No longer able to install WSERemoteApp
Hi,
I have Windows Server 2022 Datacenter. I have WSEE installed and I had WSERemoteApp. But recently it was telling me it was not supported. I downloaded the latest version and tried installing it but got a message ‘The add-in cannot be installed on the server.”.
I also started getting the error that WSERemote App is no longer supported when trying to start any program.
So naturally I decided to uninstall the add in and try installing it but ended up having the error.
What do you recommend I do?

Hmm… I’m not exactly sure what’s going on there. Please try the following to see if it resolves the issue for you:
1. Sign in to your Essentials server as an Administrator.
2. Open the following folder on the Essentials server:
C:\ProgramData\Microsoft\Windows Server\Data\addins
NOTE: The ProgramData folder is a hidden system folder, and so you’ll need to enable the viewing of hidden files and folders in order for you to be able to see its contents. That can be done using the “Folder Options” Control Panel applet (via its “View” tab).
3. In the “packages” subfolder, delete the file named “009ef2c9-1a5c-4564-8156-92b85d9d7705.wssx” (if it exists).
4. In the “msi” subfolder, delete the entire subfolder named “009ef2c9-1a5c-4564-8156-92b85d9d7705” (if it exists).
5. Open the following folder on the Essentials server:
C:\ProgramData\Microsoft\Windows Server\Data\settingsproviderdata\WEBSERVICESPLATFORM\ADDINS
6. Look through all of the .xml files that are in that folder until you find the one that corresponds to WSE RemoteApp (just double click on the .xml file to open it in the web browser, or you can open it in any text-based reader app such as Notepad, WordPad, etc. and then search its text contents for “WSE RemoteApp” to know that you’ve located the correct .xml file). Once you’ve located the correct .xml file, go ahead and delete it from your Essentials server (note that you can also delete its corresponding .bak file as well).
NOTE: This simple text-based file contains installation information, etc. about the WSE RemoteApp add-in (such as its version number, etc.). It will be automatically recreated the next time you perform an installation of the add-in.
7. Download the latest release of the WSE RemoteApp Updater from here (as of this writing, the current/minimum release is Version 1.255.2103.0).
8. Run the WSE RemoteApp Updater program from the desktop of the Essentials server.
Does that resolve the issue for you?

Hi Mike,
Thanks for the quick reply. I tried the file deletion then run the latest install and got the same error.
What is interesting is that the files got recreated.
While following your guide I saw a log folder and this is what I see in there after the install:

I’m not seeing much in that log blurb that you posted, and I can’t access your one drive logs. So…
Are you running the WSE RemoteApp Updater from the server, or from one of your connected client computer? If the later, then try running it directly from the server instead.
Is the WSEE Installer on your Windows Server 2022 up-to-date? If not, then download the latest WSEE Updater from here.
If the latest release of WSE RemoteApp still won’t install, then you might want to try completely removing it from your Essentials server, rebooting, and then installing it again. To do so… Open the server Dashboard, go to the “APPLICATIONS” page, select the WSE RemoteApp add-in, and then click on the “Remove the add-in” task. Reboot the server afterwards, and then reinstall WSE RemoteApp via the latest full installer that can be downloaded from here.
Other than that… Take a look in the server’s “Logs” folder to see if any of the logs in there give any additional information as to why the installation is failing. You can find the server’s Logs folder here:
C:\ProgramData\Microsoft\Windows Server\Logs
If you sort the folder by date modified, then the most recently written to log files will appear up at the top of the folder.
You might also want to take a look in the Windows Logs -> Application log of the Event Viewer to see if anything of interest shows up in there as well.
