Error after installing my program

naem name

Hi all,

I have developed a winform application using c#. I used visual studio 2015.

I managed to create a setup.exe for my project so that any user can install the project on his or her machine.

After obtaining setup.exe for my project, I managed to install the project on my pc. The setup then creates a shortcut on the desktop.

After double-clicking the shortcut, the application start, it loads the first 2 forms of the application the it produces an error.

I have attached a screenshot of the error generated.

The error was generated after a successful installation. It was generated when the appliation was running after it has been successfully installed.

Note: If i go to build then start application using visual studio 2015, the application runs without interruptions or errors.

Please help. Thanks in advance.

this error seems to be your database connection string you have provide is different, may be the path is not found.
which database are you using, if you are using sqlserver then take offline as .mdf file and put it into local drive then connect to that, and make exe

Hi Naem,

Could you please share the code you are using for connecting with db.This issue is related with the path you have specified for db in code.Either your db is not created in the installation folder or you donot have permission to create a db in the folder.

Error seems that your Sqlite db was not opened by your application, make sure that the directory of the database has proper read/write access, try running your application as an administrator.

Also make sure that db exists on that path.

Checking this stuffs will fix that issue

hey there !

I hope that you had not use local db (mdf file). Instead of that try with SQL server.
