IBMs JRE does not like Githubs new SSL setup, so you can either try and fix it (the relevant part of the JRE is found in %RAD_HOME%\SDP\jdk\jre\lib\security)

or just get the latest ECD release from here:

https://github.com/ecd-plugin/ecd/releases

For version 3.0, download

https://github.com/ecd-plugin/ecd/releases/download/v3.0.0.201709092115/enhanced-class-decompiler-3.0.0.201709092115.zip

which contains a "features" and "plugins" folder. The contents of these need to go into the respective folders in your RAD installation, ie. %RAD_HOME%\SDP.

After starting RAD, it should be configured to use ECD for ".class" and ".class-without-source."
