When getting the latest update (I guess from 0.45.x to 0.46.x) the installer is failing everytime, using Windows 11.
I retryed it several time, without any success.
When I finally abort the update, I get the following error message:
Here are the last lines of the named log file:

In Windows programms I do have two “Cursor” apps listed now:
But as soon as this failed update happens, I can not launch the Cursor app anymore!
I do have to install it again. And everytime I close it (later), the next update process will be started, leading to a broken installation as reported. 
I’ve already checked my anti virus for some quarantained cursor files, but there is nothing.
I also can see, that there are some other guys struggling - see the comments of this thread: [SOLVED] Failed Cursor Second update for the day. Unable to Reinstall
Please urgently provide a fix!
Thanks for some help and hopefully a fix!
