Please help / advise

I think your problem may be switching between the WCG-branded and the plain vanilla BOINC-branded versions of BOINC (or vice versa).

Either: try to stick with the same installer branding - WCG or BOINC.

Or: try to uninstall the old version you're using, and install the new one 'clean'. It won't matter - either version can be used to run all of your current and future projects.

If your current version has been damaged by the failed upgrade, and either won't run or won't uninstall, try re-installing the version you were running before, ideally from your previous download file (it should offer to 'repair' the current installation - allow it to do that). Then, you should be able to make progress again.

Try using https://support.microsoft.com/en-us/help/17588/windows-fix-problems-that-block-programs-being-installed-or-removed to get rid of the old installer.
