## Unable to use the {% data variables.product.prodname_copilot %} extension in the IDE
We recommend you follow the quickstart guide for {% data variables.product.prodname_copilot %} while setting up {% data variables.product.prodname_copilot %} on your machine. For more information, see "[AUTOTITLE](/copilot/quickstart)."
The {% data variables.product.prodname_copilot %} extension is frequently updated to fix bugs and add new features. It's important to keep your extension up to date because older clients cannot communicate with the {% data variables.product.prodname_copilot %} servers. Update your {% data variables.product.prodname_copilot %} extension on all the machines you have it installed.

## {% data variables.product.prodname_copilot %} not working in some files
If you're using {% data variables.product.prodname_copilot %} with a {% data variables.product.prodname_copilot_business_short %} or {% data variables.product.prodname_copilot_enterprise_short %} license, you may not see code completion suggestions in your editor for some files. This happens when a file is excluded from being used by {% data variables.product.prodname_copilot %}. Content exclusion can be configured by a repository administrator, or by an organization owner.
When a file is affected by a content exclusion setting, {% data variables.product.prodname_copilot %} will not suggest code completion in that file, and the content of that file will not be used to inform code completion suggestions in other files.
