License issues

[User (Legacy)]

We have a ChartFX for .Net (6.2) license, but use only the redistributable 

components within a web application, within a webservice, and within a 

WinForm application.  Each app is built on a common code base, including a 

class library that creates ChartFX.Chart objects.  The web app will save 

these objects as .jpgs that it will then stream onto a page.  A report 

webservice creates Chart objects that are then saved in PDFs.  And the 

WinForm app creates line Charts locally for display on the Winform 

(shocking, I know).

Here's my issue/question:  we had ill-advisedly and unnecessarily installed 

our license on multiple machines, and are in the progress of uninstalling 

those machines.  The problem is that on the webservers USED TO have ChartFX 

installed, everything works great.  But on the webservers that never had it 

installed, we get this error:

System.ComponentModel.LicenseException: Couldn't get Run Time license for 

'SoftwareFX.ChartFX.Chart'

Since SoftwareFX.ChartFX.Chart is a redistributable component, I don't 

understand why it's even using the LicenseManager.

Thoughts?  Clues?  Answers?

Thanks.

SoftwareFX.ChartFX.Chart is a re-distributable control as part of an 

application, it is not redistributable for all purposes (e.g. for 

development).

The way Windows Form licensing works is that the license for all controls is 

included inside the .EXE at compile time and then this .EXE and only this 

.EXE can use the control at run-time without the need for a license being 

installed in the computer in which it is running.

This applies only to building EXEs, if you build a dll, the EXE that uses it 

still needs to have a license of the control embedded inside.

The following KB articles should shed some light on this issue:

Q6101001. How to deploy a WinForms Application when it contains a wrapper 

object using Chart FX for .NET

I'm having the same issue but am confused as to how your reply in any way answers the poster's question.  We have a web server that has never had ChartFX installed.  We receive the error on the web site, not a windows app.

What part didn't you understand ? Did you take a look at the referenced articles?

You have a Web Server in which Chart FX has never been installed, then that server can not run Chart FX Web Forms. You need to install Chart FX in that server and you need a license for each server.
