EPiServer License violation!

March 27, 2008 | 3 comments

Have you been annoyed by the exception “License violation! License is already in use at another online site” when you switch from one web site to another on you developer machine?

I have and the reason is of course that I use my developer license file in more than one place.

To workaround this problem you can always restart EPiServer Scheduler Service and recycle your application with an iisreset.

EPiServer appears to use the Scheduler Service for more things than just executing scheduled tasks. It is used when a central communication point is required like when you need to synchronize licenses between web applications…

    Hi, another way around this problem (if you use windows xp) is to you this application a colleague wrote.
    It’s called ultimate web switcher, and it you only need to have one instance in IIS (Default Web Site). Then you add the sites you are developing to this application and you can eaaily switch project by just two clicks.

    Check it out here: http://uws.kompressor.se/

    It’s a ClickOnce application, so you need to use IE to install it..

    Hi, I am getting the “License Violation” error on a test server that is hosting more than one EPiServer site. I am using Host Headers to distinguish between the sites. All sites need to be online at the same time. Is there a way round this? Is it possible to order a license for a web address (in stead of an IP-address)?

      You either need a unique license per web application or an Enterprise license that allows multiple sites and can be used in more that one web application.
