This should get you going. Let me know if you run into anything I did not think of
Sorry....I in no way meant to keep you waiting. To short circuit any errors you are getting, I have posted the MDF files (the actual files that SQL Server creates) on the web for you to download. See the link below. You can just delete your existing StrataFrame and StrataFrameSample databases through SQL Server Management Studio and attach these. This side-steps the install and should get you going. Let me know if you have any questions.

No sir......... I done the things u said.. I deleted the 3 databases, but still no way... I hope that file help in something.. thanks.......
When you delete the database through the SQL Server management studio, check that folder to make sure the files are gone, and then you can retry the install.
