I installed latest MYSQL additonally now, instaled owncloud then which worked now.
But to have it working right away withing your great ampps installer, would be even better ! didn´t have these problems with 2.1 before.. the upgrade from 21. to 2.2. also didn´twork for me.. apache and mysql not starting anymore.. so I had to go with a clean install of ampss 2.2..
Tried this on 2x windows 7 machines and finally a windows 8 machine, always ending up in the same bad result.
