When will IronPython version used for Finalbuilder be updated to IronPython 2.6?&nbsp; Merely replacing the DLLs used will not work, as the VSDLRHost.dll expects a specified asembly.&nbsp; When I set Tools/Options: Script Option = IronPython 2.6, I would expect FinalBuilder to use that version.&nbsp; However, a query using sys.version results in 2.5.0 being returned, not 2.6.0 as expected.&nbsp; Interesting sys.path returns the correct path.

Executed from FinalBuilder ScriptEditor  
sys.path=['C:\\Program Files\\IronPython 2.6\\Lib']  
version=2.5.0 ()  
&nbsp;

I verified the same commands using IronPython Console return expected results

\>\>\> import sys  
\>\>\> sys.path  
['C:\\Program Files\\IronPython 2.6\\Lib', 'C:\\Program Files\\IronPython 2.6\\DLLs', 'C:\\Program Files\\IronPython 2.6', 'C:\\Program Files\\IronPython 2.6\\lib\\site-packages']  
\>\>\> sys.version  
'2.6.0 (IronPython 2.6 (2.6.10920.0) on .NET 2.0.50727.3603)'  
\>\>\>

Hi Lee,   
  
 We’re waiting until the final version of 2.6 is available before we update FinalBuilder. It shouldn’t be too far away.
