Hi all, I am trying to make an installation package of a program in Studio 2005. There is a datafile that I want to be installed the first time. However, when re-installing or when installing a newer version, this file must not be overwritten. How can I do this in the condition for this file? Can I somewhere state that the file should only be written if it does not yet exist? Secondly: When I am trying to re-install the software, the installer will refuse, since the same version has already been installed. Can I set an option somewhere to enable re-installations (or to have the installer ask the user if the existing installation should be oberwritten) Thanks in advance for any comments. Regards, William
