I've noticed this on 3 different machines already, all of them had a clean install of RS3 Neither the DOS command nor even installing it from Programs & Features by letting it download works. It just gives an error message that it wasn't able to complete or something any ideas how to fix this?
I use this with no problems hope this helps goodluck INSTALL MICROSOFT .NET FRAMEWORK 3.5 OFFLINE insert Windows disc/usb setup open Command Prompt as Administrator following command Dism /online /enable-feature /featurename:NetFx3 /All /Source:\sources\sxs /LimitAccess Replace Source "D:" it with the correct drive letter according to your system.
I had this problem but after updating windows, I think it was a feature update or something, it then worked.
A feature update would be an upgrade to a new build? That will fix most existing problems, an inplace/repair upgrade would too.
