By default SQL Server Express installs and uses .\SQLExpress which is a named instance and in order to install default instance you need to specify ‘.’ during the installation. If the user did not manually change the setting to install default instance, the setup will install instance name as SQLEXPRESS.
When running setup.exe from the command prompt, specify DisableNetworkProtocols = 0, in order to install the required network protocols such as TCP/IP & Named-pipes. The Network Service account is used as a service account for SQL Express, by default this account does not have any permissions for instance to attach a database from a directory. In order to perform any admin activities either the user can use a user instance by adding User Instance=True to the connection string. As this is a special type of instance tha SQL Express supports that runs a separate SQL process in the user context that has permissions on the requriedprofile directories.
In SQL Server Express with Advanced Services instances the user might get error “The file ‘devenv.exe’ is missed” when the Business Intelligence Development Studio (BIDS) is opened. The workaround for this problem is
Redirect the BI Development Studio shortcut to the location where devenv.exe actually exists.
- From the Start menu, choose Search.
- Search for “devenv.exe”
- Record the location where you find it.
- On the Start menu, right-click the shortcut from BIDS.
- Enter the correct path to devenv.exe in the Target text box.
- Click OK, to update the shortcut.
