Uwe that was a pretty obvious answer and filled my inbox with two rather useless emails at the same time - so I hardly think you have the right to then criticise someone for dual posting.  I'd guess he didn't intentionally do it!

However your answer failed to point out the more obvious reason there is a problem - the path has a double forward slash in it WinBUGS14//System - under windows thats an impossible file name as far as I know.  I don't use WinBUGS (*or even windows) but rather than looking at file privs you should be trying to find how that path gets built.  My gut feeling is there will be a config file somewhere with a path that is C:/program files/WinBugs14 and another path that takes you from there to the files which is listed as /System/Rsrc/ - joining the two together and you get a double slash.  Probably take the leading slash off the second one - but not sure where you'll find the file.

Hope that helps - sorry I can't tell you where to look.
