Commented Unassigned: Unable to generate Report [24855]

I run the PAL utility thru all the tabs. it chugs along on the perfmon file i have. The message appears ' generating the html report...done' appears. this is followed by the the path and filename ending in htm. The the warning message and this:
Invoke-Expression : Program 'Performance_Counter2013340610_PAL_ANALYSIS_2013-11
-06_15-54-11.htm' failed to execute: Application not found

i have installed mschart. my machine is running powershell 2.0. i do have .net 4.0 framework install. have not been able to upgrade to 4.0 powershell, even after running the dotNetFx40_Full_x86_x64 executable. thought the website says to use 2.0 anyway. Any insight would be appreciated. thanks.

This looks like you don't have a browser associated with *.htm files. That command is trying to open the resulting HTM file. Can you confirm if the HTM file actually gets created?
