Can't see the Asp .Net V1.1.4322 Performance counters

Hi:

I'm a software Enginering of QA for application in .Net I use a lot the performance monitor included in the windows OS, normaly I can see the application runing in the ASP .Net, I just need open the monitor and choose the ASP .Net Apps V(Number of version), recently we migrate some applications to a 64 bits server and actually is not possible see the applications runing in the Version 1.1.4322 In a 32 bits server I can see a counter for all version of ASP .Net Apps.

some idea about this issue? I need run some update? or witha 64 bits server I will don't allowed to see the counters?

Thanks a lot.
