During a short search on the Internet I came across a series of hits with error code 0x80190194, but these led to different causes.

  • Update error 0x80190194: Within this Technet forum post the download of updates fails with this error code.
  • Update error 0x80190194: Also this forum post describes an update download failure win SBS 2003 SP1.

What stands error 0x80190194 for?

Error code 0x80190194 could not be decoded in the tools available to me. But there are other ways to find out more about the error code. A very good explanation regarding the decoding of various error codes can be found in this stackoverflow article. It explains that 0x8019nnnn codes stand for HTTP errors. The digits nnnn then indicate the respective http error code. The value 0194 hexadecimal stands for 404 decimal. Thus, error code 0x80190194 means that the requested server has returned HTTP error 404.

The HTTP error 404, however, means ‘page not found’ for web servers. In the Windows context, error code 0x80190194 means that the file was not found on the server. On this web page (deleted) the error code is then also equivalent to HTTP_E_STATUS_NOT_FOUND (with reference to winerror.h).

Possible error causes

When using a WSUS, this simply means that it does not find the files requested by the client. Usually it is a misconfiguration of the WSUS, so that the files are missing. I have also noticed cases where insufficient access rights to a file are cited as the reason for the error. In this older thread, it was a missing Eula file that caused the error.

I have seen hits on the internet where non running services were also the cause for this error message. On Windows clients, I would consider additional software such as third-party antivirus software or proxy software as the cause.
