Based on the experience of our technical support, almost 99% of all problems that you may encounter when using Logitech mice and the official Logitech G HUB software can be solved quite simply, and many of these problems may not affect you at all if you followed our installation guide macros in G HUB.
G HUB stuck at "Loading Localizations"
On the latest versions of G HUB, the most common problem is that localizations take forever to load.

If G HUB is stuck on loading localizations, the first thing you can do is reconnect your mouse (turn it on and off if it’s wireless). If that doesn’t help, open the Task Manager and close all G HUB-related processes, including the G HUB agent, and try restarting G HUB.
G HUB not starting (stuck at loading)
After updating or installing a new version of G HUB, Logitech G HUB may stop launching. Often, you just need to wait, sometimes for quite a long time. If, as it seems to you, the waiting period has been prolonged, in this case, restart your PC, launch G HUB as an administrator, after which G HUB should start (possibly with a short pause, take your time).
It could happen the same way when connecting a new device from Logitech. The situation can be corrected by completely uninstalling the current version of G HUB, rebooting the PC (this is important!) and starting the installation of its latest official version from the administrator.
Macros or Lua scripts doesn't work
- Be sure to check whether you have disabled the “Internal Memory Mode” mode – in this mode no Lua scripts will work.

- If you use our Lua scripts – сheck is whether global macro activation is enabled (in our Lua scripts with macros, CapsLock is usually responsible for this) and whether there is an active macro for any weapon at the moment. Activating a macro for any weapon is accompanied by a message in the G HUB console.
- Make sure your game’s anti-cheat software doesn’t block emulated input generated by G HUB. This can’t be affected by Lua scripts. Currently, G HUB is blocked in FACEIT, VALORANT, and several other games, so A4Tech Bloody mice are required for these games.
- In very rare cases, it happens that after launching some games, macros (Lua scripts) G HUB stops working and this cannot be solved even by restarting the PC. Solution – upload any other macro to G HUB, and then back to the previous one, after which G HUB will start playing macros again.
Right ALT doesn't work
Almost always, this problem is associated with the active keyboard layout and the nuances of how the right ALT works with this layout. Just change the layout to EN and the right ALT will work again and be determined by the G HUB.
G HUB does not detect mouse
If updating G HUB and changing the USB port where the mouse is connected did not help, then check whether your mouse is original from Logitech or not. Most often we come across replicas on the G304 model. Buy Logitech mice only from trusted sellers, as well as macros for them.
If there are no doubts about the authenticity of your mouse, then make sure that you have installed a version of Logitech G HUB that is “familiar” with this mouse, so that everything works for sure – you can simply install the latest version of G HUB.
G HUB file corruption
An error indicating that the program is probably damaged may appear due to a failure to install or update G HUB, as well as if the file system is damaged. The problem is often resolved by the G HUB installer itself, but if this does not happen, then you can reinstall G HUB yourself.
Lua scripts are not imported into G HUB
Are you importing a Lua scripts (macros) but the script window remains blank? Problem with importing and running macros is a common problem with some older versions of Logitech G HUB. You need to update G HUB to the latest official version.
Additional recommendations
Gaming Profiles in Logitech G HUB
Macros may not work when uploaded to G HUB game profiles. Instead, it is better to use the “Desktop” profile assigned as the default profile. We considered this in detail in the guide for installing macros on Logitech G mice.
Be sure to familiarize yourself with the correct installation of macros in Logitech G HUB, this will save you from most of the problems.
Launch G HUB as administrator
It is true that in some situations running Logitech G HUB as an administrator can be a solution.
Reinstall G HUB
- Uninstall G HUB.
- Restart your PC.
- Download the latest version of G HUB from the official Logitech HUB page and install it again.
