SOLVED: Upload question - slightly advanced

Hi there, Ive just rebuilt my dev system, new instalaltion of IDE 1.8.10
Compiles OK - very well worn sketch, no problems there...

BUT - when it hits the upload phase - it fails immediately...

Bootloader file specified but missing: C:\Program

Sketch uses 79866 bytes (61%) of program storage space. Maximum is 130048 bytes.

Global variables use 13200 bytes of dynamic memory. Cannot run program "REMOVE/bin/avrdude": CreateProcess error=2, The system cannot find the file specified

An error occurred while uploading the sketch

What happened, Where did "REMOVE/bin/avrdude" go ?
Is this going to be a simple reinstall the GUI ? or something more.


The "REMOVE" is a placeholder which is meant to be replaced when the actual path to avrdude is discovered by the IDE. When it is not replaced, this indicates that avrdude is missing. This can happen if a Boards Manager installation fails to install the tools. You can follow the procedure described in this help center article to fix it:

Ok, thanks...
That makes sense, I do use custom boards & platforms, and ‘thought’ I’d rebuilt them properly.

I did another new reinstall - using the current 1.8.13, and re-tweaked my txt files...
It all came back to life
Thanks for the pointer!
