Endpoint Configuration Manager application supersedence

Sounds like your detection methods aren't correct. Can you confirm they are both detecting the correct MSI ?

I'm not using an MSI I've downloaded the Citrix Workspace install .exe and I'm calling it with some install switches from a batch file, this is the way the previous app install was done.

The superseded app had this as it's detection:

Detect Receiver.exe in file path:  C:\Program Files (x86)\Citrix\ICA Client\Receiver AND check file version of wfica32.exe in file path:  C:\Program Files (x86)\Citrix\ICA Client

Version of wfica32.exe is set to be greater than or equal to the version that is being installed.

I used the same detection mechanism for my app and just updated the version of wfica32.exe.

What seems to be happening is this:

1. new app is deployed to the client
2. new app does its install and uninstalls the previous app version
3. In Software Centre both versions of the Workspace app are now listed as installed (even though the previous app is no longer on the machine)
4. The new install prompts for a reboot which I do.
5. After the reboot Software Centre still thinks both apps are installed so I force a config manager update
6. The uninstall script of the superseded app is called (not sure why that is), this then removes whatever version of Citrix Workspace is installed (which in this case is the new version)
7. The new version of Citrix Workspace has now been uninstalled which means there is now no version of Citrix Workspace on the client
8. In Software Centre it thinks that the previous version is now removed and thinks the new version is installed.

I have tried modifying the uninstall script of the superseded app to only run if it detects the superseded version of wfica32.exe.  Now when I force a Config manager policy update the superseded app uninstall script is still invoked but this time doesn't remove the newly installed Workspace and disappears for Software Centre, but the status of the new app in Software Centre is "past due - will be updated"

I have also tried unticking the 'uninstall' option on the supersedance tab, but that means some reg keys from the superseded app version get left behind and I need those removed.

yer, so if your using = or greater than - your going to get yourself into a loop when upgrading - as its always going to matchy on the superseded app - as its always going to be greater than.

Change that to be equal to, rather than equal or greater.

Should i change it to to 'equal to' on both the superseded app and the new one?

I've changed both apps so that file version is equal to, unfortunately it hasn't fixed it and I'm seeing the same behaviour.  I also removed the first detection clause (i.e. checking to see if Receiver.exe exists) just in case that detection clause was causing problems but again it hasn't helped.

Slight correction to one of my earlier posts, the new app shows as 'past due - will be retried' not sure why Software Centre doesn't think it is installed.  I'm seeing this in the AppEnforce log on the client machine.

there is a lag between updating the app and when the new detection rule will be in use.

could you please post the appdiscovery.log and appenforce.log from a machine with the issue.

Hi, please see attached, thanks.

Hi just wondering if you had a chance to look at the log files?

That's great, narrows it down for me a bit, I'll see if I can modify the detection rule in Config manager.

Hi Hayes, I changed the detection method to check the version of Receiver.exe and the install seems to be working fine now.  

Thanks for your help!
