## Contact

There is no contact form. Send an e-mail to **sales@nexcmp.com** — it covers licensing, renewals, domains and technical questions. Your license page at [nexcmp.com/licenses](https://nexcmp.com/licenses) also links to the same address.

## Before you write

1. Search these docs (press `/`) and check [Installation errors](https://nexcmp.com/docs/troubleshooting/installation-errors/) and [Update errors](https://nexcmp.com/docs/troubleshooting/update-errors/).
2. Collect the facts below — they let support answer in one reply.
