A setup for each newer version of Lasernet is required for any new installation and when upgrading from an older version of Lasernet. ### Prerequisite/Technical It is best practice to refresh the Stylesheet after upgrading Lasernet FO Connector as this could help avoid potential issue(s). Please, also use the following Register selection classes, located in **Lasernet** > **Setup** > **Backup parameters** > **Setup Default Selections,** in case an error like the following is thrown when using **Export**, **Import** or **Copy across companies**. The newly introduced upgrade framework in Lasernet FO Connector 6.18 should manage but could fail when using a TFS/Dev build as this would require executing [Microsoft.Dynamics.AX](http://Microsoft.Dynamics.AX).Deployment.Setup.exe. ![](https://cdn.document360.io/c831ef63-c6b3-48ee-b443-3e33644e4e2e/Images/Documentation/image-L2RMOF0S.png) ![](https://cdn.document360.io/c831ef63-c6b3-48ee-b443-3e33644e4e2e/Images/Documentation/image-CQOL18F2.png) ![](https://cdn.document360.io/c831ef63-c6b3-48ee-b443-3e33644e4e2e/Images/Documentation/image-J3K6DQGY.png) Error message: > [!CAUTION] > Error > > Please try to run ’Register selection-classes’ before processing. or > [!CAUTION] > Error > > Cannot create a record in Lasernet default export/import selection (LACDefaultSelection).
