Thank you for your question and for reaching out with your question today.
Here are some steps and considerations to help you address this problem:
- Make sure that the driver you're trying to install is compatible with the specific version of Windows running on Amazon AppStream 2.0. Drivers designed for other Windows versions may not work correctly.
- If you have successfully installed the driver on one instance but encounter issues on another, ensure that the driver installation process is consistent across all instances. Pay attention to file paths, permissions, and any specific settings required by the driver.
- Driver signing is a security feature in Windows, and disabling it (as you attempted with
TESTSIGNING ON) can introduce security risks. Instead of disabling driver signature enforcement globally, consider digitally signing the driver yourself using a trusted certificate. This is a more secure approach.
- Acquire or generate a code-signing certificate from a trusted Certificate Authority (CA). Use the certificate to sign the driver files. This requires access to tools like SignTool from the Windows Driver Kit (WDK). Signing the driver with a trusted certificate should allow it to be installed without needing to disable driver signature enforcement.
- Ensure that Amazon AppStream 2.0 instances are configured properly and have the necessary permissions to install drivers. Amazon Web Services provides documentation on configuring AppStream instances.
- AWS support may be able to assist you further.
