The ARMbasic compiler runs on the PC, in combination with a BASIC support library that is installed on the ARM. This support library (firmware) will be updated from time to time to support new features. To upgrade that firmware you will need to purchase the upgrade.
This installer is meant for Windows either NT, XP or XPx64, Vista and Win 7 (both 32 and 64 bits).
The software is downloaded from the web, and run as an installer SETUP program.
Click Next to get started.

And its as easy as that.
