It seems that the forum responses have deterred potential pirates from openly requesting software. I received this message in my inbox:
Would you be so kind as to pass on the download link or share the 101 MB installer for IAR's EW 3.20a? I have the 57 MB version but would really like to take a look at some of the source files included in the larger version to help me with my coding.
Well, Jim, I've just paid £400 for my SUA with IAR, and I'm not about to compromise the support I receive by 'sharing' the installer with you.
