When I try to install the next version of the software I get as far as "Registering Add-in Express for Microsoft Office and .NET..." and it throws the following error:

"Method 'Execute' in type 'AddinExpress.Wizard.ADXWizard' from assembly 'AddinExpress.Wizard, Version=10.0.4700.0, Culture=neutral, PublicKeyToken=4416dd98f0861965' does not have an implementation.

How do I get past this?

It's worse than I thought. After failing to install version 10.0.4700.0 I tried to reinstall the version version 9.5.4661.0 I had been on before trying to upgrade and that I uninstalled successfully beforehand.

This now fails with a similar error
Could not load type 'AddinExpress.MSO.ADXAddinModule' from assembly 'Installer.2005, version=9.5.4661.0, Culture=neutral, PublicKeyToken=4416dd98f0861965'

So now I'm stuck in limbo with no way forward OR back. I uninstalled the version 9.5.4661.0 I was on, but now I cannot install *any* version.

I don't know whether this is going to help at all but my machine was updated to Windows 11 after I installed the previous version. Please, folks, I need to work on our add-ins.

Hello Pino,

To solve the first problem, try the download links at the bottom of this page:
https://www.add-in-express.com/forum/read.php?SHOWALL_1=1&FID=5&TID=16286#nav_start

I suppose the second problem is caused by your antivirus software. Try to turn it off for a while. When installing Add-in Express follow the suggestions below.

Please follow the suggestions below:

Close all Visual Studio instances and make sure there's no devenv.exe processes hanging in the Processes tab of the Task Manager window before you start the installer.
Make sure you are an administrator on the PC.

Set UAC to its default level (you may be required to restart the machine).

Remove the following registry key, if it exists:
HKEY_CURRENT_USER\Software\Add-in Express\{product identifier} {version} {package}
Run setup.exe (not .MSI!) by right clicking it and choosing ?Â?Ð?ìRun as administrator?Â?Ð?í in the context menu.
If you run in an issue, restart your machine and run the installer anew.
Issues where the installer reports files missing can be solved by turning your antivirus software off for a while.
If the issue persists, capture a video showing all installation steps and send it to the support email address.

With thanks to Andrei and the link posted I got it to work.

I was only able to install the software for VS2022, not for VS2019 AND VS2022, but I was actually only using VS2019 because my older version of Add-in Express was installed for that version, so with the new version being installed for VS2022 I don't need it anymore.

The only minor glitch after following the instructions in the link with regard to cleaning up the GAC was that after I managed to install the software and I tried to register the Add-ins I created, an error was thrown about it not finding the AddinExpress.MSO file. That turned out to be caused by it not copying that file local in the references, so once I changed that it all came good.
