I had FM11 pro adv. on my pc. I bought an upgrade to FM13 pro adv and installed it.
Can I remove FM11 now? Or do I always need it to be present on my pc in case of reinstalling FM13?
You can remove it. Keep the registration number.
And keep your installer files for both versions. That way you can reinstall FMP 11 if the need arises (Say to examine an old back up file or to help someone else out that still uses the older version...)
So that means that when I have to reinstall FM13 I have to reinstall FM11 first and upgrade FM11 to FM13.
There is no way to reinstall FM13 from the upgrade .exe file without having FM11 installed on the same pc?
You can install FMP 13 upgrade without FMP 11 on your computer. When upgrading to FMP 13, it will look for a prior version and when one is not found, it will ask for a registration number from an earlier version.
