I installed some Windows Builder stuff (not sure if related) and I receive a few errors when the IDE is starting up now. I was trying to follow a tutorial on how to use WindowsBuilder to make a simple UI and was getting some errors but thought I should start with the ones below. Any help would be appreciated. Thx!


1:An internal error occurred during: "Check license status".
ECLIPSE_HOME is undefined.
2:An internal error occurred during: "Init CodeMix".
ECLIPSE_HOME is undefined.
3:An internal error occurred during: "Initializing CodeMix Engine".
Cannot read the array length because the return value of "" is null

These messages refer to "CodeMix", which isn't from You'll want to contact support from whomever provides it.
