This post describes how to manually remove the VMM Agent (2008R2) from an Hyper V Server 2008 R2.
This procedure help me when I find some remaining rest of an old installation of a virtual machine manager Agent.
First we will need to open the regedit and perform a full backup. Then we follow the steps below.
1- Navigate to:
HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Installer\Products
2- Fin de Key for Microsoft System Center Virtual Machine Manager Agent
3- Copy the Code from ProdutIcon string "{A371D6FD-4635-4B65-84AE-D83FD91DF905}"
4- Open an elevated command Prompt and type the following
msiexec /X "{A371D6FD-4635-4B65-84AE-D83FD91DF905}"
5- Confirm the uninstall
