Microsoft Excel Office 2007 converter problems

I loaded Office 2007 and then had to uninstall it and I just loaded Office 2003.  I had some problems where I had to eliminate everything out of the Registry for Office 12 and then I also had to rebuild the MAPI files in order to get it working.  I seem to have resolved those issues, but the issue I have now is that when I load the Office Converter 2007 enabling me to view and work with files created in the 2007 version from the 2003 program upon converting I get the following message from Excel:

"Microsoft Office Excel is waiting for another application to complete an OLE action."
Then after I click OK I get: "The converter failed to open the file"

In Word I get:

"There was an error opening the file"
and on the bottom I get a message that states, "Wordconv.exe was closed.  To help protect your computer Data Execution Prevention has closed wordconv.exe."

I disabled the Data Execution Prevention and the Word and Excel files would not open still.  Please advise.  Thanks.

I reloaded the OS and after loading Office 2003 it works fine as the conflicts seemed to be resolved.

You have some serious issues with missing registry. Since we don't want to do a complete rebuild I would go back to square one. Uninstall office 2003. Then do a full install of office 2007, reboot.  Then uninstall office 2007 and do a complete install of 2003, reboot. This way you should get your missing keys restored.

I backed up the Registry prior to deleting all of office 2007 registry entries.  I have imported that registry back and it still did not work.  I am now uninstalling Office 2003 and will reboot and then try to re-install.  Any thoughts?

I reloaded the program and it is exactly the same.  I do not believe it to be a registry problem since I imported the registry just as it was before I deleted anything.  Please advise on if you have any other suggestions.  Thanks.
