Hello There, My previous version was expired. I chose the 3 version, as this is cheaper than 3x a single. In XP and Win7 installation went smoothly, with my Vista_PC mucked the routine suddenly with incompatible operating system. A chat with the hotline was very quick gg 18 h and there was one on which any SP 1 was missing. This I then anchinstalliert and lo and behold - Perfect. However, I have the update installed a few days later than in the other two PC's and the day you told me then deducted the same. I have not been with all versions had major difficulties and the hotline has been very nice and fast. The only drawback: the installer could dezedierter respond to the error, whether a SP 1 is missing or the whole BS is broken, you should query at the present time already can.
