My VB program works great in 2013. When I installed 2014 it stopped working. I found out that it is the .NET 4.5 framework that is causing the problem since 2013 won't run it without crashing unless I uninstall 4.5. While it was running I noticed some of this in the Immediate Window. Should I be worried about these. I'm taking portions of the program out so I can track down what is causing the problem. The only thing the program is doing now is loading a 3 Excel Spreadsheets, creating a new drawing, reading data from Excel into variables that I'm not doing anything with, and saving the drawing.
