Issue with database upgrade and plugin installation

I have successfully updated a clients nopcommerce database from 2.65 to 3.5. Her previous host did not supply her with the nopcommerce site files and only the database. I performed the database on top of a vanilla installation.

I am attempting to install the Tiffany theme for the client. However, when installing the plugins (all of which installed fine aside from the slider one) I get this error: here is already an object named 'Carousel3DSettings_SLider' in the database. Could not create constraint. See previous errors.

How do I remedy this situation? Do I have to manually edit a database entry and if so where/what database table would I find this information?

I like to know the why behind these things as it helps me to grow. Why would this error occur when all of the other plugins installed just fine?

Hi,

As we have already replied to your ticket, you do not need to re-install already installed plugin when you upgrade your nop.
I believe that you have modified your InstalledPlugins.txt file and the plugin name is not existing there - for this reason nop is trying to re-install it, but the plugin tables are already existing. So, just add this line to your InstalledPlugins.txt file and Restart the application:

SevenSpikes.Nop.Plugins.AnywhereSliders

I hope this helped you !

Beautiful!!!
That was the best advice and worked perfectly!
Thank you very much.
