Switching from Evaluation Editions to Commercial Editions

To upgrade the evaluation edition of a compiler to the commercial edition, enter the license key printed on a purchased compiler package to CS+ IDE (while installing or after having installed the IDE). This lifts the restrictions on functionality of the compiler for the target MCUs, upgrading the compiler to the commercial edition. For details, see the following manuals.

Upgrading Versions of Compilers

The compiler licenses differ per version. For example, V1.**.** and V2.**.** have different licenses since they have different version numbers.

Upgrading of versions of compilers is for a fee and requires a separate license key. If you do not have the license key for a new version, upgrading makes your compiler the free evaluation edition of the new version, even if you have the license key for an old version. You can still use the old version as the commercial edition in such cases.

Updating a Compiler

Update your compiler with every revision so that you are using the latest one. Refer to Tool News for details of how to update compilers.

Information on updating (Tool News) >>

Updating from revision to revision of the same version is free, while updating from version to version incurs a charge, as shown in the examples below.

  • Revision update: Free of charge; e.g. V2.01.00 to V2.02.00
  • Version update: Updating incurs a charge; e.g. V1.07.01 to V2.00.00 (commercial edition)
