The installation of CrowdStrike on a machine with Apex One Agent installed on it can lead to errors when the CrowdStrike installer tries to uninstall Apex One Agent driver. This is due to incompatibilities between Apex One and CrowdStrike, as they both are Endpoint Security Solutions.

When CrowdStrike Sensor Agent installation is run, it will execute its uninstaller tool (CSFalconServiceUninstallTool_x64.exe) to try and uninstall the UMH Driver (TmUmEvt64x.dll) of the Apex One Agent and show the error message below:

Since the issue is caused by CrowdStrike Sensor Agent's installation process, we recommend seeking assistance from the Vendor's Support.
