Issue: When an application is unable to load because the cache is full, you may receive the following error: Could not connect to stream URL
Error code: 4504B4-16D10E0A-0000E029
Cause: Although the error code that appears in the customer-facing dialog box is incorrect, the correct error code appears in the log as 0000E029.
Resolution: The resolution is probably obvious but I'll go ahead and say it anyway.  You either need to remove apps that are locked in the cache or make the cache larger.  This is also set under the Properties of 'Application Virtualization' on the client.
