I rec'd a pop-up for an update a few weeks ago and it downloaded with no problem. A couple of days ago I rec'd another. Since I had no problem with the first, I clicked to download. I don't know how many hours my computer was indicating that the download
was in progress.....many. When the download was complete I couldn't open MS Starter 2010 Word or Excel. I could open the documents folder but when clicking open on any of them I got the window that said that the program needed to open was not installed on
my computer. I read most of the posts here and tried a number of things, and finally went to the control panel and on the list of programs I found Microsoft Office 2010 showing installed 9/11/2013 and Microsoft Click-To-Run installed 7/19/2012 but the only
option was to uninstall, not change and repair. But the Microsoft Office Starter 2010-English, installed 7/19/2012, Version 14.0.5139.5005, had the option to uninstall or change.
I clicked "change" and the option to repair Microsoft Click-To-Run. At some point (I can't recall every word of the process) it gave the option to download Microsoft Word Starter. I did, and by whatever miracle, the problem was fixed. After the downloading
it did give a message about some difficulty and asked if I wanted to run it in "safe mode." I declined - no problems.
