Re: [Openexr-devel] RgbaOutputFile error on MSVC2005?

[Ger Hobbelt]

Hm... did you try running one or more of the test apps included in
OpenEXR - to see if those do not turn up this error? (This might be
something due to not having the right Microsoft DLLs around or
something of that nature.)

Also check your executable/DLL using the Dependency Walker tool (
http://www.dependencywalker.com/ ) to see if any DLLs are listed as
missing (red lines). (Note: some system DLLs optionally delay-load
other system DLLs, which can show up in red - the point is that none
of the non-Microsoft DLLs and the binary itself should have
_immediate_ children listed as not available in there - unless such is
intentional.)

In case of further doubt / worry, fetch the sources (which include
project files) and compile/build the libs + tools on your own system.

My 2 cents at this moment...
