OK, thanks for all the advice, I've got depends producing output, it's too long to go into a post but you can get it here: http://pastebin.com/Pdb3rdY2. If anyone can help me make sense of this, I would be extremely grateful. It ends with 'failure to start process', which doesn't sound very promising.

Here's the end of the report:

Error: At least one module has an unresolved import due to a missing e
+xport function in an implicitly dependent module.
Error: Modules with different CPU types were found.
Warning: At least one delay-load dependency module was not found.
Warning: At least one module has an unresolved import due to a missing
+ export function in a delay-load dependent module.

Apologies for very long post, I tried using readmore, but it seemed to truncate it.

The posting limit seems to be 64KB (see What is PerlMonks post size limit? ), try using a pastebin, or maybe just copy/paste the most critical depends.exe output, the last error message and 50 lines around (before/after)

OK, previous post updated with Pastebin link, thanks.
