I was working on a project using Excel 2010 where I had to copy entire worksheets from one workbook to another. I was doing this through some vba code. When I attempted to save the target file, I would get an error. The error message was vba 1004 — with a message of:
Errors were detected while saving ‘c:\filefolder\filename.xlsx’. Microsoft Excel may be able to save the file by removing or repairing some features.
It took quite a bit of research to figure out what was going on. Luckily, I stumbled onto this KB from Microsoft. It appears this is caused by a known bug. You cannot save a workbook that contains an image that was copied from another workbook in Excel 2010 – unless a patch has been applied to Excel. Here is the link to the KB:
Hope this saves someone some time.
