Can I install MS Office 2013 64 bit on the same pc that has MS Office 2007 Pro?

I have just purchased MS Office 2013 Pro and tried to install it on my PC which already has MS Office 2007 Pro installed. I want to keep 2007 because I have numerous 2007 MS Access programs that I maintain. When I tried to install 2013 it tells me I can't load the 64 bit version because of the 2007 32 bit version. Is there a way around this or do I need to install the 32 bit version of Office 2013? What are the drawbacks of using the 32 bit version of Office 2013?

Yes. But you can have only one Outlook (either Outlook 2007 or Outlook 2013). There is no drawback in installing 32 bit of Office. In fact it's better and Microsoft indeed recommends it.

Just to add a bit; there are far less drawbacks than pluses.

 The only thing the 64 bit version allows you do to is have spreadsheets in Excel >2GB in size and large projects in project.   Outside of that, there is nothing else it offers.

 On the other hand, there are many drivers and add-ins that only come in 32 bit versions.

  So your far better off with the 32 bit edition and as has been said, even Microsoft itself recommends that most users should install the 32 bit edition.

As far as having two Office versions on the same computer is concerned (even one app from one Office version and everything from another), this can cause problems regardless of the 32-bit/64-bit issue, especially if you transfer data between Office apps.  It is best to install the other Office version in a VM.  I have Office 2010 installed on this computer, with VMware supporting VMs for Office 2003, 2007 and 2013, for when I need to work in those Office environments.

Thanks Helen. Good idea!

If you don't want to run with VM's for some reason, you can get away with multiple versions in general if:

a. You install oldest to latest
b. You always install each to a separate directory.

  Right now the station I'm on has A97, A2000, A2002, A2003, A2007, and A2010 all loaded on it and no real problems with any other than from A2003 and up it needs to re-configure when Access starts.

 VM's are the way to go though if you can do that.

Thanks Jim. I ended up installing my 2013 on the same machine as my 2007 without any further problems. The only issue I faced was the 64 bit issue but now that I know that I don't need the 64 bit version all is well so I decided not to run virtual machines.
