Uninstalling DLP Agent (12.5)

Hello there, 

I have some trouble uninstalling a DLP 12.5 agent. I have tried the following ways:

1. msiexec /uninstall {product code} /q UNINSTALLPASSWORD=""
2. Manually uninstalling from Add/Remove Programs (we did not use the optional ARP switch when installing)
3. Uninstalling by using wmic switches. 

I have installed 12.5 agent without the UNINSTALLPASSWORDKEY defined. When checking the logs, I see an error failing to read UninstallPassword, check if Keystore database is in correct state. 

I have attached a copy of the uninstall logs here. Also, is there a clean tool that I can use to deploy remotely?

Thanks.
