OpenCL Code builder doesn't work anymore after upate

[renegr]

I've updated OpenCL SDK and now nothing works anymore. Previously analyzed and working kernels just hang in OpenCL Code builder. With VS2013 plugin I just get Messages that the Connection to the Server failed.

Additionally only OpenCL Code Builder 32bit at least finds the kernels in the program. The 64bit Version refuses everything...

I'm running Win10 64bit

The error message is: No Connection could be made because the target machine actively refused it.

But the application is in the whitelist of the Firewall.

Any ideas?

Edit: I've switched the Firewall off but it didn't help anything. CPU is an I4700

I'm taking a look but so far I'm having difficulty replicating this behavior.  I'm also trying an update to the latest Intel OpenCL on a  4th generation (HSW) processor.  (Assuming you meant i7-4700?)

You may have seen this already, but there is a troubleshooting section in the OpenCL Developer's Guide: https://software.intel.com/en-us/node/539342 which may help.
