Cannot install AMD970 drivers

Tried the older v15.20

 

and the most recent (from the AMD Download Page) v17.10

 

BOTH always throw an error stating "Package Manager Install Package Failure!".

 

Well i really would like to install my chipset drivers completely. Yes, in this case its not a GPU problem. its a chipset-driver problem and i really like to know how to solve it the easy way.

 

regards
