Excel Document - incorrect extension

peggiegreg used Ask the Experts™
Hi Experts,

I have 2 PC's, both running office 2003. both have the 2007 compatibility pack installed. both are identical in setup.

1 PC wont open .xlsx files, I know that the file extension is suppose to point at Microsoft Open XML converter but I don't know where I am browsing to find it.

for example excel is located in : C:\Program Files (x86)\Microsoft Office

The conversion should be automatic. Try re-installing the converter on the problem PC
I tried re-installing It several times, even re-installed office and got no luck.

in the end I managed to resolve the issue by doing the following:

going to Control Panel\Programs\Default Programs\Set Associations
and then selecting .xlsx and changing the default program to C:\Program Files (x86)\Microsoft Office\Office12 and select the Moc file. which is the : microsoft open XML converter

worked fine!


I found the solution in the end.
