Moved to Windows10- lost all pointers

[Deeter]

I'm running Hoster on Bootcamp on a Mac Powerbook. I had to upgrade the MS OS to Windows 10 so, after reading several posts on the forum, I uninstalled Hoster while connected to the internet. After the upgrade to Windows 10, I reinstalled the latest version of Hoster that I had already downloaded and used previously. When installing, it never gives an option to select a folder for a previous installation. So instead of the install calling all the files, songs, etc. that were installed in a directory C:\MTU ti creates a default data folder under C:\ProgramData\mtu.com\Hoster. So that loses all my songs, instabuttons, etc.
I tried resinstalling several times but don't see how to specify where the program should install. How can I "reclaim" all my saved info without having to re-index everything? I literally uninstalled, upgraded to Windows 10, then need to reinstall with no other changes having occurred on the PC.
Thanks
