Hello,
We're using the 14.3 RU8 version of SEPM, we recently discovered that the SEP version running on one of our servers is corrupted, this version was 14.3.10148.8000, so as the basic steps we used the cleanup tool to delete it.
We send a remote installation command through the SEPM server including the cleanup tool as an option.
Unfortunately, we're running a GPO that deploys the SEP client on all our devices after rebooting.
After viewing that the remote installation didn't work, we manually launched the cleanup tool and tried to install the SEP client without success.
As attached you find the error returning by the windows server and the logs of the the remote deploy.
