Problem installing demo database
Saurav did get before me in writing this blog post. Have you ever seen below error when installing the demo database.
Could not connect to the SQL database. (-2147467259 master ). This can be caused by insufficient permissions. Indirect permissions through Windows group memberships may not work as expected when User Account Control (UAC) is turned on.
Few resolutions to the problem
1) UAC is turned on.
2) SQL server is not running
3) Your user doesn’t have sufficient privileges on the SQL server.
4) Old database file are left on the system.
Take a look at Saurav’s blog for the solutions. Saurav’s blog post is found here
