HP Windows 2012 Foundation ROK - cannot install DotNET 3.5

Hello!

Have recently purchaded an HP Proliant ML310e Gen8 + HP Windows 2012 foundation ROK

( system info says build is 6.2.9200.16442 )

The purpose for the server is to run Autodesk vault 2012. This has some prerquisites: ISS and DotNET 3.5.

In the server manager there is the option to add support for DotNET 3.5, however it fails:

Add roles and functions faiils with: could not find source files.

I have tried some suggested solutions, like copying the source directory on the dvd to a folder on the server and using

dism:

xcopy d:\sources\sxs\*.* c:\net35 /s

Dism.exe /online /enable-feature /featurename:NetFX3 /All /Source:c:\net35 /LimitAccess

Dism says the image version is 6.2.9200.16384

Dism fails with error 0x800f081f

Any ideas how to solve this?

Thank you / Patrik
