When I save an excel with some data from a Creo 3 mechanism analysis, the extension is .xls
But when I open this file in Ms Excel, the program starts with the following warning:
The file will open after selecting "Yes", but appearantly the file is in a wrong format. When I manually change the extension to .xlsx
the problem is solved. But why do I have to do this..?This thread is inactive and closed by the PTC Community Management Team.
