After Hotfix - Game won't launch.

[Achelous]

I have tried all of the recent fixes from November and December.

Running as admin, verifying, closing in specific sequences, then re opening in another. etc.

I have updated to windows 11 from 10. And then back to 10. Did not work on either.

What happens:
I open steam, I click Anno 1800, I press "play" (green) it changes to "stop" (blue) confirming it is running the .exe it then turns back to "play" and my Nvidia Geforce Experience then says items restored basically confirming it has stopping running before any program even launches.

I am currently trialling a reinstall of the game.

I was not able to get the Steam to link with Ubisoft Connect. This is how I got Anno to start.

Make sure Anno1800.exe is not marked as Run as Administrator

1. Start Steam by Run as Administrator
2. Start Ubisoft Connect by Run as Administrator
3. Start Anno 1800 in Steam
4. Switch over to Ubisoft Connect and I was asked to link my game.
5. Play Anno 1800

After linking the Steam and Ubisoft Connect.

To get the game to start again...

1. Start Steam by Run as Administrator
2. Start Ubisoft Connect by Run as Administrator
3. Start Anno 1800 in Steam
4. Play Anno 1800

Yeah I tried this as well. I was still unable to get it to work. Even with the new hotfix and verifying and unmarking run as admin as dev's have suggested.

@Achelous are you using Citrix?

Tried deleting it and the game just works now and no other problems.
Thanks for that tried everything weird that this is the issue.

[Nikhil]

Thanks for clarifying Dutch. I can't delete Citrix as I need it for work.

Is there a way of disabling Citrix temporarily?

[Nikhil]

I followed your advice Dutch and uninstalled Citrix.

Anno now runs fine for me - thanks very much.

Never had problems with Citrix and Anno 1800 before. Trouble only started when the latest re-release update came out for Anno.

But I've seen Citrix and the Unity Engine not work well together in the past. Temporarily disabling the "Citrix Virtual Bus Enumerator" in Windows' device manager always did the trick for me without having to actually uninstall Citrix. With Anno, this so far didn't make a difference. Though as I said - I never had problems with Anno and Citrix before.

Same - I've also experienced the Unity Engine issue with Citrix. I actually have left "Citrix Virtual Bus Enumerator" disabled. Unfortunately - as you said - its made no difference to Anno.

This is the fix ladies and gentlemen. Needs to be uninstalled and not just quit or closed. Or force closed.

I uninstalled it. For those that don't know how, just type in the windows bar, Add or remove. Then search Citrix, uninstall it. It will ask to restart your PC. Do this. And then it will run like normal. It will ask to open Ubisoft etc.

I don't know if this is important but to be sure. I unlinked my steam and ubisoft prior to doing this. Just incase.

Anno is not using Unity but Snowdrop. Same engine as the Division 2 and the upcoming settlers game.

@Nikhil, thanks, Deleting Citrix did the trick for me too!

@Nikhil

I have read that if you reinstall Citrix it shouldnt be a problem anymore, but i don't know if thats actually the case.
I have not tested this out yet so, but maybe ubisoft can see this and check whatever is causing this issue to have a perm fix to it instead of uninstalling citrix everytime and hope to god it works.
Its just weird that a workspace app is causing something to not start a game i never had this issue before atleast so maybe something with a new patch from citrix is causing this.

Never claimed it does. It was just an example of where I've encountered actual problems between Citrix and games.

Have also been asking myself what the hell Citrix is doing that might interfere with a videogame.

Unfortunately I can't update Citrix (straightforwardly) as the version of it I use is an old version that comes bundled with my employer's specific SentryBay Armored Client install.

The version of Citrix I'm using is from 2019, so I believe it is Anno's GU16 that is causing the issue.

I've been messing around with the Services in MSConfig, and it may sound obvious but I can get Anno to work if I disable the Citrix & in my specific case the SentryBay services. I don't want to tinker with MSConfig every time I want to play though so this isn't a solution.

[Nikhil]

Apparently (from the German Anno forums) an add-on component of Citrix called "App Protection" might be interfering with Anno. This is an optional feature of Citrix (included in 2019) that allows Citrix to have anti-screenshot and anti-key logging features.

On their website CItrix states that "App Protection" is off by default, and can be activated on installation.

The person from the German Anno forums reportedly reinstalled Citrix with "App-protection" disabled and found that they were then able to launch Anno fine.

I haven't been able to test this as I can't modify my Citrix installation.
