SIM, Windows Server 2008 64-bit and search path

[Ulf Zimmermann]

I have SIM 5.3 SP1 installed on Windows Server 2008 64-bit. As SIM is a 32-bit application it got installed into C:\Program Files (x86). The PATH variable is set to several directories below, like to C:\Program Files (x86)\HP\Systems Insight Manager\bin

One of the additional plugs I am trying to install expect mxcollections in the path. It is at the above path. Based on PATH I should be able to execute mxcollections from anywhere in a cmd shell but it just says it doesn't find it.

Any idea what is wrong? The whole %PATH% is:

C:\Program Files (x86)\HP\Systems Insight Manager\bin;C:\Program Files (x86)\HP\
