This error can appear when a certain database file in the Data folder directory of the application is not read properly. This can be because of the location of the Database file changing, the installation path was changed, or the current user does not have permissions to read the Data folder directory.
The easiest method to get this resolved is to open the CardExchange Config tool and reaffirm the database file in your Data folder.
Navigate to C:\Program Files (x86)\CardExchange Solutions\CardExchange Gateway
Find these two files:
CardExchange.Config.exe
CardExchange.Gateway.exe.config
You will need to drag the .config file on to Config.exe to open it. See image below
Click Yes to open
The configuration tool will now open with a couple columns for you to select. On the right side, select Connection Strings / Application.MySettings.Database
Set the provider to SQLite.
For the Database file row, we want to point this to the cegateway.sqlite file that is found in your Data folder. If the application was installed in the default locations, you can find the file in this path here:
C:\Users\Public\Documents\CardExchange\Data\
Select Browse next to the Database file row.
Select the cegateway.sqlite file and click Open.
You will return to the Configuration Tool window. Select Save in the top left corner, and close the configuration tool. It will ask you one more time if you would like to save, select Yes.
You should now be able to open the Producer and Visitor applications.
Still Having Issues?
If this error is still occurring, reinstalling the software will be the next thing to do. Uninstall the application, and rename or remove the currently existing Data folder.
When you reinstall the application, ensure that all installation paths are set to the default paths:
Program Files: “C:\Program Files (x86)\CardExchange Solutions\CardExchange Gateway”
Data Folder: “C:\Users\Public\Documents\CardExchange\Data\”
If problems are still occurring after reinstallation, there may be a larger issue at hand. In this case, send a ticket to our Support team - Support@cardexchangesolutions.com
