as per: https://bugzilla.mozilla.org/show_bug.cgi?id=786037 talos-r3-w7-080 -> 099, were imaged in August, these are the exact slaves which report failure for our xperf runs in: https://bugzilla.mozilla.org/show_bug.cgi?id=803413 Please ensure these machines have the latest mozprofilerprobe.mof: https://bugzilla.mozilla.org/show_bug.cgi?id=778856

How can I check this?

I don't know of anyway to check this other than if the xperf stuff runs. Otherwise we could manually install the .mof files and cross our fingers.

This is what I'm getting: C:\Users\cltbld>mofcomp c:\Users\cltbld\mozprofilerprobe.mof Microsoft (R) MOF Compiler Version 6.1.7600.16385 Copyright (c) Microsoft Corp. 1997-2006. All rights reserved. Parsing MOF file: c:\Users\cltbld\mozprofilerprobe.mof MOF file has been successfully parsed Storing data in the repository...

I believe you need to run this in an administrator command prompt (this resolves any UAC or related permissions).

Armen, I don't suppose you've had a chance to try with an elevated command prompt? :-)

If I run it with admin privileges (no UAC is involved) it actually succeeds: http://cl.ly/L69Z In fact, the instructions on the ref page mentions it [1]. From looking at slaves 100 and forward I can see that the win7 snapshot has the file plus rail filed a snapshot bug (bug 784304 - completed on 2012-09-10). The actions to take are: * releng to deploy through RDP or VNC the file to slave talos-r3-w7-0[80-99] (verified that they don't have that file) (oh pain) Let's try to do this tomorrow.

I fixed this today. Please let me know if this re-occurs.
