Windows 7 After several MS updates Kensingston Expert Mouse ceased working, cant install software

[StephenH]

Thank you,
Win 7 64 sp1
I have been using Kensingston's Expert Mouse Model# K64325. After some Windows updates plus installing Silverlight and reboots the mouse ceased working.
Uninstalled the software, reboot. Tried to install the Kensingston software: showed to be for Win 7 64. I would not install.
Unverified signature. error (58).
After trying the uninstall and installing some older software that also was for Win 7 64, the mouse still did not work.
I went back several restore points and tried to install again. Nope.
Uninstalled Silverlight, still Kensingstion Software did not install.
Tested the Expert Mouse in another compter, Win XP Pro Sp2, worked fine.

I am disabled in a way that I have to use my left hand and a track ball. This one is the best, I love it and cant use it.

I know this happened after downloading some updates for Win 7 64. All found automatically by Windows Update.

One of the restarts and that was it, no Expert Mouse.

Your guidance and help are desperately needed.
Thanks,
SephenH

Hello SephenH, I understand the frustration you are facing with your Expert Mouse Model# K64325 not working on your Windows 7 64-bit system after recent updates and installations. The issue you are encountering seems related to the Kensington software installation failing due to an "Unverified signature" error (58). Here are some steps you can take to troubleshoot and potentially resolve this issue:

1. Driver Signature Enforcement:
   • Windows can block the installation of drivers with unsigned signatures, causing the "Unverified signature" error. You can try temporarily disabling driver signature enforcement to see if this allows the Kensington software to be installed.
   • To do this, restart your computer and during the boot process, press F8 to access the Advanced Boot Options menu. From there, choose "Disable Driver Signature Enforcement." This will allow you to install the Kensington software even if it has an unverified signature.
   []Compatibility Mode:
   • You can try installing the Kensington software in compatibility mode. Right-click on the installer, select Properties, go to the Compatibility tab, and choose to run the program in compatibility mode for Windows 7. This may help with installation on your system.
   []Windows Updates:
   • Sometimes Windows updates can cause compatibility issues with certain software or drivers. You can try uninstalling the recent Windows updates that might have caused the problem. Navigate to Control Panel > Programs > Programs and Features > View Installed Updates, and then uninstall the problematic updates.
   []System File Check:
   • Perform a System File Check to scan and repair corrupted system files that might be affecting the installation of the Kensington software. Open a Command Prompt as an administrator and run the command: sfc /scannow.
   []Check Hardware Connection:
   • Ensure that the hardware connections are secure. Try using different USB ports on your computer to see if the mouse is recognized.
   []Alternative Drivers:
   • Look for alternative drivers for the Expert Mouse that may be compatible with Windows 7. Sometimes, generic drivers or other compatible drivers can work with the hardware.
   []Contact Kensington Support:
   • If all else fails, reach out to Kensington support for assistance. They may have specific troubleshooting steps or updated drivers that can resolve the issue. Remember to create a System Restore Point before making any major changes to your system so that you can easily revert if needed. I hope these steps help in resolving the issue with your Expert Mouse on Windows 7. Let me know if you need further assistance.
