BUG: "WinHTTP5.dll Could Not Be Found" error message when you run Proxycfg.exe after you install MSXML 4.0 SP2
On This Page
SYMPTOMS
When you install Microsoft XML (MSXML) 4.0 Service Pack 2 (SP2) on a computer that is running Microsoft Windows 2000 Service Pack 1 (SP1) or on a computer that is running Windows 2000 Service Pack 2 (SP2), the Microsoft Windows HTTP Services (WinHTTP) proxy configuration tool (Proxycfg.exe) does not set the WinHTTP proxy
settings, and you receive the following error message:
The dynamic link library WINHTTP5.dll could not be found in the
specified path
C:\WINNT\system32;.;C:\WINNT\system32;C:\WINNT\system;C:\WINNT;C:\WINNT\system32;C:\WINNT;
C:\WINNT\system32\WBEM;C:\Program
Files\ActivCard\ActivCard Gold\resources;C:\Program Files\Microsoft SQL
Server\80\Tools\BINN;C:\PROGRA~1\CA\Common\SCANEN~1;C:\PROGRA~1\CA\eTrust\
ANTIVI~1;C:\WINNT\System32;C:\Program
Files\Cooktop 2.5.
CAUSE
WinHTTP.dll is part of Windows 2000 Service Pack 3 (SP3) and Windows 2000 Service Pack 4 (SP4). WinHTTP5.dll is part of MSXML4.0 SP2. The WinHTTP proxy configuration tool (Proxycfg.exe) is part of MSXML 4.0 SP2. However, it is
not part of Windows 2000 SP3 or Windows 2000 SP4. When MSXML 4.0 SP2 is installed on
a computer that is running Windows 2000 SP1 or Windows 2000 SP2, MSXML 4.0 SP2 installs Proxycfg.exe, but does not install the WinHTTP5.dll component because the WinHTTP.dll component already exists. Proxycfg.exe is installed by using MSXML 4.0 SP2 and is not compatible with
the WinHTTP5.dll component. Therefore, when you run Proxycfg.exe, you receive the error message that is mentioned in the "Symptoms"
section of this article.
