Macro in Excel not working after update

I am using an Excel 2013 sheet to create invoices. It is powered by macro’s a lot. After the latest Office updates the Excel sheet did not work like it use to. It reported unclear errors.

After some searching on the internet I found the solution to this situation. Just search for file MSForms.exd, which shall be located in temporary folder C:\Users\user.name\AppData\Local\Temp\Excel8.0\ and delete MSForms.exd. The file will be rebuild during the next Excel 2013 launch, and all VBA macros will work.

It worked and so did my Invoice sheet.
