title: sql server 2008 express setup problem
body: <p>I previously had sql server 2005 express and uninstalled it.. I also uninstalled any vs related programs and installed visual web developer 2008 express edition with SP1. now that I am trying to install sql server 2008, I am seing error messages like no other and leave that alone without any suggestions..</p>
  
  <p>the latest one which I could not come to a proper solution on the internet is;</p>
  
  <p>consistency validation for sql server registry keys error which suggests
  "The SQL Server registry keys from a prior installation cannot be modified. To continue, see SQL Server Setup documentation about how to fix registry keys.</p>
  
  <p>as you might have guessed nothing so informative in the documentation... Also, when I try to delete any sql server related registry key, it does not let me. (yes I stopped all the related services..)</p>
  
  <p>anybody here that can be of any assistance?</p>
