Define Problem and FIx for standalone software dotNEtFx40 that has stopped working - open to bidding

I have a Standalone software and database setup which I have been selling to my customers since 2011. It is delivered on a CD with the data (excel spreadsheet, the dotNEtFx40_full_x86_x64 and Windows installer 3_1)

in the last few days a few of the clients have contacted me and said the interface doesn't work anymore the tabs are greyed out. I suspect it is due to a Microsoft Update early this week, but I dont know what caused it.

I want someone who has a knowledge of .net, excel, to download the program and tell me what the problem and fix is.

I can provide a link to dropbox for all the files that are sent out to customers for the program on the CD - it is around 64mb

Skills: .NET, C# Programming, Database Programming, Software Architecture, Windows Desktop
