Silent Uninstalls

We occasionally get asked by our larger clients if there's an easy way to uninstall Virtual TimeClock when upgrading so they don't have to physically touch each computer. Here are some command line parameters that you may find helpful when scripting silent uninstalls.

The uninstaller program (unins000.exe) accepts the following command line parameters.

/SILENT, /VERYSILENT
The uninstaller will not ask the user for startup confirmation or display a message stating that uninstall is complete. Shared files that are no longer in use are deleted automatically without prompting. Any critical error messages will still be shown on the screen. When '/VERYSILENT' is used, the uninstallation progress window is not displayed.

/SUPPRESSMSGBOXES
Instructs the uninstaller to suppress message boxes. Only has an effect when combined with '/SILENT' and '/VERYSILENT'.

/LOG
Causes Uninstall to create a log file in the user's TEMP directory detailing file uninstallation and actions taken during the uninstallation process. The log file is created with a unique name based on the current date. It will not overwrite or append to existing files.
