System environment variables

To resolve issues and bugs, the GEM-CAR development team may require some data from your computers. This data is necessary to run proper investigations and diagnostic tools and figure out what is going wrong with some features. If you run into bugs while using GEM-CAR 14 or 2022 and you contact technical support agents, they might ask you to create system environment variables in Windows 10 or 11. These variables will allow GEM-CAR 14 and 2022 to collect and send the required data to the development team.

GEM-CAR Environment variables

V2VLogging

This environment variable allows GEM-CAR 14 and 2022 to collect and send data to the development team concerning the local features. This data could be related to any offline feature on one or several computers on the local network. Define this value to Full to enable the variable or None disables it.

V2VHttpLogging

This environment variable allows GEM-CAR 14 and 2022 to collect and send data to the development team concerning the online features of the software. This data could be related to integrations with suppliers’ websites or any other feature that involves data exchange between GEM-CAR 14 or 2022 and its partners. Define this value to Full to enable the variable or to None to disable it.

DOTNET_ENVIRONMENT

This variable assigns GEM-CAR 14 or 2022 to a development environment. The value of this variable can be either defined to Production or any other value provided by the support team. If it's not defined, it's equivalent to Production.

Create, delete or modify environment variables

If we ask you to add environment variables, first check if they are already on the list. If so, see Modify environment variables. If they are not on the list, see Create new variables. You may need to create environment variables on a single or on several computers on the local network. They can't be deleted or disabled remotely by the GEM-CAR development team. Consequently, if they're no longer required, you can disable or delete them. Some variables can't be disabled or deleted.

Environment Variables window

Follow the steps below to go to the Environment Variables window. From this window, you can create, delete or disable environment variables. The procedure is the same for Windows 10 and 11, but the interface is different.

  1. Enter Variable in the Search box of the Windows taskbar and open Edit the system environment variables.
  2. From the System Properties window, on the Advanced tab, select Environment Variables.

Windows 10

Windows 11

  1. Under the System variables list, select New.
  2. In the New System Variable window, enter the name and the value and select OK.
  3. Back to the Environment Variables window, select OK. *

Modify environment variables

To modify environment variables, follow the steps below. The procedure is the same for Windows 10 and 11.

  1. Under System variables, select the variable on the list then select Edit.
  2. In the Edit System Variable window, modify the name and the value and select OK.
  3. Back to the Environment Variables window, select OK.
