# IDE Startup Error: OpenSSL Libraries Not Found

The IDE cannot display itself in this browser because it could not find and/or load compatible OpenSSL libraries. OpenSSL is required for communication between the IDE and the browser.

This error should never happen, because the IDE has a private version of OpenSSL in the `idebin` subdirectory of the Allegro CL installation. Please reinstall Allegro CL to see if the directory reappears. If the `idebin` directory is still missing, please contact support@franz.com and give the following details:

- Operating system and version
- Browser and version
- ACL version
- Name and version of any antivirus software installed

See our installation guide for more information.
