Best way to making offline installer out of web downloader

[chessgod101]

Depending on how complex the installer is, you could use a software such as SysTracer to take snapshots on the computer before and after the installation and compare what has been changed. You can then use the difference log to help you create your own installer with Inno. However, this would fail if the installer generates system specific files or registry entries. I know it is a lot of work, but typically when a company has only an online installer, they usually have a reason why they do not want you to install in offline. I think it allows them to monitor both where and how many times the application has been installed.
