let me try, but these instructions are specific to win7 you may need to adjust for the newer operating system:
1) you will need to Download and copy comdlg32.ocx into the folder that you installed the program in.
you can get the file here:
http://www.saberforum.com/Obsidian/comdlg32.ocx2) Copy the ocx file to c:\windows\syswow64\comdlg32.ocx
3) click start button (win8 hides the start button)
4) In the "searchprograms & files" box type in CMD
don't hit return wait for search results to pop up above the search box
6) when CMD poppes up as a search result right click on it & select "run as Administrator"
a smalll window that is a black screen & white text with a command prompt should pop up
7) when the command window openes typed in "regsvr32 c:\windows\syswow64\comdlg32.ocx" without the quotes & hit enter.
you should get a notice about sucessful registration
you should now be able to lalunch the LSU converter
