So I did not realize (forgot) that I had SDK V5.4.... installed.
I restarted my PC and I uninstalled that but got the exact same error when trying to install.
I have W7 and VS2013 (latest everything in general). I am running "SitefinityTrialSetup_2014.04.exe" V184.108.40.206. Original filename 7zS.sfx.exe
I cannot think of anything else.
