Office 2010 is not default for xlsx, .pptx, etc

Hey Folks! I installed Office 2010 alongside Office 2007 on an XP Pro machine. The 2007 file extensions are defaulting to 2007 when I open those files. I want them to default to the 2010 version. I have tried using Open With... and browsed to the 2010 executable file and setting it default that way, but 2007 still is default when opening the file. How can I make 2010 the default version short of removing 2007 if possible?

Well I am on XP Pro and I don't see any options for Office in the default programs. Also, having them installed on the same machine is not creating crashes or anything, just things are opening in the former version. If there is no setting I can configure, honestly, I will just uninstall 2007 and move on. Is there no place to set this default?

Yeh it's in explorer settings (Not Internet explorer)

might help...


I already tried that myhc, it just continues using 2007 even though I manually go to the 2010 executable using Open With and Browse. But thanks for trying!

i would have one in a free Virtual PC . lol


Yeah that is what I have read a lot, I just thought there had to be a setting somewhere that would allow me which version would open as default since the cutom install of 2010 allows you to keep previous versions of the software. I think in the end though I will be uninstalling 2007 since that is just going to be the simplest solution for the user. I will hang out on this question til tomorrow just in case anyone has an idea. Thanks!

yeh, the actions taken should complete the task.


I have decided to just go with uninstallation of 2007. It is the simplest and "cleanest" way of dealing with it. Thanks folks!


There were many points of advice in the solution, but I am going with uninstall one of the versions
