After a server crash Kesc was corrupted and I had to remove it to reinstall. That's the problem, since that date I can't reinstall KES on this server, the process hangs for hours and is not completed. Does anyone know if there is incompatibility between KESC and server 2008 R2? After uninstalling KESC I used the KavRemover tool to remove traces of the previous installation but I still can't reinstall KESC 11.5 Help needed
