Hey I'm new here, first time posting but I started using this software for college wanted to try using it at home but whenever I try to compile to target I'm met with an error message saying I need to install the AVR compiler toolchain. I installed it and it said if I had flowcode open then to restart it and I did that however I'm still met with the same error message? I've even deleted the software and reinstalled it and I'm still hit with the same error message I tried to find support with the company but I have no idea. Oh also I'm trying to do this for an UNO R3 arduino, I can't find what model (software says there's a bunch of stuff with anacronyms but I'm not sure which one came with the kit I bought just says it's an UNO R3. Is there a way to fix this?

You need to go to Build->Customise->Locations and set the path for the AVR compiler (C:\Program Files (x86)\Flowcode\Common\Compilers\avrv5\).

I'd try Uno R3 PDIP (the SMD/PDIP - just refer to how the MCU is mounted, I don't think it should make much difference?) - in the first instance...

Make sure to set the COM port in the project configuration too (bottom right) - some clones might need a driver installing - but most should work with Windows as is.
