Hello Rich,
Please, are you trying update KDS 3.0 and KSDK 1.2 on Windows or Linux? In header you mentioned Windows.
Do you have 64-bit installation package for Linux? KDS 2.0 and KSDK 1.1 does work on Fedora without problems?
Did you follow all instructions for installation RPM?
Please, what GTK files are missing? Please, can you make a screenshot of the error/warning message? Is it error or warning - after this message, is installation completed?
Are you able to flash any demo to your board?
Thank you for your feedback.
Best Regards,
Iva
