Okay, I have an oddly specific situation: I made a bunch of macros and Visual Basic code in an Excel 2003 Spreadsheet running on Windows 7. The product has been working perfectly for one and a half years and the client was satisfied. Recently, a new employee has been employed and they prefer to work on a Windows 10 running computer. Said computer has MS Excel 2003 and when they open the same Spreadsheet it works fine. Here's the twist: after that the computer working on Windows 7 cannot open the same product (Error:After allowing macros on startup the file crashes and needs to be either closed or troubleshooted online). The question is: is there a difference between how Windows 10 reacts to the Spreadsheet and how Windows 7 reacts to the Spreadsheet?
