I had to change my HDD.
Reinstalled Windows7 and I can't install Corel Motion Studio.
I have tried many things.
I read in Internet that perhaps my Windows needed Microsoft Framework 4.0.
I downloaded it from Microsft and when I was installing it told me that there already was installed a newer version of Framework.
Motions Studio iniciates the instalation but suddently stops showing a very quick message ( impossible to read ) and stops.
I have downloaded a trial version of Motion Stduio and the same happpens.
