General question.................I'm running Office 2010 32bit version on a 64bit machine. Can I install, without removing office 2010, Office 2013 64 bit edition and run as well. ????
I've assumed yes as files would be in installed in the 'Program Files' folder whilst Office 2010 files are in 'Program Files (x86)' folder.
According to Microsoft this will not work, they state that all 32bit versions must be removed when installing a 64 bit version. it is possible to run the 32 bit versions of 2010 and 3013, but it's not recommended and may cause serious issues
Information about how to use Office 2013 suites and programs (MSI deployment) on a computer that is running another version of Office
Many thanks for he quick response. I tried to install but got an error message that stated 'Setup cannot find or validate an installation file......." I trust this would be as a result of attempting the install ???
Reading the knowledge base article it should present a specific error about the presence of the 32 bit files but the general error could be related.
The major issue if you choose to run the 32 bit version of 2103 and 2010 together is that there will be a delay every time you start the application whilst windows resets all the associations, this can often add a delay of several minutes to the start up of word and such. there is a way of adding a registry key to prevent this but can still be problematic - The KB article I linked to should give all the step by step instructions plus the background
