I am getting the following error and unable to get past this. Is there anything I am missing?

MergeConvertFilterPerfmonLogs : Relog.exe failed to process the log. Review the
 results above this line. If relog.exe continues to fail, then try running Relo
g.exe manually and/or contact Microsoft Customer Support Servers for support on
 Relog.exe only. PAL is not supported by Microsoft.

PAL uses Relog.exe (part of the operating system) to help with parsing of the counter log.

Most of the time this fails when you are trying to analyze a counter log captured on Windows Vista/2008 Server or newer on a Windows XP or 2003 Server. The log file format changed and XP/2003 computers cannot open the BLG file. If this is the case, then install PAL on a Windows Vista or newer operating system and analyze it there.

I updated the error message in PAL v2.0.8 to include more information about running on Windows Vista or higher and about possible log corruption.

Thanks Clint.... Finally i was able to resolve this by correcting the "Threshold File Title" to use .NET Framework it worked well.

I don't see how that would have fixed it, but okay. Please elaborate more if you are willing.
