SQL Server failed to modify security permissions on registry key supersocketnetlib
It appears that the install did not create the new group that is necessary to access SQL server.
Solution: Create the Domain Local Security Group in Active Directory Users and Computers and the installation will complete successfully. To do this, you will need to add the group SQLServer2005SQLBrowserUser$SERVERNAME and make it a member of administrators.
Process: To add group, Click Start & Right click MyComputer. Left Click on Manage--> Local Users and Groups--> Groups.
Right click on Groups-->New Group.
Copy this text "SQLServer2005SQLBrowserUser$SERVERNAME" and then Paste in Group Name. Remember put your own server name in the place of SERVERNAME.
If you do not know what your server name is: - Click Start, - Point to All Programs, - Point to Accessories, - Left-click Command Prompt - Type in the keyword "Hostname" and your Server Name is displayed
Right click the newly created group & Click Add to Group.
Select users to add to this group. In this case, add administrator in the members area and click OK.
