An error occurred during the activation of a particular registration

Question

I have created odata service and pack up into the Web installer. That package is working properly once I installed on my computer but I can't use it on other computers when I tried to run on different computers, it comes up with the following errors:

Any help would be really appreciated.

Answer 1

The exception tells you what is wrong:

The ConnectionString property has not been initialized.

When you're creating your connection you have to define the ConnectionString beforehand.
