Visual Prifiler (64bit) 4.1 rc "unable to collect events and metrics" null

Just tried visual profiler and it does not want to work, after running program it just posts message

“unable to collect events and metrics” and print “null” under the message.

timeline was created, but multiprocessor, kernellmemory, kernell instructions do not work. First they print something about different kernell order, but I resolved this issue. Cound it be because of I use 64 bit profiler for 32 program? But I use win7 64 bit, so I installed 64 bit SDK.
