Question about Loupedeck +

I have now done it and hope to be able to help you with the following contribution.

I have a separate user with admin rights on my PC. My assumption is that when the installation runs with the separate admin user after password entry, the plugin is not installed in the %appdata% of the user who performed the installation, but in the %appdata% of the admin user. To solve this problem, you can either copy the plug-in from the %appdata% of the admin user or give the user admin rights and install the software again.

The copying is done as follows:
1. open the folder %appdata%\Adobe\Lightroom\Modules in the explorer (%appdata% is resolved to C:/Users/Admin/Appdata/Roaming for me as admin).
2. copy the folder "loupedeck2.lrplugin" to a place where the normal user account has access. In my case this was the D drive:
3. log out as admin and log in as normal user
4. copy the folder to %appdata%\Adobe\Lightroom\Modules
5. start Lightroom
6. click on File > Add-on Module Manager and there on "Add
7. go to the folder %appdata%\Adobe\Lightroom\Modules and double click on the folder "loupedeck2.lrplugin
Start the Loupedeck software if it is not already running. 9.
9. plug in the Loupedeck
10. all buttons will work in the latest Lightroom version.

I have the same problem. I have now written to the support team. The Lightroom plug-in is missing for me. According to the support page, it should install a Lightroom plug-in called Loupedeck2. If this is missing, you should contact support. Only keys like arrows, full screen and C5 for 1to1 zoom work. Just think of these with keyboard shortcuts that don't need the SFK.

I have reinstalled Loupedeck and also downgraded Lightroom to 7.5 without success. Let's wait and see what the support says. Otherwise I will report it here.

I have installed Aurora HDR 2019 on my MacBook Pro and it runs perfectly.

Have you already tried other USB ports?
