Steps:

  1. Logon to the Controller application server as an administrator
  2. Launch Windows Explorer, and right-click on "Computer"
  3. Choose "Properties"
  4. Choose "Advanced System Settings"
  5. Inside the tab "Advanced" click "Environment Variables"
  6. Inside the section "System Variables" check that there is an entry for "CCR_JAVA_Home"
  7. Check that the 'value' is correct (no typos). TIP: By default, this is: C:\Program Files (x86)\IBM\java60\jre
  8. Restart the Windows services "IBM Cognos Controller Java Proxy".
