Do the following steps BEFORE looking at the above link. If your problem is solved then no need to look further.
1) Install the 32-bit version of K-Lite (Use FULL version) and,
2) *Install the 64-bit version of K-Lite (Use FULL Version)
*Only install the 64-bit version if you have 64-bit Windows. To clarify, 32-bit only for 32-bit Windows but BOTH for 64-bit Windows.

Among other things, the 64-bit version added THUMBNAIL support for pictures. I don't know the full extend of its support but it doesn't hurt to add it even if you don't need it.
3) Install FASTSTONE regardless of whether you use it:
4. Ensure VIDEO DRIVERS are the latest. (must be for proper version of Windows and your graphics chip/card from Intel, AMD or NVidia as suitable. Choose "AUTODETECT" to be safe.)
