USING C51 V7.50 WITH A C51 V8 PSN
Applies to: C51 C Compiler
Information in this article applies to:
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?
To downgrade C51 Version 8 to C51 Version 7.5...
Install Version 8 from the CD-ROM and add your license as
explained in the
Licensing User's Guide.
Download the file attached to this article using your License
ID Code (LIC).
Unzip and run the file inside the archive. Select exactly the
same folder that you specified for the PK51 or CA51
Open TOOLS.INI (located in your installation folder)
with a text editor.
Within the [C51] section, look for the line
Copy that line and change LIC0 to SN in the
copied line so that it reads:
- Save and close TOOLS.INI
Version 8 is now downgraded to Version 7.5.
This method only works for Single User Licenses. It does not
work when you are using other license types, i.e. Floating User
