Hi Mark,
I had the same problem - there's a batch file in the RWT download, run that and it should sort the problem. You might need to run under Administrator.
If that doesn't cure it I have an email here from Mike Simpson describing how to do it manually. Which in my case, I needed
'Hi Antony,
The superpicture2.ocx module is only used to display either the thumbnails of stock or the .tgpcdx files in the viewer. I had to use this module because it is the only one I know which will display the new large size .tgpcdx files.
Others have seen the error message but in their case running the batch file has always fixed the problem.
The only thing I can suggest is that you open a CLI window as administrator (go to the Start menu and in the bottom box enter cmd then press ctrl+shift+enter
A CLI window will open with Administrator in the top border.
At the prompt type
regsvr32.exe "c:\Rail Utilities\RW_Tools\superpicture2.ocx"
and press enter
You must of course alter the path if your RW_Tools path is different.
That should fix it.
Mike'
Hope this helps,
