Sorry, although we are constantly working on improving the VisualGDB’s capabilities and compatibility with various tools, we are not able to guarantee that every 3rd-party project created with an arbitrary version of the 3rd-party tool will always get 100% imported completely out-of-the-box. VisualGDB does its best at importing the common settings, such as preprocessor macros and include directories, however if you have overridden advanced Keil-specific options, you would need to adjust the imported project manually in order to reflect that. We have indeed published a detailed tutorial explaining this process step-by-step.
