Legacy Update Help

.NET Framework installation issues on Windows XP Embedded

After updating Windows XP Embedded, Windows Embedded for Point of Service (WEPOS) or Windows Fundamentals for Legacy PCs (WinFLP) to Service Pack 3, .NET Framework versions 3.0, 3.5, and 4.0 will fail to install. If you click to open the error log file, you may see the following:

WapUI: [2] DepCheck indicates WIC Installer is not installed.

To fix this, Microsoft provides the following workaround:

  1. Click Start → Run, type cmd, and click OK.
  2. Type the following commands, pressing Enter after each one: cd %windir%\system32 regsvr32 /u wmphoto.dll ren wmphoto.dll wmphoto.dll.old
  3. Close the Command Prompt window.

Installation of .NET Framework should now succeed.
