Just require overwrite file without uninstall previous files

[danieltan]

Hi,

Let say, I have two installer which version are 1.0.0 and 1.0.1. As version 1.0.0 first installer for new customer while version 1.0.1 serves as upgrade installer.
My doubt on below (especially install version 1.0.1)
1. After install version 1.0.1, can I ask bypass/do not want uninstall previous files installed in version 1.0.0 and just serve purpose for replace same files?
2. Directly do not require to display "Previous Version uninstallation" dialog and require jump into display "startinstallation" dialog possible? whereby installer version 1.0.0 already predefined the installation path and setting?

Dear Daniel,

if you are delivering a full product update of a based MSI setup, the already installed version have to be first removed. There is no way to skip this behavior.

Alternatively, you may consider to delivery a patch.
