Multiple EA versions on the same machine?

[GClaes]

I did a search and could not really find anything other than that a beta version can run alongside a previous version of EA.  Can EA 10 be installed on the same machine with an older version like 7.5, 8 or 9?

Yes. Zip the old EA program folder. Install the new one. Unzip the old under a dedicated name (e.g. EA7, EA9.3). You can then start EA.exe from out of these folders. There are almost no compatibility problems. The worst would be that you get strange results accessing a new EA repository from an older version. And that only in a very small area (AFAIR enumerations have changed).

Hmm, that is not acceptable as the installation is done in bulk via an installation package and I doubt a workaround like that will be accepted.

When installing EA10 and a previous version is detected the installation process displays an upgrade warning which allows an automatic uninstall of EA8.  Does this also work smoothly for EA7.5?  Are there any known problems doing this?  Can EA10 open EAP files created by 7.5 and 8?

Yes, no (except see above post) and yes.
