Kes 11.5 Wont install on server 2008 R2 [MOVED]

[´Johnkeeper]

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
