Having this issue today. What the heck...this has been going on for 2 years??

I'm having the same issue. I have purchased the creative console which I fear will be useless without any login capability working as I work across devices. What a waste of time and money. Come on logitech fix it!

Please keep in mind that I am not an admin user on this device so I am unable to do more than restart the app if there is an issue.

The batch file ran but did not solve the issue.

Still having the issue.

I click on the head and shoulders icon on Logi Options+ app.

Login pops up in a browser window.

I use my Google to login (That's how mu logitech account is registered)

A window pops up saying, " Launching..." etc. and "If your application does not launch, please press the button below."

Pressing the button does nothing.

I have this issue on my work PC. I can't log in to create or modify smart actions.

I have the same issue on my business Laptop.
The comment from @edgard did also not fix the issue

The issue being addressed involves a custom URL scheme used by Logi Options+ software, specifically for Logitech devices. This scheme allows a web browser to communicate with the Logi Options+ application installed on your computer. However, if the scheme is not correctly registered in the Windows Registry, the browser will not know how to handle it, leading to the error message seen when attempting to use the app.

To resolve this, we need to properly register the custom URL scheme (`com.logitech.logioptionsplus`) in the Windows Registry. This registration tells Windows how to handle URLs that start with `com.logitech.logioptionsplus://`, by directing them to the Logi Options+ Agent executable. The following batch file script does exactly that:

```batch
@echo off
SETLOCAL ENABLEEXTENSIONS
SET keyname=HKEY_CLASSES_ROOT\com.logitech.logioptionsplus
SET value=

REG ADD "%keyname%" /f
REG ADD "%keyname%" /ve /t REG_SZ /d "URL:com.logitech.logioptionsplus" /f
REG ADD "%keyname%" /v "URL Protocol" /t REG_SZ /d "" /f
REG ADD "%keyname%\shell" /f
REG ADD "%keyname%\shell\open" /f
REG ADD "%keyname%\shell\open\command" /ve /t REG_SZ /d "\"C:\Program Files\LogiOptionsPlus\logioptionsplus_agent.exe\" \"%1\"" /f

ENDLOCAL
```

This script creates the necessary registry keys and values. Specifically, it:

1. Adds a registry key for `com.logitech.logioptionsplus`.
2. Defines this key as a URL protocol.
3. Specifies the command to run when this URL protocol is invoked, which is to execute `logioptionsplus_agent.exe` with the URL passed as a parameter.

To use this script, follow these steps:

1. Copy the script into a text editor like Notepad.
2. Save the file with a `.bat` extension, for example, `RegisterLogiOptionsPlusProtocol.bat`.
3. Right-click on the saved file and select "Run as administrator".

Running this script will modify the Windows Registry to correctly associate the `com.logitech.logioptionsplus` URL scheme with the Logi Options+ Agent application, resolving the issue where the browser fails to launch the application. As always, caution is advised when modifying the Windows Registry. If unsure, it's best to seek assistance from a professional or contact Logitech support for guidance.
