dam, i fixed it myself lol.
after 2 days searching all over the net! noone seems to fix this .. I MADE IT ALONE! lol
ok i explain what i did:
i found another installation problem in java.
i uninstalled it with revo uninstaller. deleting all the things.
reinstalled it but i dont think it was the problem because same probleme was there with corel videostudio.
after that i verified once again in "windows install clean up" software. and i realized "common 14.0.0.342"
i noticed "14.0.0.342" was the same version as my Corel VideoStudio.
so i uninstalled allllllllll others softwares with the (14.0.0.342) from "windows install clean up".
i rebooted "common" problem was gone finally.
and i could finallllly re-install Corel VideoStudio.
Rebooted but still .. When i clicked on my desktop icon "Corel VideoStudio", it won't open.
So i uninstalled it once again but from "revo uninstaller" deleting all things.
Rebooted.
Reinstalled once again Corel VideoStudio.
Rebooted.
WORKED!
It was just REALLY bad uninstalled.
Had to reinstall it to well uninsall it

.
and reinstall it lol.
hope it fix your problem too.
