MS Project 2010 and 2007

[RobertClancy]

When I try to open my .mpp files that I created with Project 2010, I get an error message indicating that the 2007 version (I doesn’t have Office 2007 on my PC) is trying to open them and that I need to install a converter. Any suggestions on how I can make 2010 to open my Project files? (I'm running Windows 7, if that matters.)

You will need to follow these steps exactly to make the 2010 version default.
Right-click on your .mpp file and select Open With.
Then select "Choose default program"
Then select 2010 version from list, if it's not there use Browse button to point to 2010 version
then place a chekmark on "Always use this program to open this kind of file"
then click OK.
