Symptoms
You cannot start an XAML Browser Application (XBAP) that was created by using Windows Presentation Foundation (WPF) in the Microsoft .NET Framework 3.0 or in the Microsoft .NET Framework 3.5. Additionally, if you browse the XBAP in compatible browsers, you may experience one of the following symptoms:
-
A blank browser window may appear. Additionally, a download dialog box appears that never stops downloading.
-
You receive the following error message in the browser:
Deployment Failed
-
You receive an error message that states that the application crashed.
-
The PresentationHost.exe process and the browser may restart repeatedly.
Note Compatible browsers are browsers that support XBAP.
Cause
This problem occurs because of an abnormal condition that is caused in certain account migration scenarios or operating system upgrade scenarios.

Important This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click the following article number to view the article in the Microsoft Knowledge Base:
322756 How to back up and restore the registry in WindowsManually repair the permission settings. To do this, follow these steps:
-
Click Start, click Run, type regedit, and then clickOK.
-
Expand HKEY_CURRENT_USER, and then expandSoftware.
-
Right-click Classes, and then clickPermissions.
-
Under Group or user names, click the affected user account name.
-
Under Permissions forUserName, click to select theAllow check box for the Full Controlpermission.
-
Click Advanced, and then click to select theInclude inheritable permissions from this object's parentcheck box.
-
Click Apply , and then clickOKtwo times.Note If you still cannot start the XBAP, go to step 8.
-
Expand HKEY_CLASSES_ROOT, and then expandInterface.
-
Right-click{79EAC9C9-BAF9-11CE-8C82-00AA004BA90B}, and then clickPermissions.
-
Under Group or user names, click the affected user account name.
-
Under Permissions forUserName, click to select theAllow check box for the Readpermission.
-
Click Apply, and then clickOK.Note If you still cannot start the XBAP, repeat steps 6-7. If the problem is not resolved, follow steps 9-12 for the following registry keys:
-
{79EAC9C1-BAF9-11CE-8C82-00AA004BA90B}
-
{79EAC9C4-BAF9-11CE-8C82-00AA004BA90B}
If the problem is not resolved, go to step 13.
-
-
In Windows Explorer, locate the following path:
C:\Documents and Settings\UserName\Local Settings\
-
Determine whether the following folders under this path contain a file that is named Desktop.ini:
-
The Application Data folder and its Deployment subfolder
-
The Apps folder
-
The Temp folder
-
-
Rename the Desktop.ini file to another name.
-
Locate the folder that contains the Desktop.ini file, right-click the folder, and then click Properties.
-
On the Security tab, clickAdvanced.
-
Click to select the Include inheritable permissions from this object's parent check box.
-
Click Apply, and then clickOK.Note If the problem is not resolved, repeat steps 14-19 for all folders that are listed.
More Information
The PresentationHost.exe process runs with a restricted process token. The process gives up membership in the Administrators security group and in the Power Users security group. The applications that run in the Internet zone sandbox do not have to have the full permission to these security groups. Additionally, the process gives up many Microsoft Windows NT security permissions.This behavior is a defense-in-depth security feature. The effect of this feature resembles how non-elevated processes run on Windows Vista when User Account Control is active.In some account migration scenarios or operating system upgrade scenarios, subtle corruption of Access Control Lists (ACLs) may occur. This corruption causes a particular user account not to be explicitly given access to certain folders or registry keys that belong to the user profile. This problem may occur because permission inheritance on the parent object is disabled. This problem only affects the applications that have the group membership disabled. For example, the PresentationHost.exe application has the group membership disabled.This problem is known to affect the permissions for the following registry keys or folders:
-
The Classes registry key
-
The IPersistMoniker interface registry keys
-
Some folders in the following path:
C:\Documents and Settings\UserName\Local SettingsFor example, the Application Data folder and its Deployment subfolder, the Apps folder, and the Temp folder are affected.
