This is for purchasing the PRO edition of the ImageCraft legacy compiler:
NOTE: a STD compiler license comes with PSoC Designer 5 SP5.4 or later and you do not need to purchase a separate license to use it. However, if you do require higher level of optimizations, you need to purchase PSoC1 5.4 PRO Compiler license.
