Can you verify you have .NETv3.5 installed on your system?
Did you ran Windows Update lately?
Can you try to re-install the VC++ binaries: http://svn.mapwindow.org/svnroot/InstallationProjects/4.8/Documents/vcredist_x86_2008.exe
And can you download dependency walker: http://www.dependencywalker.com/ and drop the ocx on it.
It should not report any missing dlls.
