Quartus 11 crashes, WIN7 Pro 64 bit

Hi all.

I have a problem with my new Dell R5500, WIN7 Pro 64 bit.

After installing Quartus 11, program crashes immediatly after I start it.

Nother installing SP1, nor downgrade to Quartus 10 didn't help.

Log file of the error I get, attached here.

I''l be glad for any help.

Thanks.
