I have made an application in VS2012 that uses a database to store and retrieve data and I'd like to create a setup file for this application, currently I use InstallShield LE 2012.

I've tried to deploy the application with that, but when I install it in another computer it throws me an exception due to the database.

  • Can you be more specific about the exception being thrown? – Richard Vivian Dec 25 '12 at 07:16
  • "NullReferenceException: object not set to an instace of an object". And when I look for a contact in the deployed application in throws me something like the next: "Server not found", is something about the connection string with the database – AdrGuzman Dec 27 '12 at 03:55

If you are getting a Null reference exception error this is normally because some place in the code there is a failure to create an object. Then at a later point the use of this object fails with a Null Exception because the object does not exist.

In this case is sounds like there is a failure to create some object that is a dependency for creating the database. I know this does not really give much more insight into why this is happening. But here are some points to look for.

  • Is the target PC running an SQL server, or does your Install package deploy SQL Express?
  • Is it a MS SQL DB or Other
  • Does the user that you are running the install shield under have permissions on the SQL Server to create a database?
