Can you have a look at the http headers the client sends to see if there's anything about the version

Thanks. Yep, will look tomorrow. Not hopefully though....😔

You should be able to upgrade receiver /workspace through the Netscaler as long as you set the deploy receiver/workspace app settings correctly on the receiver for web site in storefront "deployment option = install locally / allow users to download hdx plugin at login then set your source either citrix.com or receiver clients folder on your SF server. check the web.config for pluginAssistant enabled="True" upgradeAtLogin="True" as well. Your other option is rewrite some text onto the NS GW login page with a hyperlink to latest workspace app

@c4rm0 yes, the receiver/workspace upgrade works fine via storefront internally but not when you connect externally via the netscaler. So the settings for web.config, etc should be good. We use a different address externally (remote.company.com) and internally it’s direct (storefront.company.com). Maybe this is the reason the upgrade process doesn’t work? I have already added a link/text to login page for workspace upgrade but users don’t look or understand or can’t be bothered. EPA pre authentication scan just doesn’t work for some reason. Tried a few registry keys for Citrix version but nothing seemed to work. We still use classic expressions maybe it needs advanced expressions?

just knocked that together it looks for the md5 value of receiver.exe that is the md5 of <Workspace version="20.10.0.20">

Thanks Very interesting , I’ll look into that tomorrow. It look like an Advanced expression? I’ve been looking at a registry key on client within HKLM\software\citrix and checking if value >=20.0.25.

it works just tested it EPA fails for anything less than 20.10.0.20

Thanks in advance, really keen to test this tomorrow.
