Folder Structure

The setup program copies the development tools into sub-folders of the base folder. The default base folder is: C:\KEIL. The following table lists the structure of a complete installation that includes the entire line of the µVision3 development tools. Your installation may vary depending on the products or add-ons that you have installed.

In this users guide, we refer to the default folder structure. If you install your software in a different folder, you must adjust the pathnames to match your installation.
