You could try running Windows in safe mode and seeing if that allows the product activation without the error.

Thanks for the suggestion, Bob. It should be easy to switch between the modes, but I understand it can be frustrating if you do not know where to find it.

For the benefit of other users, there is a drop-down at the top-right of Flowcode's screen that switches between light and dark modes.

From memory, I believe Chrome is isolated from a lot of locations on an Android phone for security (it is kind-of sand-boxed). That means it cannot read or write to local files. Perhaps this accounts for the problems you are seeing.

Sorry you're having a problem. I'm not sure if I've seen this error before. Is there anything 'unusual' about your PC or Windows?

It seems like the Flowcode activation app is not finding the downloaded licence file. Perhaps anti-malware software is preventing access to downloads?

Thanks very much, WingNut. Such a nice message. The world does seem a crazy place at the moment. I'd like to echo what you have said about Iain and Martin - we would not have this forum without their selfless support.

I downloaded V11 a few weeks ago, but V11 is giving me troubles installing last I tried to install it.

Thanks for letting us know. Can you explain what the issue is and we will try to resolve it.

Martin makes a good point and I would second using local variables where possible.

Also, I have added a rudimentary copy/paste for variables which should be available in the next core update of Flowcode v11.

I've just tried compiling an ATMEGA328 with PWM and it compiles without error for me. Make sure you are up-to-date with library updates. Also, it was tricky to see what the error is from a screenshot. In future, it is much easier to solve problems if the output is available in text (e.g. by attachin...
