This is very strange. With the setup described, there is no way I can get these files to be written to %AppData%\ZTreeWin.

Here is my test setup:
- Windows 10, 64-bit, 21H2
- Installed ZTreeWin using the downloaded Release ztw22x64.exe.
- Changed the install directory to "C:\Program Files\ZTreeWin".
- Added my key.
- Replaced all files with those from ZTW24204.ZIP
- Deleted directory %AppData%\ZTreeWin.
- Ran ZTreeWin from the installed shortcut on my Desktop.
- Made an Alt-F10 change, added a new F9 Menu, and created a Treespec history item.
- Quit
- Using a ZTree NOT installed under "C:\Program Files":
- Moved the %AppData%\ZTreeWin\ZTW.INI, ZTW.ZAM and ZTW.HST files to "C:\Program Files\ZTreeWin"
- Deleted directory %AppData%\ZTreeWin.
- Ran ZTreeWin from the installed shortcut on my Desktop.
- Made an Alt-F10 change, added an F9 Menu item, and created a Treespec history item.
- Got the error previously described on ZTW.ZA$
- Quit
- A new %AppData%\ZTreeWin directory was created, but the only file in it was ZTWIN.BAT
- The existing "C:\Program Files\ZTreeWin" ZTW.HST and ZTW.ZAM files were not updated.
- Running it again with the now existing %AppData%\ZTreeWin directory has same result.

Now here's what's REALLY bizarre! The "C:\Program Files\ZTreeWin\ZTW.INI" file was updated! Again, this is with ZTree run as Non-Admin. I couldn't believe it, so I did it again. Even rebooted the computer to be sure it wasn't due to some latent artifact. Same result.

It so happens that, just to be sure I had all the steps correct, this was the second time I ran through this same install and update. But rather than uninstalling the previous version, I had first renamed the previous install to "C:\Program Files\ZTreeWinX".

So just for grins I changed the Desktop shortcut to that directory and ran it. But in that case Alt-F10 config would NOT update ZTW.INI, just as it had not before, and again it was not written to
%AppData%\ZTreeWin.

So thinking it may be some Registry entry pointing to that new directory, I renamed the new install to "C:\Program Files\Zxxx", and changed the shortcut to point to it. Again, ZTW.INI was updated! I changed the old install directory to "C:\Program Files\ZTreeWin" and again the same shortcut to point to it, and the ZTW.INI file was NOT updated.

So for some reason Windows is allowing the identical ZTW_CFG.EXE program permission to update the ZTW.INI file in the new directory, regardless of its name, and not allowing it in the old directory, regardless of its name. I've checked all NTFS permissions for the directories and ZTW_CFG.EXE; they are all identical.

If anyone has a clue as to how or why this could be happening, please share.

In any case, no matter what I do, these three files are never written to %AppData%\ZTreeWin if they exist under "C:\Program Files" but do not yet exist in %AppData%\ZTreeWin. The only file written there is ZTWIN.BAT.

Kim, in case there is some variable not yet accounted for, I will email you a ZIP of my installation directory.
