Thanks for the answer. I just had the same idea actualy. Right after I tried to reinstall SVP... xD
New install fixed the problem but I guess that open svp4-maintenance.exe directly would have worked too.

Thank you !

Hi.

I just purchased SVP Pro.
I want to try SVP on VLC but I can't install the fonctionality cause "Additional programs and features" won't open. Nothing happens.

Thank you.
