'The Bootstrapper has stopped working'. I have tried many suggested solutions on the NET to no avail. One hint had me looking at Services, where I found that SCHEDULE 'Failed to read description, Error code 193'. Google did not seem to know how to fix that in Win10 - except in relation to disabled Print Spooler - but my Print Spooler service is started. Error code 193 might be irrelevant to installing MSOffice 2013, but then, it MIGHT be relevant.
