WuInstall PRO Licensing
How is the WuInstall license price calculated?
You can calculate the price of your WuInstall license using the license calculator. The price depends on the number of machines, which you want to patch within your organization using WuInstall.
This is the current price model:
The prices above are yearly subscription fees. The license is always valid for one year from the date the subscription fee was paid.
For educational organizations (schools, universities, ...) the price of WuInstall PRO Basic applies, regardless of the number of servers or workstations.
How do I get updates of WuInstall PRO?
You can get the latest WuInstall 1.x version by dropping an email to firstname.lastname@example.org. All WuInstall 2.0 customers have access to a customer portal, where they can download the latest version of WuInstall 2.0 at any time.
How long is the WuInstall license valid?
The WuInstall license is valid for the licensed number of machines for one year from the date the subscription fee was paid.
How does licensing work if I am a IT service company and want to provide WuInstall to my customers?
If you are doing the patching as a service to your customers and WuInstall is also not used any more if they are not serviced by you any more, it is fine if you buy the WuInstall subscription for your company and use it on the machines of your customers, just count the number of machines of all your customers.
If the customers are doing the patching themselves and you are just providing them with the software (reselling it to them), then each customer needs a separate license, but you can contact us for a reseller discount!
How to calculate licenses if I only use WuInstall once per machine (e.g. for initial setup)?
If you a computer repair company or deliver pre-installed clients to your customers and are using WuInstall on every delivered machine just once, just take the average number of patched machines per month (or patched machines per year divided by 12) to calculate the number of machines to be licensed for your subscription.
