Patch content

Compressed VBS script for WMI queries

Should you install this patch?

Apply this patch if you need to query a WMI class whose provider is only available in 64 bits. You can query the 64 bit class through other interfaces, like WBEMTEST.EXE but you get an "INVALID_QUERY" error message in Monitoring Studio.

What does it fix?

Some WMI providers are available in 64 bits only. As the PATROL Agent version 3.x is only 32 bits, it cannot access the pure 64 bit WMI classes (the problem is the same for any child process of the PATROL Agent). The new VBS script forces the WMI client component to address the 64 bit version of the WMI provider, even if originating from a 32 bit process.

How to install the patch?

  1. Uncompress the content of the following file to the %PATROL_HOME%\bin directory on the managed server:
    • SW_WMIlib_query.zip
  2. The patch takes effect immediately. Nothing needs to be installed on Console systems.
