  Howdy,
  
  I have some need’s to open the app on windows 2008 r2 or windows 7, and the flexviewer that i have setup to display pdf files.
  
  On these environments, i have the error bellow.
  
  Is it the lack of some support/framework/whatever that i need to install, or this OS’s are really not supported anymore?

  thanks in advanced,

  Hi Jorge,

  The minimal system requirements for using the FlexViewer is given in the link below:
  
  https://www.grapecity.com/componentone/docs/win/online-flexreport/overview.html

  Please make sure you are using the appropriate OS version.
  
  If you still get the issue at your end, share the report with dummy data that is causing an error so that we can replicate the same issue at our end and assist you accordingly.
