I am currently trying to make an installer for my company, here are the already done things:
The InstallScript program loads up a DLL, and with this DLL checks user registration on our server.
After registration complete, i need to have some code to dynamically download the installation files from the same server. The protocol is HTTP, and i have already made some functions in the DLL which downloads multiples files onto one big file, then splits the big file onto real files to be installed.
Here is my 1st question:
At the download step, the installer "freezes" until download is complete. Is there a way to make a custom dialog with a progressbar telling the user where the download is?
2nd Question, once the files are downloaded into a temporary directory, i want the installer to "register" them as "to-install" files, so they go to the propper directory, and at uninstall time they are well deleted...
Any help welcome, i'm really stuck

Thank you very much
