Error 0xe0000247 installing OES client IR12 on W2k12


I get this error "unknown installation error occured: 0xe0000247" during install of oes client.

All modules are successfully installed (nici, nmas and so on), but the install of the client itself failed.

Same error with the IR8 version of the client, so I have to assume, it´s a problem with the system.

W2K12, not activated yet, installed in german, 2xX5650, 120 GB memory (recycled vmware host) on HP DL360

Any hints?

Thx in advance
