Windows 7 - Can't open Office 2007 files with Office 2010!

I now have a new problem, before I managed to open 2007 files by opening Office 2010 and then from inside the application choosing to open a file. The problem I have though is if I just try to open an Office 2007 file then I can't open it, and I can't change the default program to open it.

How do you get Office 2010 to open all the Office 2007 files such as word, excel etc?

please don't cross post

This is not a cross post it is about something different, which required a new thread, so please get your facts right!

LOL. Okay, lemme see if I can get my facts straight.

Find the file type you would like to associate with Office 2010. Right click file, OPEN WITH->CHOOSE DEFAULT PROGRAM->BROWSE (if necessary to find Office 2010 executable), and make sure the checkbox is selected to "Always use the selected program to open this kind of file."

I have already tried to select Office 2010 but it wont let you do it for some strange reason.

Try this.

Close all Microsoft Office Product (including Outlook).

Go to CONTROL PANEL, UNINSTALL, find MS Office 2010. RIGHT click on it and select CHANGE. Select REPAIR and let it run.

My documents were made thru word '07. When I tried to open my documents with word '10, it says ".doc is not a valid win32 application" while in fact it was done from 32bit. I tried opening it on a PC (OS Vista) with word '07 and it was a success. Is there a program or a patch needed for word '10 to open those documents? Looking forward for a solution of this concern. Thanks..!

Check the File Block Settings in Trust Center for Word. File versions that are checked are blocked.

Open Word, click File, click Options, click Trust Center in the left column, then click Trust Center Settings in the right pane. Click File Block Settings in the left column. Here you will find all the file versions that Word can open and/or save. If the box is checked, that version is blocked. Check or un-check the files you use.

Take a look at this article on converting older versions to 2010.

Convert Older Office Documents to Office 2007 or 2010 Format

It is really directed at 2003 files, but the process may be the same (or similar) to converting 2007 files to 2010.
