Invalid Charfx License 3100000 in Web Forms Posted April 27, 2009 · Report reply Hi We have purchased CharFx7 license for Webforms. We have installed the development license in our dev machines and the charfx is working fine. We build a release package and installed the same in testing server, then we got the error "Invalid ChartFxLicense3100000" while trying to view the chart. Again i tried to install the production version of the license in the testing server and i tried to view the chart, in this case we Invalid "ChartFxLicense3100000" didn't occur, but we are not able to see any chartimage or toolbar. We are using IE7 for the application. The chart area has got only a red cross at the top and nothing is getting displayed. Please let us know how to solve this issue.
