Important Note(s) about This Release

• Note: As a best practice, Citrix recommends that you install this and other hotfixes only if you are affected by the specific issues they resolve.

Hotfix rollup packs consolidate most previously released hotfixes and allow you to update systems in a convenient, single installation.
• Important: Installing this hotfix over an ICA session is not supported but you can install it through a remote desktop session using an administrator account.
• Caution! This release may require you to edit the registry. Using Registry Editor incorrectly can cause serious problems that may require you to reinstall your operating system. Citrix cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk.

New Fixes in This Release

1. On systems with Fix #256517 installed, the "Start this application without waiting for printers to be created" printer autocreation policy setting is and remains enabled for all applications. As a result, when printing from an applications, all printers specified under the policy are created.

   [From XAE500R01W2K8X64058][#LA1075]

2. After applying Microsoft article KB2620656, session default printers are not set correctly.

   [From XAE500R01W2K8X64058][#LA1294]

Fixes from Replaced Hotfixes

1. On occasion, published applications wait for printers to be created, even if the "Start this application without waiting for printers to be created" setting is enabled.

   [From XAE500R01W2K8X64017][#247726]

2. This fix addresses the following issues:

   • Corrects a condition where operating system objects associated with printers within a client session can become invalidated and cause printer autocreation to fail
   • Prevents the Citrix Print Manager Service from failing under certain conditions due to a heap corruption

   [From XAE500R01W2K8X64017][#256517]

3. Autocreated printers might fail to fully initialize in the session, causing a "The printer is not installed" error message to appear.

   [From XAE500R01W2K8X64026][#195908]

4. With SmoothRoaming enabled, users must relaunch sessions to reenumerate and update session printers after roaming to a different location. This feature enhancement introduces dynamic printer discovery to automatically reenumerate and update session printers after roaming to a different location so that relaunching of sessions is no longer necessary. To enable this enhancement, you must also deploy a client hotfix that includes Fix #226929.

   [From XAE500R01W2K8X64026][#226929]

5. At times of heavy utilization, the Citrix Print Manager Service (Cpsvc.exe) might fail to release some of its heap blocks.

   [From XAE500R01W2K8X64026][#227962]

6. After upgrading to Hotfix Rollup Pack 1, the Citrix Print Manager Service (CpSvc.exe) might fail intermittently.

   [From XAE500R01W2K8X64026][#260434]

7. The Citrix Print Manager Service (CPsvc.exe) can exit unexpectedly while deleting a user's session printers at logoff. When this happens, session printers fail to be created for newly connected sessions until the service is restarted.

   [From XAE500R01W2K8X64026][#LA0155]

8. A race condition when launching or reconnecting to a session can prevent some session printers from being created.

   [From XAE500R01W2K8X64026][#LA0216]
