I don't know why i can't install McAfee agent.The error massage is Error 1904 Module C:\Program Files\McAfee\Agent\ma_compat_agent.dll failed to register. HRESULT -2147024769. Contact your support personnel. Please reply me if you know how to solve this issue.
Possibly associated software packages are mismatch,
you can try ignoring the alert and try manually register the specific dll by using the below command
regsvr32 C:\Program Files\McAfee\Agent\ma_compat_agent.dll
I have a case open with McAfee support for this issue. What I am told is that there is a bug (or two) and that there will be a new McAfee agent release in the future.
Yes. I tested the various 5.6.0 up to 22.214.171.1240 and 126.96.36.199.
One work around that improved the chances of success was to run the McAfee Endpoint Product Removal tool and remove ALL products (even if there were none ever installed). Then reboot and the agent install *may* work. This workaround was not always successful.
I believe agent 5.5.1 does not have this bug, so if you can use that it may also be a work-around.
