Can't read performance counters for an OPCInt instance

Hi all!

In an interface node, I have three OPCInt instances.

I can read performance counter for just one of them.

I have tried rebuilding Widows performance counters and fixing specific PI counters via pidiag, but it didn't work.

1. Open Cmd Prompt as an Administrator
2. Navigate to C:\Windows\System32.
3. Run Iodctr /r.
4. Now navigate to C:\Windows\SysWOW64.
5. Run Iodctr /r.
6. Now Navigate to %piserver%\PIPC\adm.
7. Run the pidiag.exe –cpc –fix.

I see in the registry that the services I can't read do not have a "Performance" subfolder like the other that I can does.

I have tried uninstalling and reinstalling the services to see if something would chance in the registry, but it didn't.

Any ideas?

Regards
