Having Problems downloading ica32web.msi?

I have been struggling with an issue for a while on our external Citrix portals (WI 4.6 / CSG 3.0) where the ica32web.msi file will not download for IE clients. Firefox would download just fine while IE would get the following error:

[Window Title]
Windows Internet Explorer

Internet Explorer cannot download ica32web.msi from

Internet Explorer was not able to open this Internet site. The requested site is either unavailable or cannot be found. Please try again later.


After trying just about everything short of a full IIS/WI/CSG reinstall, I finally found the solution.

  • Open IIS Admin
  • Browse to your WI site, then down to AccessPlatform then Clients_common
  • View the Properties of the Clients_common folder

  • Click on the HTTP Headers Tab
  • Uncheck Enable Content Expiration

Now you will find your ica32web.msi file downloads in IE without issues.
