Hi Matt,
Thank you for contacting Octopus Support.
After checking, it looks like we may not be shipping 32bit tentacle installers in 2020.4.X+ versions of Octopus Server. In order to update the tentacle remotely, you’ll likely need to create a Project/Runbook to handle 32bit OS tentacle upgrades.
I would recommend using chocolatey on the tentacle to do this. There is a community step template available that takes care of chocolatey:
https://library.octopus.com/step-templates/c364b0a5-a0b7-48f8-a1a4-35e9f54a82d3/actiontemplate-chocolatey-ensure-installed
After that, you can run the tentacle installer via Powershell, be sure to use -y for silent install:
choco install octopusdeploy.tentacle -y
(The chocolatey .PS1 script shows that it has both the 32bit and 64bit installers)
I tested this as a Runbook. See the following example:
Step 1 - Chocolatey Step Template:
Step 2 - Install Tentacle:
You may need to select individual deployment targets, you may do so via the Show Advanced button:
Then you may use the “Include specific deployment targets” option:
Hopefully that all makes sense. Let me know if it looks like this will work in your case.
Regards,
Donny
