I have a customer who does not SWA and we are trying to install the 6.3 SP4 sysadmin 6_3_99_0-SysAd_6_3_8_99-DBP-64bit and the 32bit software and it fails during the diagnostics part stating make sure the .NET 4.0 or greater is installed and turned on, this happen on two laptops and the network admin made sure all the .net is installed as well logged in as a admin.
