Thanks for this tool. I run Vista Ultimate and after reading the posts i have got it running the first time I installed it.

For those running Vista and experiencing problems try running it in XP service pack 2 mode.
Right click RTMViewer click on properties (at the bottom of the dropdown popup) click on the second tab "compatibility"
ensure the run this program in compatibility mode for "windows XP (service pack 2) is ticked then click on apply/OK and it should work.
Hope this helps anyone having problems
