I removed Python(x,y) and the Python27 folder and did a full re-install. The 
problem persists.

Please verify that hdf5-vc90-mt.dll, zlib1-vc90-mt and szip-vc90-mt are present 
in c:\python27\DLLs .
Make sure c:\python27\DLLs is on your path.

I checked and hdf5-vc90-mt.dll is in c:\python27\DLLs and that folder is in the 
path. I didn't check the presence of the other two files. I tried re-installing 
using the explicit 'Run as admin' in the context menu after uninstalling, but 
no change there. Currently I reverted to 2.7.6.0 to get some work done, so I 
cannot check the presence of the other two dll's right now.

I had a similar issue on py2exe compiled executables.
On some machines the HDF dll is unable to load, while on others it works fine.

It turns out this particular version of the VC2008 runtime is required:

Hope this helps,

Last week I've uninstalled 2.7.6.0 again and installed the VC2008 runtime 
mentioned above and 2.7.6.1. Now it works, so it could be the solution. Thanks!

I confirm that the VC2008 (32bits) works for me too. Thank you so much Federico.
