So think about what reasons could possibly cause that:

• Does that file actually exist at all?
• If it does exist, is it in a location where your project is expecting to find it?

The "Browse Information" is what Keil uses internally to find definitions so that you can use the "Go To Definition" feature.

Unfortunately, the Browse Information is only created as part of a successful build - so you can't use the browsing features until after you have done a successful build!

Since your build is failing, you cannot use the browsing features until you fix it.
