>>Does an .msi installer exists for Eraser 5.7
It did and we were nearly wiped off the map with support calls.
The current version in Beta (see announcement) has a silent install option.
Instructs Setup not to reboot even if it's necessary.
Prevents the user from cancelling during the installation process, by disabling the Cancel button and ignoring clicks on the close button. Useful along with '/SILENT' or '/VERYSILENT'.
Disables the This will install... Do you wish to continue? prompt at the beginning of Setup.
Instructs Setup to be silent or very silent. When Setup is silent the wizard and the background window are not displayed but the installation progress window is. When a setup is very silent this installation progress window is not displayed. Everything else is normal so for example error messages during installation are displayed and the startup prompt is (if you haven't disabled it with DisableStartupPrompt or the '/SP-' command line option explained above)
If a restart is necessary and the '/NORESTART' command isn't used (see below) and Setup is silent, it will display a Reboot now? message box. If it's very silent it will reboot without asking.
