You'll have to go into the Windows registry and manually delete any Reason files that are still there. The Registry keeps certain files there, even after uninstalling.
This is from an old email I had: (I added the Reason name in there):
=======
Now, I recommend that you configure Windows to show all files and then search
for the Reason files and delete them.
Configure Windows to show all files:
1. Double-click the My Computer icon on your Desktop.
2. Click the Tools menu in the top toolbar and then click Folder Options.
3. Click the View tab.
4. Uncheck "Hide file extensions for known file types."
5. Under the "Hidden files" folder, click "Show hidden files and folders."
6. Click Apply, and then click OK.
Now, search for and delete all Reason files/folders.
1. Click Start, Search, and then select "Files or Folders".
2. "Look in" is set to "All drives" or to C:
3. Make sure that "Search subfolders" is checked. (You may have to click the
"Advanced Options" arrow to display this.)
4. Click All files and folders.
5. In the "All or part of the file name box" type--or copy and paste--the
following text:
Reason
6. Click Search.
7. Delete all files and folders that are found by the search.
Finish by cleaning up the Registry:
CAUTION: We strongly recommend that you back up the registry before you make any
changes to it. Incorrect changes to the registry can result in permanent data
loss or corrupted files. Modify only the keys that are specified. Please see the
document linked below for details on making a backup of your registry:

Find.
4. Press the Delete key on your keyboard and click Yes to confirm.

removed.
