First I must thank DC3 for his help on the problem that spawned this post,
I have simplified my problem that I originally posted about. To solve the main problem, I had to download and install Office 2007, to be more precise I had my IT guy do it. Unfortunately he left Office 2013 installed, So now my app needs Excel,to run and sees Office.2013 first,( which is corrupt), and without intervention will not open.So I am asking for your help in deleting Office.2013. It looks like I need to use a removal tool which MS is happy to provide, but I am afraid it will un-install Office 2007 also..
Normally I would have no problem with that, but I do not have Product Key which I am sure would be needed for re-installation of Office 2007.Is it possible to un-install Office.2013 without touching Office 2007? I realize I may have to update and repair Office 2007 after dumping Office 2013. Your help will be truly appreciated. Thanks.
