Fix – Office XP opening DOCX, XLSX files – Compatability pack broken
If you’re like me, you discovered that the compatability pack for Office XP broke sometime earlier this year. You can’t open DOCX or XLSX files from outlook. You get a strange bunch of errors when opening DOCX and XLSX files and end up opening a file with a strange name in the temporary directory when it works.
You have 3 choices:
- upgrade to Office 2007 or 2010;
- roll back update kb981715; or
- find and install a prior version of mso.dll (not recommended).
I chose option 1, as it was was 160 bucks on newegg. Totally worth more than it would be to dig and fix. (it also requires a download of the install file, as there is no media)
As to option 2, rolling back the update can be difficult, because I couldn’t find the update. I didn’t dig, but it may be included in a service pack or corrected by another update.
As to option 3, I don’t recommend it because dll’s frequently have to be registered on the system. A find and replace could have very bad effects on your office – even breaking it.
MS replaced mso.dll in the update. However, as far as I can tell, permissions in Vista are messed up. The program does not have the ability to fix bad registry settings and so ends up in a bad state. The workarounds that I’ve been reading about sound arduous and annoying, if they work. As Office XP is 8 years old, I’m guessing good old M$ doesn’t care if the old version is broken.
Hope that Helps.
