Hello, All!

I have fought with ZK Studio activation for a few hours, so I want to share found solution with all.

First of all, the environment:
- Eclipse J2EE 3.6 SR2 x64
- ZK 5.0.6
- ZK Studio 1.0.0

How the problem was looked:
I called "ZK Studio Activation" form, typed correct username/password, "Status of Actvation" progress bar appeared BUT no progress had been started and I had to skip process and close form

All Eclipse network parameters are set well - I use remote installations and updates.

In Eclipse log I saw:
"!MESSAGE null
at [org.zkoss.eclipse.services.license.core.LicenseManager]
!STACK 0
java.lang.NullPointerException
at java.lang.String.<init>(String.java:515)
at org.zkoss.eclipse.license.util.LicenseReader.read(Unknown Source)..."

and

"!MESSAGE Unhandled event loop exception
!STACK 0
java.lang.RuntimeException: java.lang.RuntimeException: cannot load any license from environment
at org.zkoss.eclipse.services.ui.ZKRegistrationUIHelper.storeUserProfile(ZKRegistrationUIHelper.java:313)..."

And the solution:
1) locate JRE which is used by Eclipse
2) go to <jre folder>/lib/security, find file java.security
3) in this file the list of security providers is provided, it's elements look like security.provider.<N>=<provider class> where N is just order number
we should add the following provider
security.provider.9=org.bouncycastle.jce.provider.BouncyCastleProvider
9 - it's the next order number in the list
4) copy bcprov-jdk15-143.jar to <jre folder>/lib/ext (you can find this jar inside <eclipse folder>/plugins/org.zkoss.eclipse.services_1.0.0.v201101111416, /lib folder)
5) restart Eclipse and try to activate ZK Studio

Hope it will be helpful!
