The Monitor Solution Plug-in fails to install on a client machine. The agent shows that the install task failed with exit code 0, however the agent logs show that the install task failed with exit code 1603. The Plug-in fails to install when run manually as well.
Most likely there are left over files or registry keys from a previous Monitor Plug-in installation preventing the install.
Download and run the Microsoft Fixit tool:
https://support.microsoft.com/en-us/mats/program_install_and_uninstall?wa=wsignin1.0.
When prompted by the wizard specify that there is an installation problem and select the Monitor Plug-in as the software with the installation problem and then the Fixit tool will cleanly uninstall the Monitor Plug-in. After that the Monitor plug-in should install successfully.
It may be necessary to run Fixit tool to fix Pluggable Protocols Agent as well.
