### Upgrading package

              Gadget permissions

              

A bug from BIOVIA creates issues with group names including spaces. The group *Discngine/LiveDesign Connector/Administrators* was kept for backward compatibility reasons but it is highly recommended to use only the group *Discngine/LiveDesignConnector/Administrators* introduced in version 3.4.46 and to move associated users and subgroups into this new group.

1. On the Pipeline Pilot server, open the command line prompt as an administrator from the windows start menu (Right click > execute as administrator) and change the directory to `[scitegic_root]\bin` (or `[scitegic_root]/linux_bin` if you are on a Linux server).
2. Uninstall the Discngine LiveDesign collection executing the following command:

`.\pkgutil.exe -u discngine/ldconn`
3. Remove or backup the folder `<scitegic_root>\PPS\apps\discngine\ldconn`.
4. Place the folder `ldconn` from the package in `<scitegic_root>\PPS\apps\discngine\`.
5. Install the Discngine LiveDesign collection executing the following command:

`.\pkgutil.exe -i discngine/ldconn`
6. Ensure that the gadget is correctly deployed depending on your installation (See [the LiveDesign installation section](/public/docs/connector-ld-pp-admin-guides-installation#livedesign))
7. Ensure that the security configuration for Pipeline Pilot server is correctly setup (See [the Pipeline Pilot server configuration section](/public/docs/connector-ld-pp-admin-guides-installation#server-configuration))
8. Restart the Apache server:
  - Open the Pipeline Pilot server administration page
  - Navigate to *Maintenance > Manage Server* in the left pane
  - Press the "Restart Apache" button
