Finalbuilder crashes

Hi

I am testing FinalBuilder (version 6.3.0.1816) and try to do some filemanipulation (compile some sources).

One of the step in this is a Path manipulation where I exchange the extension of the filenames.

I goes ok for the first 1083 files but then Final Buider crashes with this error :

Path Manipulation: File extension changed
Error Executing script : OnExecute
FB60ActionCtx.CustomActionExecuteContext
Access violation at address 00BC435C in module 'oleaut32.dll'. Read of address 0D1C1000
Line: 129
Char : 1

 

What can I do for solve this ???

 

I am working on Windows 2003 64 bit Standard Edition.
