Hi Emiliano, Please try doing the following, it may help. I know of once instance where this worked.
In the html file generated, remove the codebase property as below: Change: OBJECT ID="LabVIEWControl" CLASSID="CLSID:A40B0AD4-B50E-4E58-8A1D-8544233807AA" WIDTH=588 HEIGHT=475 CODEBASE="ftp://ftp.ni.com/support/labview/runtime/windows/6.1/LVRunTimeEng.exe" To: OBJECT ID="LabVIEWControl" CLASSID="CLSID:A40B0AD4-B50E-4E58-8A1D-8544233807AA" WIDTH=588 HEIGHT=475 Please also make sure that you have Mozilla 0.9.x or later. I hope this helps. Sincerely, Feroz
