Installation Source Registry Key
Here's a trick that I use with Vista. In Control Panel > Programs & Features > View > Choose Details. Tick the box for Source to see the origin of the install. I think that's what you're looking for, Marcus. Also tick Location to see where the installed program now resides. Setting up those columns is a little bit tricky. Make sure to click the checkbox entry to highlight it, then also key-in a numeric column width.
Jul 27, 2009. The path of the setup source in the Windows Registry during installation. If the key is listed there check the drive letter and path that is listed.

Then, you can also use the Move Up/Down buttons to choose the order the columns are displayed. It's not hard. Btw - you can also right-click the column header bar instead of using View > Choose Details.
