We've installed DNN 6.1.5 on a Dev box - and have moved it to a new QA server. However, we are getting the error "could not load file or assembly system.core version=126.96.36.199"
This must have something to do with the configuration of the server - has anyone come across this error before ?
The 64 bit version of the .Net Framework version 3.5 is installed on the server.
Thansk in advance.
