Windows 8 - The procedure entry point AppCacheCloseHandle could not be located in the dynamic link library C:\Windows\SYSTEM32\urlmon.dll


  • I have an application developed with PowerBuilder that uses a COM connection to Msxml2.XMLHTTP.3.0 for sending and receiving data through HTTPS. It has worked great until now, but clients using Windows 8 are getting this error message. I have been unable to find anything about MSXML related directly to any changes with Windows 8 or this error message.

    I'm guessing MSXML uses urlmon.dll, but something has changed in Windows 8?

  • Nevermind - it's not MSXML that's calling urlmon.dll after all. This error actually comes up earlier in the code. This is a PowerBuilder issue, not an MSXML issue.
