I installed Lion. It took several hours!
I found out after, that several softwares I was currently using do not work any longer (FileMaker, Excel, Word).
Can I downgrade now? Or would it be possible to run both systems on the same machine?
I have previouly saved my disk with Time machine.
MacBook Pro, Mac OS X (10.7), Any answer in French is welcome
You can downgrade, but it's not easy. Search these forums for "revert to snow leopard" for numerous answers.
However, MS Office can be made functional by simply upgrading to Office 2011. Also, my ancient copy of FileMaker Pro 8.5 seems to be working fine in Lion. What version are you using? Of course, the ultimate solution would be to simply upgrade FMP as well. If you're going to upgrade your system, you're going to also have to upgrade your other software from time to time.
To run both systems, you could create another partition on your hard drive with Snow Leopard, and then choose which system to boot into. That would be inconvenient, though. You'd be better off to simply commit to Lion and upgrade your other software or bite the bullet and revert to SL. Of course, if you do the latter, you're stuck with that machine and that system until you ultimately are forced to do the former by hardware failures or whatnot.

next time look at system and softwear requirments. Apple said that Office 2004 would not work. Upgrade 2004 *****.
I will check if all data are working fine with IWork
Do you really think that your answer is useful?
Just want to point out that Apple insists much more on what will be working and not the reverse…
Thank you for your clear and useful answer
