I recently installed PSoC Creator 2.1 in order to eliminate some compatibility errors with
a PSoC project, I found on the Web.
However, since downgrading (uninstalling ver. 3.0 SP and installing ver. 2.1) I am met
with the Keil license error.
I have tried the suggested solusions; generating a new key online and adding it manually,
but they don't seem to do the trick.
Regarding the latter procedure, does anyone know if simply adding the "LIC0=" line
and including the key (generated online) is the way to do it?
It doesn't work for me.

Help is much appreciated.

You might want to file a CASE on this -


To create a technical or issue case at Cypress -

“Design Support”

“Create a Support Case”


You have to be registered on Cypress web site first.

Can you let us know what is the reason for which you had to downgrade from PSOC Creator 3.0 to PSoC Creaotor 2.1 ?

Note that if you are using any pre-compiled libraries as dependency libraries then you might face issues. Because Creator 3.0 onwards Keil compiler version is Keil-951 and previous versions it was Keil-903.
