There used to be multiple editions of WinGDB in the past. We observed that it was somewhat confusing and currently there is only one commercial edition, named WinGDB Unified. It basically allows you to develop for any supported platform.

In case of development for Android mobile devices, you also have additional choice of free Android-only edition. Please look here for the downloadable package and more info. You can use commercial edition for Android development also, although Android target is still without "official" support.

For WinGDB 3.x, there are only two kinds of upgrades, depending on which version you were using before:

• Upgrade from 1.x (any edition) to 3.x
• Upgrade from 2.x (any edition) to 3.x

Currently we offer only node-locked licenses. That means a single license for WinGDB is tied to a single computer. The license can be moved to other computer (e.g. in case of hardware change), but you may use a license of WinGDB on one computer at a time.

Another software licensing option is the so-called floating license (network based). It involves installation of special server software on some computer in customer's network. The server controls the number of simultaneously active copies. Usually the price of such license is much bigger than the node-locked variant. We do not provide this option at the moment, as we want to keep the price low.

No, you have to buy two licenses. But note that we offer a large quantity discount even for two licenses.

We sell WinGDB through two US-based distributors, BMT Micro, Inc. and FastSpring. They complement fairly each other in terms of available payment methods. Also they are continously expanding their capabilities. Please review available methods on respective order pages and choose the one which suits you the best.

Purchase orders are typically used by corporations. If you're an individual person, some other form probably would be more convenient for you. A purchase order is completed in the following steps:

• Please choose edition (or upgrade) you want on the Purchase page, and select the FastSpring distributor.
• On the Order page, select "Purchase order" payment option. You will be asked for a PO number which should be the number that your company uses to track these orders, it will appear later on the invoice. Also please enter your contact information and quantity of ordered licenses.
• After completing the order, you will be informed that the order is waiting for approval. Please allow one business day for that.
• When the order gets approved, you will receive further instructions and a link to the invoice.
• FastSpring accepts several payment options for purchase orders (credit card, money order or check). Please choose one which suits you the best.
• After the payment is received by the reseller, the license keys will be sent to you via e-mail. Please note it is the reseller physically sending them. Also it might take few days for the payment to be delivered, depending on chosen payment method.
• Keys also might be delivered before the payment (made within 30-day term). In such case, please contact us at support@wingdb.com before placing the order.
• At any moment you can contact us at support@wingdb.com and we will provide an information on the order status.

Please contact respective distributor (FastSpring or BMT). In case if you need just a quote (sometimes called a "pro-forma invoice"), enter appropriate data on the orders page, and when the final price is calculated, just print out the resulting page from your browser.

You can order multiple licenses at once. You will receive as many license keys as the number of licenses you ordered. Each key must be registered to bind it to particular computer. You can choose one of two ways to do that:

• Manually distribute the keys among persons using these computers, one key per user. Then, each user will select the Register option from the WinGDB menu and enter the single key. WinGDB will generate a mail that should be sent to license_request@wingdb.com. Appropriate license file will be sent back within 48 hours (typically several minutes).
• Provide the whole list of keys to each user. The Register option accepts multiple keys at once. The first free key will be assigned to particular computer during the registration.

You can read more about product registration here.

That means the key is for different edition that you have currently installed. It should not happen if you bought Unified Edition key, however it is possible for non-Enterprise old keys. Edition is being chosen during installation (for WinGDB 2.x or newer) or in the Registration Dialog (for WinGDB 1.x). Possible solutions:

• Reinstall WinGDB and choose an edition which matches the key.
• Use a different key, suitable for installed edition.
• Use an upgrade key (enter both the base and the upgrade key in the dialog).

Registration mails are processed by an automated service operating 24/7 under license_request@wingdb.com mail address. Sometimes technical problems may appear, for example:

• E-mail is not a robust service. Sometimes it gets delivered with delay or goes missing.
• Message could be blocked by some antispam software.
• Network outages.
• Some mail clients (notably webmail, like Horde, etc.) might alter messages accidentally corrupting them, or use atypical MIME headers causing the server to fail. This is extremely rare, but still possible. Apart from webmail clients, we also experienced such problems with Lotus Notes e-mail client. Also "Open mail client" button sometimes does not work properly with several clients. Manually copying and pasting license mail to your mail client should help in such case.

In case you do not receive any response in 24 hours, please do the following:

• Make sure that you're checking the same mail account as you sent the registration info from.
• Check your spam folders.
• Resend the information once. If you used a webmail client before, you might try traditional mail client this time if possible.
• If still no success within 1 hour, write immediately to support@wingdb.com (which is human-served). Please do not repeat sending the request to the automated service without contacting the support, as chances are that you will only trigger same behaviour repeatedly (still getting no response).

Currently we offer only quantity-based discounts. It is good for resellers which can buy a quantity in advance and are active in attracting potential customers. Please look here for our pricing table.
