Unable to locate component DPSUI.dll when launching Performance Analysis



'dll not found' error for DPSUI.dll when attepting to launch 'Performance Analysis'


This article applies to DevPartner Studio Performance Analysis 7.x version.

Problem: Error: nmstart.exe - Unable To Locate Component.

CONTENT: This application has failed to start because DPSUI.dll was not found. Re-installing the application may fix this problem. Or unable to find DPSUI.DLL in the path:...

Cause: This is because that the install path for this DPSUI.DLL is not in the system path. During the install, DPS tries to add the following path:

[ROOT]:\Program Files\Common Files\Compuware\ MShared;

[ROOT]:\Program Files\Common Files\Compuware\DevPartner Studio\Analysis;

[ROOT]:\Program Files\Common Files\Compuware\DevPartner Studio\Distributed Analyzer;

into system path. If the system path is too long (over Microsoft limitation 1024 characters) or the previous version was not completly uninstalled (using Add/Remove Programs), the next installation may fail to add the above path into system path.


Make sure that this DPSUI.dll is registered. Otherwise, register it using regsvr32;

Manually add the above path for NMShared into your system path. Please check other two as well to prevent other potential problems.
