I recently bought a new computer with Windows 10. I installed MSTS simply to set up the registry. This installed on the OS C: drive. All my MSTS programs, routes, etc are installed on a different drive on which I copied from the older win 7 computer. However when I instaledl a new download of Switchlist Gen it installs to the OS ©. I do not see a choice anywhere to change the path to a different drive. My Open Rails picked up the new drive and works fine. How can I get AG and Activity Master to see the correct path?

It is a rather complex path.

I'm a bit slow in replying - hopefully you got things figured out.

When you click "ChooseActivity (.csv) File" it gives a dialog box to locate the file - which of course will be in your route installations, wherever open rails looks for them.
