So you see that the HTML5 Workspace App updates pretty regularly. That’s a great thing! How about you may have several StoreFront servers. You want to do that manually EVERY time? Of course not! Here is a script that will do that for you! You will also need to go get this function from github that makes this work. The piece of resistance one could say! It lets you get the file version details metadata.

While trying to figure out how to target the HTML5 Workspace App version, I did not see it in registry or in Add/Remove Programs. So I was checking the location of the files to see what I could find. I ended up checking C:\Program Files\Citrix\Receiver StoreFront\HTML5Client and found a file SRI.js that had citrixHTML5Launcher version. I figured I could just check that file and get the version number as it reflected the correct version I had installed previously. I did an upgrade to check if that showed the correct version after the upgrade, and it did. Also found out that once you install it, you cannot go to an earlier version, so be sure to snapshot if you want to do some testing with versions.

Here is the link to the function by Lukas Wohrl that allowed me to get the file version from install file. Get-FileMetaData

Below is the script to do the upgrade:

# Script to check version of CitrixHTML5Client on StoreFront servers, copy upgrade file to upgrade folder, install upgrade, based on version detected.
# You will need the function Get-FileMetaData from This allows you to get the file version and convert to
# [System.Version] type to compare. You will also need to have access to the StoreFront servers as admin to be able run invoke commands and if you need to snapshot, access to your hypervisor. Format for txt file is server.fqdn.
