QUESTION

I purchased a C51 compiler license and received C51 Version 8 and a Product Serial Number (PSN). The project I'm working on requires the C51 Version 7.5 compiler. How can I install C51 Version 7 instead of C51 Version 8?

ANSWER

To downgrade C51 Version 8 to C51 Version 7.5...

  1. Install Version 8 from the CD-ROM and add your license as explained in the Licensing User's Guide.
  2. Download the file attached to this article using your License ID Code (LIC).
  3. Unzip and run the file inside the archive. Select exactly the same folder that you specified for the PK51 or CA51 installation.
  4. Open TOOLS.INI (located in your installation folder) with a text editor.
  5. Within the [C51] section, look for the line LIC0=XXXXX-XXXXX-XXXXX-XXXXX-XXXXX-XXXXX.
  6. Copy that line and change LIC0 to SN in the copied line so that it reads: SN=XXXXX-XXXXX-XXXXX-XXXXX-XXXXX-XXXXX
  7. Save and close TOOLS.INI

Version 8 is now downgraded to Version 7.5.
