I would suggest downloading the installer and installing again. If the problem persists try the steps in this troubleshooting guide.

Update The 32 bit Windows installer for OpenStudio 1.10.0 is broken, the openstudiomodelhvac.so file is corrupt. I tested the 1.10.3 and 1.10.4 builds and these both worked for me (both the OpenStudio Application and SketchUp plug-in worked).
