M520 has no os driver pack and installing os driver pack is not possible

Hi,

I have a M520 with Windows Server 2012 R2 where OME says the os driver pack version is 0. It's not possible to install the current version of os driver pack (15.07.07). I tried several ways:

- via OME

- starting the .exe in the OS

-via Enclosure

The server is the OME-Server itself.

This is not a heavy issue, but it's strange. There was originally a version of the os driver pack when the server was delivered by Dell. I installed the server with this. There are 15 other servers in the enclosure, M520 and M620. No other machine has this problem.

Any idea?

Greetings Barbara
