Have you tried running the install script using a run as administrator or elevated PS prompt? Something like belwo: param($program) $sa=new-object -com shell.application $sa.ShellExecute($program,"$args","","runas") Example Start-ElevatedProcess cmd /k ifmember /list

hi if have test the batchfile with run as administrator - same problem same question "can't verify the publisher...."

Try the following settings to enable unsigned drivers to be installed with such a script. 1. Go to Run > cmd and Run As Administrator on the Command Prompt. 2. Key in bcdedit.exe -set loadoptions DDISABLE_INTEGRITY_CHECKS 3. Then Key in bcdedit.exe -set TESTSIGNING ON 4. Reboot system. 5. upon reboot ppen gpedit.msc 6. Expand User Configuration> Administrative Templates > System > Driver Installation 7. In the right panel, double click on ‘Code Signing for Device Drivers’. 8. Choose ‘Enabled’ in the window that appears. In the underlying options, choose ‘Ignore’. This disables drivers signing in Windows 7, and now you can install unsigned drivers in Windows 7. 9. Click Apply, OK. Restart your computer to install unsigned drivers. After these setps are completed trying running the script I mentioned earlier, or your own, however you wish to script it.
