Uninstalling the software
In the documentation for the software https://docs.tier2tickets.com/content/general/installation/, it specifically states to use "wmic product where (name="Helpdesk Button") call uninstall /nointeractive". This is not a good method to use to uninstall the software. Due to the way Microsoft implemented this wmic hook, it causes the Windows Installer service to perform a full verification of all installed software and an automatic repair of any software that fails validation. (Just check your application event logs after using any "wmic product" function.) For certain applications, this can cause the program and configuration to become corrupted.
Instead, the documentation should instruct administrators to use the uninstall command directly as in '"C:\Program Files (x86)\Helpdesk Button\unins000.exe" /SILENT' for the silent uninstall as listed in the program's uninstall string in the registry. In a batch script, it would be '"%programfiles(x86)%\Helpdesk Button\unins000.exe" /SILENT' for 64bit systems and '"%programfiles%\Helpdesk Button\unins000.exe" /SILENT' for 32bit systems.
For a full script it would be:
IF EXIST "%PROGRAMFILES(X86)%" (GOTO 64BIT) ELSE (GOTO 32BIT)
"%PROGRAMFILES%\Helpdesk Button\unins000.exe" /SILENT
"%PROGRAMFILES(x86)%\Helpdesk Button\unins000.exe" /SILENT
This is what should be recommended to use in the documentation, not WMIC product.
