Unable to remove broken Eset 4 installation

Recommended Posts


recently we got a new customer and and I wanted to install and update all eset installations on the customers clients and servers. 

I have problems to do so with one Windows Server 2008R2 virtual machine. There is/was Eset 4.x installed but it does not work properly. 

When I try to start its UI I get 


The Eset 4.x installation is not listed in "programs and features" but there are files and directoires under "C:\Program Files\ESET\ESET NOD32 Antivirus" and "C:\ProgramData\ESET\ESET NOD32 Antivirus".

Nonetheless I was able to install our "Eset Remote Administrator Agent". Installing a Eset FileSecurity via Remote Administrator windows error log says 


When I try to install FileSecurity manually I get



EsetUninstaller finds one AV product


But I think that is the Eset Remote Administrator Agent and won t work.


Does anyone have any idea how to solve this problem?

Uninstaller shown to you, that there is ESS / EAV / EMSX. That was also EFSW 4.5 identified. You should use the newest uninstaller, and be sure, to run it in the safe mode. That should be the safest way, how to remove EFSW 4.5.

The version that you are using is obviously older, as the new one also detects the ERA Agent (the old was not able to).
