Support

A question, a bug, an invoice?

Write to support@novair.app, in English or French. Mainframe File Viewer is published and maintained by one person.

Activate Pro

Gumroad e-mails your licence key right after the purchase. In VS Code, open the Command Palette and run Mainframe: Enter my Pro licence key, then paste the key. Activation needs one connection to api.gumroad.com (through your VS Code proxy settings); after that, Pro works offline.

No key in your inbox? Check your spam folder, then find your Gumroad receipt; otherwise write to us with the e-mail address used for the purchase.

Machines

One key for one person, on up to 5 machines. A machine is counted the first time the key is activated in a VS Code installation: a new computer, VS Code reinstalled with its data erased, or a non-persistent virtual desktop whose identifier changes. Entering the key again, trying again after a network error, removing and re-entering it on the same installation, or updating the extension uses nothing. New computer or VS Code reinstalled? Write to support@novair.app with your purchase e-mail and we reset the count.

Invoice

Need an invoice? Use the “Generate” link at the bottom of your Gumroad receipt: enter your name and business address, add what your accounts need under “Additional notes”, and download the PDF. An EU business that paid VAT can enter its VAT number there: Gumroad refunds the VAT and the invoice shows no VAT. Gumroad cannot change an invoice afterwards.

Refund

Within 14 days of the purchase: write to support@novair.app or go through Gumroad, which handles payment as merchant of record. If your network blocks api.gumroad.com and Pro cannot be activated, the same applies.

Report a bug

Say what you did, what you expected and what happened, with the version of the extension. If you can, attach the copybook and a few records that reproduce the problem, with any customer data removed first.
