I am trying to reinstall the software for my mouse which is a Perixx MX 2000 11. The problem is it won't create a folder in Program files (x86) which is the folder it's telling me it will install the software to. When I try to reinstall this software I also get a message saying that the driver is already installed and that I will have to uninstall first. When I try to uninstall like it says, it then tells me there are something left over that the uninstall didn't delete. I'm stumped not knowing what has been left over though because it doesn't say. I have tried Revo uninstaller, deleting left overs using Regedit, by serching Perixx, but it just seems I can't fully uninstall the mouse software or reinstall it so that it CREATES a folder on Program (x86). I also know it's not fully uninstalled from a previous install, because there is a screen that flashes up as soon as I boot my computer and I see that it is the Perixx software screen.

I have tried this on another Windows 10 machine and a folder is created, so I know there's a problem somewhere. Both PC's are Windows 10. I did have it working on the problem computer at one stage, the only reason it stopped working on this computer is that I was going to buy another mouse, so I uninstalled the software. I then decided later I would keep this mouse and now I'm trying to reinstall this software. I also tried creating a folder on a different HDD when installing just to see if it would atleast create a folder, but it won't even create an install folder on a different HDD. I would go with your gut feeling about a new mouse...i agree another mouse would CERTAINLY narrow down the possibilities.. and also be aware of the customisation VALUES that can be changed in the software that COMES with the mouse.

i looked in the main settings to make my own custom changes which i occasionally forget when changing to a different game. main setting > click any of the 6 drop down menus listed on the left. they open values for all types of clicking, single click, double click, etc. this may need checking out. 

also, administrative privileges. R/click to gain ADMIN privileges. lastly, any untowrd issue may indicate an infection. run a scan with the AV to be sure.
