32bit & 64 bit on same computer ??

[DocBrown]

If you have Office 2010 Prof Plus x64 installed, can you install Office Standard 2010 (32 bit) on the same computer to run a certain MS Access (32 bit) program database that will not work with 32 bit?

DocBrown, it seems that you can't have both versions on the same computer. Below is a copy from my Office Pro 2013 Help files explaining it. Also you can't even run say Office 2010 in 32 bit & Office 2013 in 64 bit. It a case of either or, but not both.



Why can’t I install both the 32-bit and 64-bit versions of Office 2013?

The 32-bit and 64-bit versions of Microsoft Office programs don’t get along, so you can only have one type installed at a time. If you want to install a mix of 2010 and 2013 programs, the type still needs to be the same. Either install the 32-bit or 64-bit of both versions—don’t mix the types.

To help you decide which version to install, please see Choose the 32-bit or 64-bit version of Office 2013.

Install the 32-bit version of Office

After you have uninstalled any 64-bit versions of Office, when you run Setup, it defaults to installing the 32-bit version.

Install the 64-bit version of Office

Important If you already have a 64-bit version of Office installed on your computer running a 64-bit operating system, running Setup from the root folder installs the 64-bit version of Office.

2.Click Yes to cancel Setup, and then click Close Button image.
3.Go to the x64 folder on the Office disc, and double-click Setup.exe to run the 64-bit version of Setup.

From My Account
1.Go to My Account on Office.com.
2.Click Language and Install Options > Additional Install Options > Office 64-bit > Install.
