&nbsp;&nbsp;Hi.

I'm running FinalBuilder 7.0.0.515 and trying to build a pretty basic Delphi 5 project.

It was working ok, although it did fail the odd time and say it couldn't write the .exe

Now though it fails every time with the following message:

Error Executing script : BeforeAction

EInvalidCast

Invalid class typecast

Line : 1

Char : 1

Error in BeforeScript : VBScript, This Action did not execute.

As this is my development machine, the Visual Studio debugger kicked in and if I debug, what I see is in the attached image.

  
Can you help?

Hi Nick   
  
 What value does your VERSION\_MAJOR variable have? It’s probably best if you contact support at [finalbuilder.com](http://finalbuilder.com) with your project file so we can see what is happening and try to reproduce the problem here.
