Go to Menu, Project, then Compile to compile and create the setup file. This will create a complete installer. Run the Setup and your application will be installed correctly. Innosetup offers an awesome alternative to create great looking Installers for free.
/SUPPRESSMSGBOXESInstructs Setup to suppress message boxes. Only has an effect when combined with '/SILENT' or '/VERYSILENT'. The default response in situations where there's a choice is: Yes in a 'Keep newer file? ' situation.
It defines two languages: English, based on the standard Default. isl file, and Dutch, based on a third-party translation. The internal name of the language, which you can set to anything you like.
Inno Setup is a free installer for Windows programs by Jordan Russell and Martijn Laan.
For the best compression use:
[Setup]
SolidCompression=yes
Compression=lzma2/ultra64
LZMAUseSeparateProcess=yes
LZMADictionarySize=1048576
LZMANumFastBytes=273
SolidCompression, it helps, if you order files in the [Files] section by an extension and similarity. Though the solid compression is not recommended for huge installs.LZMANumBlockThreads to speed up the compression.With this settings, you will need up to 11 GB of memory on the machine that runs the compiler; and up to 1 GB of memory on the system that runs the installer.
For details, refer to the Compression directive documentation.
Though I'm not sure, if you can match FreeArc even with this settings.
If you want to use FreeArc compression, use unarc.dll.
Note that ISTools does not allow the lzma2, as that was introduced in the Inno Setup 5.3.9. Always use the latest version of Inno Setup.
