Windows has built-in support for five-button mice, but if your mouse has more than five buttons, then you’ll need to install SetPoint to support the extra buttons. But when installing it, I got the warring that 'You are running a 32 bit installer in a 64 bit OS, please run correct installer.' Have no idea where my 32 bit installer is and would like to know how to download and install a 64 bit installer. When to install SetPoint: To assign various functions to your mouse buttons or keyboard, F-keys, and hotkeys. I figure that if I go to Setpoint 6 I might solve the problem. I'm also noting some similar behavior after deleting Setpoint 4.80 and using a regular mouse via USB port. This activity is of course very annoying. Thought this was only happening in M2, but now it has happened elsewhere. Bring the cursor back to the yes, left click, and command is executed. A slight move of the cursor will now cause it to jump about an inch or so at a 45 degree angle to the left. If there is a dropdown with a yes/no choice and I place the cursor on the yes and left click, nothing happens. The most used version is 4.80, with over 98 of all installations currently using this version.

It will skip to the left after being placed on an item. Logitech SetPoint is a program developed by Logitech. The cursor now acts quite strangely., although not every time.just occasionally. I think the update screwed up my Logitech cordless optical trackman (software 4.80).

I recently upgraded my Nvidia software via a Windows update. Need 64 bit installer to install Setpoint 6.0
