I went back to Excel 2003 from 2010.

I need to open an xlsm file in 2003. I was prompted to download the "FileFormatConverters.exe". When I tried to install, it requested that I remove the previous version. I found Microsoft File Converter Pack in Add/Remove programs and uninstalled it, but it still gives me the following popup when I try to install FileFormatConverters.exe:

"Another version of this product is already installed. Installation of this version cannot continue. To configure or remove the existing verion of this product, us Add/Remove Programs on the Control Panel."



Any advice? Thanks!

Hi cryjoh,

Care to share the solution?

Sorry to waste people's time with this post.

In "Add/Remove Programs", I did indeed remove a file I believe was called something like Microsoft Office Compatibility Pack.

However, I did not have a check in the box "Show Updates" in Add/Remove Programs. When I put a check in there, sure enough, there was an update for MS Office 2007 compatibility. Once I removed that, I was then able to install the latest update "FileFormatConverters.exe".

Now I can open xlsm, xlsx, etc., in Excel 2003.
