simply won't start

SOLVED

Tried opening my 2012 Simply Premium this morning and it won't load.  Keep getting the error message Sage Simply accounting 2012 has stopped working.  It says it encountered a problem and will close the program.   It worked fine up till now.  My other versions of Sage 2018 works fine.  I tried rebooting but still the same error.    Any ideas?    I share this file with the client (he does his own billing) and he doesn't have the funds to upgrade to a more recent version.   

I have since tried uninstalling and trying to reinstall the program but now that is failing as well.  I keep getting an 1628 Failed to complete installation error message.   

Update - I have since restored my computer to before the last windows 10 update and I am still getting the same issue that Simply won't load at all.  I don't understand why all these years it worked fine and suddenly won't start out of the blue.
