I have a Compaq Presario computer with Windows XP pro 32 bit.  I installed a legal COPY of Office 2010 office plus. When I create a new ACCESS database the titlebar on the top has Access 2007. I don't have Office 2007 on the computer. The problem I have is that I can't save a mail merge document in Word using my database. The error message tells me to go to the trust center but with no further instructions. I googled my problem. The solution told me to uncheck all of the boxes and I could save the document. That worked but it only prints the first line in the database. If I don't save the document I can print the whole database.Was Office 2007 installed on that computer prior to installing Office 2010?  If you open Programs and Features, do you see Access 2007 or any Office 2007 components listed there? Office 2007 was on the computer before. When you go to programs it is not there anymore. I removed it when I installed 2010.I think I would uninstall Access and then reinstall it.  See Install or remove individual Office programs and components for guidance on the procedure. 

Edit: My reasoning is that you MIGHT have inadvertently not selected, or unselected Access 2010 when you installed Office 2010 and, therefore, Access 2007 was retained from your previous installation of Office 2007.  And, in the same vein, you might not have fully removed all Office 2007 components when you installed it. Just wanted to mention that I have seen similar issue with an HP Pavilion computer a while BACK with a different piece of software which was Roxio Easy CD Creator 4.0, in which I had an orphan registry entry cause havoc when trying to install version 5.0. The problem was that the HP image that came with that system and restore discs had orphan registry keys for Roxio version 4.0 when version 4.0 never came with that low end Celeron when bought new. ( I guess HP decided to improperly remove Roxio 4.0 from a different build and make that the system image for this lower end model to have this happen. There is no other likely cause for this orphan key issue. ) I had to fix the flawed registry which was part of the HP system image into order to get my CD-Burner to work with Roxio 5 that came bundled with it.

If you find that Access 2007 is not installed and it still thinks that it is... you can try Karenware Registry Pruner http://www.karenware.com/powertools/ptpruner.asp  She created a bunch of neat programs before she passed away and her brother is keeping her site online. This one saved me from hours of headache. I was able to find the problem and remove it, then install newer Roxio 5 to my system and be able to burn CD's
