I'm new in packaging.
I would like to build some packages :

I will use InstallShield 10.5 Professional Edition.
I have to choose between Basic MSI or InstallScript MSI (and anything else ?).
But I don't know if I need InstallScript (InstallShield Help says that InstallScript MSI setups are less desirable to systems administrators because they require the use of Setup.exe :-/ ).
I will have to do some special actions in my setup :
First, I will have to uninstall ALL old versions not MSI-based (InstallShield 6.3). I saw that I'll need "Custom Actions" to do that.
And maybe I will need to reboot, and automatically launch my setup again. (because of locked DLL in windows 2000).
Then I will need, at the end of the installation, to launch a *.bat file (driver installation) and to launch an *.exe file (configuration of the network protocol).
Do you think I will have to select InstallScript MSI, or can I do it with the Basic MSI ?
Thanks !
