Thank you for your post.
I don't have a clue why you are getting this message, and I know that doesn't help you.
My initial thought would be to open the database file in FileMaker Pro 10, and make sure everything seems fine. Then, close the file, and create a new Runtime, just in case something didn't work properly the first time.
Do you have access to another machine (Windows XP) with FileMaker Pro 10 Advanced? If so, try creating the Runtime on that machine and try launching the solution again.
Any additional information you can provide may be helpful in determining possible causes.
