Yes, they can be run on the same machine. Have been doing this with 10-12 during upgrade periods.
Thanks for the quick reply, starting on the installation of FMP12 now.
Have you been running them at the same time, on the same machine, accessing the same data files?
i have had runnign at same time. However with v11 and v12, you cannot access the same data files as they are 2 different formats.
Understood about 11/12 file type difference... but you had mentioned 10-12 so my question was related to running 10 and 11 at the same time
I have had issues doing this on occasion, especially on Macs so I stopped running two instances of Filemaker at the same time on both platforms.
Was just currious what others had found when running 2 different versions at the same time whether on the same set of data files or not
Not accessing the same files while running 11 and 12. My files running in FMP11 are .fp7, I only wanted to run FMP12 on the same machine so I could get familiar with it and do a test on the file conversion in advance of the office-wide upgrade to see if there were going to be any issues.
You can certainly have multiple versions of FileMaker Pro installed on a single machine at one time. You can also typically run multiple versions of FileMaker Pro at the same time on Windows as long as they deal with different file formats. So, you could have FileMaker Pro 11 and FileMaker Pro 12 running at the same time if you'd like. Where you will run into problems on the Windows platform (the Mac OS platform is much more forgiving) is trying to run two versions of FileMaker Pro at the same time that deal with the same file format. For example, you could not run FileMaker Pro 10 and FileMaker Pro 11 at the same time.
And, as alluded to, you should NEVER try and have two versions of FileMaker Pro access the same file at the same time without hosting the file. FileMaker Pro will likely throw up a "file in use" error if you try but if you somehow are able to circumvent that message you are just asking for trouble in a single user file. Just say no!
But the original question deals with installing on Windows 7 and in that case you can absolutely have multiple versions installed.
If you have both versions opened at the same time, only one version will be able to share files at the same time.
