Problem:

I get "Unexpected resource format" error when trying to compile my project. This doesn't happen for new projects.

Reason:

This error may be caused by repeated (double) post-processing of your project. There may be a call to ecc32 in post-build event of your project. Thus, EurekaLog is invoked twice: one for post-build event, second for IDE.

Solution:

Go to Project/Options/Build events and remove call to ecc32.exe from post-build event. If you want to have this command (for compilation outside of IDE) - then switch your project to manual control as explained here.

If this is not your case - please, contact our support. Send your .exe file for analyzing (it doesn't have to be runable).
