OK, I got this figured out now. IIRC, I had to re-create time sheets when I went from Win 7 to XP and now I know why.
First, you have to enable show hidden files in your win 7 machine. Here are instructions for doing so. Show hidden files & folders in Windows 7
HourGuard splits timesheets into a totally separate folder on the Win 7 machine. It also portions out the Accounts, Tasks, and Options folders into another separate location.
HourGuard itself resides in the folder listed in the migrate help here on this forum, but none of the data is in this folder.
File location for HourGuard on Windows 7
Paste your data files into these locations:
Folders named Accounts, Tasks, and Options
C:\ProgramData\NCH Software\HourGuard
Timesheets folder
C:\Users\username\AppData\Roaming\NCH Software\HourGuard
You will find the program file (hourguard.exe), uninstall.exe, and Help folder here:
C:\Program Files (x86)\NCH Software\HourGuard
Or, (I assume) on 32 bit Windows 7 installation, here:
C:\Program Files\NCH Software\HourGuard
This worked for me. Everything popped right up once I exited (full exit, use file - exit) and restarted HourGuard.
Biggest hurdle was finding the data folders because they were hidden by default.
