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

Good morning.

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.

Re: Can't install McAfee agent | Error 1904 ..\ma_compat_agent.dll failed to register

Hi, even on Mcafee Agent 5.6.1?

Yes. I tested the various 5.6.0 up to 5.6.0.940 and 5.6.1.157.

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.

 

Re: Can't install McAfee agent | Error 1904 ..\ma_compat_agent.dll failed to register

We just ran into this issue on a machine (Windows 10 and still 1809.

We are trying to install 5.6.1 and it came back with this:

"C:\Program Files\McAfee\Agent\x86\ma_compat_agent.dll failed to register.  HRESULT -2147024409.  "

A service request has been issued.

 

*note- we ran the uninstalled twice and still received this error.

I have been testing with agent version 5.6.1.308 and it has gone well so far.
