downloaded on a different computer, and tried to install from a flash drive. All gave the same message. Any ideas on what to try next?
Security software almost never survives through OS upgrades because they install and initialize drivers specifically for that edition of the OS.
I would try running the uninstaller, then run the comodo cleaning .bat file. If the uninstaller is throwing the error then the windows install cache is corrupted and probably not even forced uninstall via revo will work.
If all that fails then your looking at backing up your data, and doing a clean install instead of upgrade.
