Hi TedGreen,
OK, i'll try to describe the procedure in detail. As I've a german Windows working on, you may find that the commands might be wrong translated, so in this case pick the closest match.
1.: Choose Start - Run command, enter regedit (not regedt32, which I had some problems with), klick OK. The registry editor should now show up.
2.: Locate the mentioned registry key in the left tree window and open it so that its contents is diplayed in the main window to the right
3.: Right-click on "Dependent Files". A menu pops up, choose "Rename" there. Type in a new name, e.g. "OldFiles" or so. Hit RETURN.
4.: Right-click somewhere in the empty space in the right window. In the pop-up window choose "New - Binary"
5.: The new Variable will show and you can enter a name immediately. Name it "Dependent Files".
6.: Double-click the Variable. A window shows up where you can enter the hex-values. Enter those from the old variable and click OK.
Thats it.
It might be worth a try if simply renaming the old Variable would already solve the problem.
Hope I could help.
