"Windows can't open Add Printer" error in a 64-bit version of Win7 or of Windows Server 2008 R2

Symptoms

Consider the following scenario:

  • You have a computer that is running a 64-bit version of Windows 7 or of Windows Server 2008 R2.

  • You try to open the Add Printer wizard by using the 32-bit Printui.exe that is located in the %windir%\SysWOW64 folder or by using the rundll32 printui.dll,PrintUIEntry command on the computer.

In this scenario, you receive the following error message:

Windows can't open Add Printer. Operation could not be completed (error 0x0000007e).


Additionally, the computer may stop responding if you use the rundll32 printui.dll,PrintUIEntry command together with the/o, /p, /s, or /e switch.

Cause

This issue occurs because the Printui.dll file calls the 32-bit Tcpmonui.dll file that is not located in the %windir%\SysWOW64 folder.
