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. Otherwise, Citrix recommends that you wait for the next hotfix rollup pack for your product release. 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.

Where to Find Documentation

New Fixes in This Release

1. EdgeSight reports on published application launch counts can show fewer launches than the actual numbers. This happens as a result of application launches triggered by other published applications such as scripts and commands. Such launches can intermittently fail to be captured.

   This fix resolves the issue in most scenarios. Additionally, consider installing a XenApp hotfix that contains Fix #LA0572. Fix #LA0572 addresses this issue specifically in scenarios with short-lived sessions (sessions shorter than 5 seconds).

   [From XAE500R01W2K8X64040][#LA0066]

2. Application launches can fail to be captured in the case of applications where the published executable exits within a few moments of the launch.

   Note: To address this issue in its entirety, you must install a hotfix that contains Fix #LA0066 before installing this fix. Fix #LA0066 is available as a EUEM hotfix (for Presentation Server and XenApp for Windows Server 2003) and as a XenApp hotfix (for Windows Server 2008).

Fixes from Replaced Hotfixes

1. EdgeSight does not properly collect data for published desktop launches and does not properly display such data in its reports.

   [From XAE500R01W2K8X64023][#240414]

2. The Wfshell.exe process might cause CPU consumption to rise and remain above 25 percent.
