Sometimes re-installation of a Boyum add-on is needed and commonly requested by our support team. Here's a step by step guide on how to do that.
1. Close the B1 Client
2. Use the re-installation utility found in the b1up download package and remove the lines of the add-ons you want to re-install. Also, tick the box "Remove add-on files". Configurations are stored in the database so those will stay intact.
3. Make sure that all 3rd party software is disabled (antivirus, firewall, antimalware, etc.)
4. Start the B1 Client in "Run as an administrator" and start the install process again
