Installation package size exceeds the maximum size limit in McAfee ePO. Choose one of the following:
Software Catalog (Software Manager on McAfee ePO 5.9.x) is busy checking in required software packages. Wait until the packages are checked in, then begin installation again.

Or, if another task is updating the Software Catalog (Software Manager on McAfee ePO 5.9.x) , you can stop the task.

Root certificates are missing. Install the latest root certificates, which are required to validate the digital signatures of product files. Missing root certificates can also cause fields not to populate (KB87096).
Files were left behind by a previous installation of Endpoint Upgrade Assistant. Remove these files before attempting to install Endpoint Upgrade Assistant again.
The products you removed were reinstalled before Endpoint Upgrade Assistant could install the new versions. Disable features that detect uninstalled products and reinstall them automatically.

Products don't work as expected

Best practice: For optimal performance and protection, install the same version of the Endpoint Security modules or upgrade all modules to the latest version.

Use these recommendations to resolve unexpected behavior in other products after installing Endpoint Security.

If... Then...
Third-party applications aren't working correctly after installing McAfee Host Intrusion Prevention, and you didn't preconfigure custom Firewall rules. Enable Adaptive mode to determine whether Host Intrusion Prevention is blocking those applications.
Common Event Enabler (CEE)/Common AntiVirus Agent (CAVA) was running with Endpoint Security before the upgrade, and the upgrade occurred without CAVA.

Reinstall Endpoint Security, using the /CAVA command-line option (KB88973).

If you don't use the command-line option when upgrading from a previous version of Endpoint Security with CAVA, the upgrade occurs without CAVA.

The endpoint stops responding (hangs) when memory protection features in McAfee Application Control, McAfee Change Control 8.x or 7.x, and Endpoint Security or Host Intrusion Prevention are running at the same time. Disable Application Control and Change Control memory protection features, then use the Endpoint Security or Host Intrusion Prevention memory protection features (KB81465).
You want to check that Real Protect is installed correctly and that endpoints can communicate with the McAfee cloud for detections. To test Real Protect detection functionality, you can download and run password-protected test files (KB88828).
