OK, i am trying to run a program for WEST at home and every time i try to download the viewer a security warning pops up. it say

--------------------------------------------------------------------------

Windows has found a problem with this file.

Name: hostexpress.cab

Publisher: Unknown Publisher


This file was blocked because it does not have a valid digital signature that verifies its publisher. What is a digital signature?

--------------------------------------------------------------------------

I would like to know if there is any way to disably this or get around it so that i can download the programs i need to do my Job. Thank you for any help you provide.

A quick, practical add-on: the pop-up you posted means Internet Explorer/Windows refused an unsigned CAB (an ActiveX/control package) because it could not verify the publisher. That protection is intentional — unsigned code can run with your user rights and may be malicious. Do not turn off system-wide security without first verifying the file's source.

is right that the browser zone settings affect downloads, and 's driver-signing tip applies to kernel drivers (Device Install signing) rather than CAB/ActiveX content. 's question about "digital signature" is on point: a code-signature ties a publisher identity to a file using a certificate and lets Windows/IE confirm who published the code.

Safe steps to get the software if IT verifies it:

  • Ask your employer/IT for a signed installer, an alternate (non-ActiveX) package, or a published hash (MD5/SHA1/SHA256) you can verify after download.
  • Prefer adding the vendor site to IE's Trusted Sites and temporarily lowering only the ActiveX download prompts for that zone: Tools → Internet Options → Security → Trusted sites → Sites (add URL) → Custom level → set "Download unsigned ActiveX controls" to Prompt (not Enable), allow running only after you get a prompt. After install, restore defaults and remove the site.
  • If you must inspect the CAB first, save it to disk, scan with up-to-date antivirus, and (advanced) extract to inspect contents (for example, using the command-line expand tool) before running anything.

If you are unsure or cannot get a signed package, have IT install it for you or provide a vetted installer. Bypassing browser or signing checks permanently exposes the machine — avoid global disables and revert any temporary changes immediately after the install.

In your browser. Go to options. Internet options. Security. Set to default. Also your firewall may be set wrong. If worse comes to worse disable for the download. Hope that helps.

Right click My computer --> properties --> hardware --> driver signing --> set it to Warn. .... This should work if you're downloading some driver.
