Known issues

Issue 1

After you install the .NET Framework 3.5 SP1 in Windows XP or Windows Server 2003, there is an arbitrary folder that is generated in the root of drive C. This folder contains two subfolders that are named amd64 and i386. These two subfolders both include the following files:
  • Filterpipelineprintproc.dll
  • Msxpsdrv.cat
  • Msxpsdrv.inf
  • Msxpsinc.gpd
  • Msxpsinc.ppd
  • Mxdwdrv.dll
  • Xpssvcs.dll
These files were pending to be deleted from the XPSEPSC installation.

Resolution

To resolve this issue, delete the folder manually.

Issue 2

.NET Framework assistant for Firefox has the Uninstall button disabled. In the .NET Framework 3.5 SP1, the .NET Framework Assistant enables Firefox to use the ClickOnce technology that is included in the .NET Framework. The .NET Framework Assistant is added at the computer level so that its functionality can be used by all users at the computer level instead of at the user level. Therefore, the Uninstall button is unavailable in the Firefox Add-ons menu because standard users are not permitted to uninstall computer level components.

Resolution

An update has been produced to resolve this issue and make this version of the .NET Framework Assistant for Firefox compatible with the next version of the Firefox browser. For more information, click the following article number to view the article in the Microsoft Knowledge Base:
