At Licensepromo, we understand that you may be hesitant to use our service; After all, how is it possible that we can offer you the latest Office and Windows packages at such low prices? This must be some kind of scam, right ? No. We can offer you these prices thanks to a sophisticated purchasing strategy of our buyers who operate worldwide. 

We buy large volumes of licenses on all Microsoft (and some other) products worldwide (China, America, Eastern Bloc and Europe) from companies that have overstock or unused licenses in order to get the lowest possible price. We also buy the licenses from failing companies that are no longer used. We also have minimal overhead, such as no operating costs for a store and do everything digitally.

By moving large quantities both in purchases and sales, we can also keep our margins very low to the benefit of the consumer.

Dealers who have a contract with Microsoft are obliged to charge set prices. We do not do this and do not have a contract with Microsoft. Therefore, we can also stay below the set prices.

All licenses are 100% legal and you can read why in the next section. We have been in business for more than 4 years and provide high quality license keys with warranty. Our keys are NEVER resold more than once and every customer gets an activation confirmation from Microsoft on his key so you can also count on the official support channels of Microsoft and all corresponding updates. Contrary to what many think, these are not "volume licenses" or "developer licenses" or even "OEM" but full-fledged Retail licenses.

Of course ! The sold licenses are completely legal and working. We encourage all our customers to register their email address and register their specific Microsoft Office product key via Microsoft online activation to ensure authentication and tracking of their authentic software products.

Most of our licenses are new but also pre-owned (It is a key / license that has previously activated a software package. For example on a laptop. When replacing this software or when replacing the laptop, the installed software will no longer be used. The license can therefore be applied again). We always guarantee the functioning of the activation of our keys!

Definitely. There is even a European ruling confirming the sale of second hand software licenses.

European decision of 24 April 2012

Second-hand software licenses are completely legal, European Court ruled

The European Union Court of Justice has recently taken a milestone decision in favor of the commercialization of second hand software licenses of any kind. According to this, once a software seller or distributor sells a copy of any software tool, it automatically loses its exclusive rights to distribution, making it completely legal for companies and individuals to re-sell their own copies, legitimating this niche market for companies such as the German based UsedSoft, the company that took the case to the European Court. In addition, it is clearly stated in the Court decision that no difference could be applied between physical media and download products. "It makes no difference whether the copy of the computer program was made available by means of a download from the right holder's website or by means of a material medium such as a CD-ROM or DVD," the court ruled. "Even if the right holder formally separates the customer's right to use the copy of the program supplied from the operation of transferring the copy of the program to the customer on a material medium, the operation of downloading from that medium a copy of the computer program and that of concluding a license agreement remain inseparable from the point of view of the acquirer. The transfer of property of the licenses also implies the transfer of the legal obligations stablished for both parts, including maintenance and upgrades, also meaning that multiple user licenses for instance cannot be split and sold separately, since the original conditions would still apply in case of a re-sell. However, this decision only affects the European markets, since previous Court decisions in the United States followed a completely different direction. In the precedent-setting case Vernor vs. Autodesk, it was established that US buyers purchase the ability to use a license, but they do not own the software, making redistribution not legally possible. This does not prevent American users to purchase licenses outside the USA, although the legality of such possibility is still unclear. Nevertheless, this European Court decision has a huge importance for companies, since it eliminates the distinction between the purchase of a license and the purchase of a product. The implications of this measure for international trade and intellectual property legislation on the long term still would need to be further discussed, but on the short term the cost-saving potential for European organizations is undoubtedly very important. We will see in the future the real impact that the opening of this market has for European Union based companies.

Smartscreen cannot read this image, but says quite correctly that this image may contain executable files (in this case, the Office installation file). That is why the message "CAN be harmful" and not "IS harmful".

Upgrading from Windows 10 or 11 Home to Windows 10 or 11 Pro is not so obvious.

If you enter the purchased licence key in a Windows 10 or 11 Home, you will receive an error message because Microsoft does not allow this.

However, there is an easy solution.

In Windows 10, go to settings - update and security - activation....
In Windows 11, go to settings - system - activation - upgrade

There you choose for "change product code".

Then enter one of these keys:






If your 4 keys did not work. Then try repeating the procedure, but without an Internet connection.

This key will start your upgrade to Windows 10/11 Pro. However, after this, your Windows Pro is not yet activated as these are generic public keys. Then repeat the steps above but with your purchased key. Your Windows Pro will then be activated.

Most problems with the installation or activation of Office are caused by the fact that there is still an old or different Office version on your system. On a new laptop, for example, there is another trial version of Office 365 that conflicts with new versions.

Examples of errors :

  • For example, you will receive error code 30182-1 (2).
  • Office only wants to install 32-bit and gives you a notification
  • Your office question behind an email address for activation
  • You do not get Office activated or the key turns out to be incorrect.

All these errors can be solved by deleting old or other Office versions.

You can read how to do that here:

or for Mac :

If you want to check if you are working with the correct Office version, go to File - Account and in the right column you will see your version of Office and the activation.

For Windows :

After entering your license key and activation, your Windows is automatically linked to your computer's Mac address. Microsoft creates a profile of your device. On the basis of this data, a new installation checks whether your device was already equipped (with an activated version) with Windows 10. You can then reinstall it as much as you want on the same computer. You cannot use the license key on another PC.

For Office :

This depends on the license type. Check the product description to see if the product is suitable for account installation or valid for 1 PC or installation only.

You create an Office account at and enter your license key. After this, your product will always be present in your Microsoft Account. You can check this by going to and clicking on 'services and subscriptions' at the top of the menu, then you will find your product and you can install it again. Attention, only 1 installation is possible, so you first have to uninstall your installation on the other computer.

Attention : your original license key will no longer work if it is linked to your Microsoft Account and Microsoft will not allow a second use. You must therefore use your account for the reinstallation.

Attention, if you did not create a Microsoft Account or you bought a license without an account, you also cannot use your license key again to reinstall or activate !
