Is LayOut open? If so, close it, too.

Probably some process hanging up. Option1 Ctrl+Alt+Delete>Task Manager. Look for any running SketchUp related processes. Right click on them and choose End task.

Option2: Reboot your computer, download the new installer from sketchup.com/download/all, right click on it, choose Run as administrator.

One of Dave’s tips is going to solve the problem. For your interest, Ctrl-Shift-Esc is a faster way to get Task Manager open, and when you have it open click on the More Details link. The culprits are likely to be sketchup_webhelper entries, lower down in the long list of processes.

Similar to @DaveR suggestions;

When I installed maintenance update 2021.0.1, all my applications were closed before beginning the process, however the installer could not proceed (I guessed because of a still running background program).

I canceled the process, Restarted Windows, and then successfully ran the SU installer (per Dave’s instructions), installing SU update successfully.

Excellent, I made it. thank you for all your answers. I close all, restart and all good.
