Hi there,
I've got a trouble with AVG Free and Tuneup and the code error is 0xC000012f [ C:Program Files (x86)\AVG\Framework\1\avgcmlx.dll ]. I've read in the forum support that is an inconvenient for other people and I've tried to use AVGRemove without any success.

How can I do to fix this matter? I like Avg pretty much and it's the first time I can't do nothing without help!
Thank you and best regards

Camilla
