I have a Visual Studio 2008 dll which was working fine in Windows 8.1.
The dll is called from Excel. I run Excel 2016 and have no problems in Windows 8.1.
When I upgraded the PC, with Windows 10, I installed VS2008 + SP1, installed Excel and copied over the dll.
Excel will not call it. The VB code used to call it, gets to the call line and then skips out of the class used to call the dll - as if there is something wrong with the dll call code.
What is wrong with Windows 10 in this case.
Should I just revert back to Windows 8.1?
