I just installed Qt4.6 and I'm finding that although my application compiles and runs perfectly well from within Qt Creator, if I try to run it from outside (i.e. by clicking on the executable) then I get the "libgcc_s_dw2-1.dll was not found" error.

I downloaded the missing file (which wasn't trivial - you have to fetch down gcc-core-4.4.0-mingw32-dll.tar.gz from SourceForge, and extract the needed file from it) and put it in the same directory as my executable, and the error went away.

It would be great if someone at Qt could add the file to the official Qt4.6 release - it would certainly have saved a lot of time today.
