CTX130357 – Java Runtime Environment (JRE) Does Not Appear to be Isolated When Streamed in 64-Bit Environments – Citrix Knowledge Center

Symptoms

Java Runtime Environment (JRE) does not appear to be isolated when streamed in 64-bit environments. It works for administrators but not for users.

Cause

There is a permission error accessing the user’s Classes registry key within isolation. The registry key needs access permission to start JRE and fails to load for users. The current version of Java (JRE 6 Update 26), at the time this article was published, stores the FTA information in a different location, which the user has access to under isolation.

Resolution 1

Add the following redirect rule for the _Classes key under isolation:

Redirect HKU%AIE_USERSID%_classes to HKLMSoftwarewow6432nodeclasses

1. Open the package to be updated with the Citrix Streaming Profiler.
2. Expand the package, right-click on the target and select properties.
3. From the menu on the left, select Rules.
4. Select Add on the right hand side to add a new rule.
5. Select Redirect for Action, Registry Entries for Object and click Next, as displayed in the following screen-shot:

1. On the Select Objects page enter the following information and click next, as displayed in the following screen shot:

• Source Registry Entry

Hive = HKU

Key = %AIE_USERSID%_classes

• Destination Registry Entry

Hive = HKLM

Key = Softwarewow6432nodeclasses

1. Type a name for the new rule and click Finish.
2. Save the Profile
