2. Get the Inno Setup script plus related files by cloning the whole [monero-gui GitHub repository](https://github.com/monero-project/monero-gui); you will only need the files in the installer directory `installers\windows` however. Depending on development state, additionally you may have to checkout a specific branch, like `release-v0.14`.
3. The setup script is written to take the GUI wallet files from a subdirectory named `bin`; so create `installers\windows\bin`, get the zip file of the GUI wallet from [here](https://getmonero.org/downloads/), unpack it somewhere, and copy all the files and subdirectories in the single subdirectory there (currently named `monero-gui-0.14.1.2`) to this `bin` subdirectory
