Unable to open ESR and IB

Dear Experts,

I am unable to open ESR and IB in the PI portal.

When I click on the link for ESR or IB, I get the message "Unable to download application".

The actual error is "JNLP file truncated after 10k".

Exception

Resolution Steps Tried

I have tried Java versions Java 1.6 update 45, Java 1.6 update 35, Java 1.6 update 21 but none of them have worked.

I have tried setting the JAVA_HOME environment variable but it has not helped.

I have tried deleting the temporary internet files, clearing the browser cache memory, clearing the Java cache memory but none of them worked.

I have tried selecting 'Direct Connection' in JAVA Control Panel -> Network Setting

Any help will be much appreciated.

Thanks in advance.
