What is error message you are seeing?
Trying downloading Net4 framework (as mentioned on blog) and see if it helps.
Regards,
Escape
Dotnet 4 is already there on my system........
Option Oracle does not open at all.
Windows throws error saying that " Option Oracle has stopped working".
Tried on Win 8 and Win 10.
There it it is demanding Dot Net 2 & 3.5.
Win 8 & 10 have Dotnet 4 by default.
Pretty strange behaviour.
