"Unexpected error occured in code generator or linker".

I get this error every time I re-compile my .ocx project with binary compatibility.

I am attempting to re-compile the project onto the previous compilation which is also the same file I am maintaining binary compatibility with. I know this is not a problem with .dll projects as I have done two previously.

When I click on 'View Error Messages' I get:

LINK : fatal error LNK1104: cannot open file "\\Ex1\lanroot\group\Compiled\Components\ecsSearchBox.ocx"


This error occurs in the final stages of the compilation process when it is 'Writing OCX'.

Any ideas anyone?
