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

  • Question

  • 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.

  • Might ask them in powerbuilder forums and over here.

  • Thanks. It's not really a PowerBuilder problem, but I wasn't sure which Microsoft forum was most appropriate. I'll give that one a try.

    Actually, I just discovered this one, which probably fits best:

  • OK, it turns out you were right. This is actually a PowerBuilder problem, and has nothing to do with MSXML. It turns out the error comes up earlier in the code than I originally thought. Apparently the API for urlmon.dll has changed in Windows 8, but it's not MSXML that's calling it.

  • OK, this actually turns out to be a problem with IE10. In Windows 8, the urlmon.dll API has apparently been changed. In the preview version of IE10 that I just installed on Windows 7, the error message instead complains about WININET.dll.

    What forum should I use to complain about these DLLs not being backwards compatible?

  • I'd try over here as well as the IE dev forum.

  • Thanks. Since it's an issue with the IE 10 product itself, this looks like the appropriate place to report issues:
