This hotfix package fixes the following issues.
Issue 1: Application Virtualization (App-V) clients cause a system crash because of an APC mismatch.
Sometimes, the App-V client generates a system crash together with an asynchronous procedure call (APC) mismatch error. After you apply this hotfix, certain App-V-generated system crashes should be fixed.
Issue 2: Some virtual applications cannot start when the full path is not specified.
When a virtual application creates another virtual process, the virtual relative path is sometimes incorrectly used, and the application does not start. After you apply this hotfix, the correct path is used, and the application starts.
