Re: sims3 installation error Microsoft wse 3.0 x509 certificate tool failure

I still need help here.

I tried removing .NET 4.5.  This left me with .NET 3.5.

I tried installing Sims 3 - same WSE error.

I don't know if I can remove the .NET 3.5 - it doesn't have an entry in the Control Panel - Programs, so I assume its built in the Win7.

I then re-installed .NET 4.5, again tried installing Sims 3, and again got the WSE error.

What can I do to solve this?!
