Uninstall DLO agent without *.msi

Hi,

we need to install dlo agent 7.5 on pc that have installed a previous version of DLO.

I tried to unistall the previous version and then i tried to upgrade from server share "DLOAgent", but the advice is the same....it cannot find the path of  *.msi to unistall the previous version. But we have formatted some month ago the older server and install BE2012 and DLO 7.5 on a new server.

How can i solve this issue?

Thank you
