Scenario: While trying to install the Client Automation Agent the installation fails with the error: CA DSM DMprimer: The current PATH environment variable is too long.
Resolution: This error occurs when the PATH environment variable length/resultant length is more than 2048 characters. This is a Microsoft Windows OS limitation. Try reducing the path length or changing the installation path of the Agent to a shorter path.
Please refer techdoc TEC471128 for instruction on changing the Client Automation default installation path.
Disclaimer: If the path length cannot be shortened using the approach outlined above, please contact Microsoft for assistance.
