Silent uninstall
As an alternative to dialog-based uninstall, you can also run a silent uninstall without you having to do anything.
The following call, for example, can be used.
signotec_signoSign2_XX.X.X_64Bit.exe /s /x /v" /qn"
Uninstalling irrevocably deletes the software from the installation directory and all configurations made from the global default directory “C:/ProgramData/signotec/signoSign2.” External or outsourced configuration files and the user-specific settings under “%AppData%/signotec/signoSign2” cannot be deleted by the setup and must be removed manually.
