While Talisman Digital Edition ran on WinXP when first released, subsequent updates (and the initial release on GOG) were limited to Win7+. However it is possible with a little work to get Talisman running under WinXP again.

What you need (aside from Talisman DE itself):

* A hex-editor with good search-and-replace functionality (I would suggest the free HxD).
* A copy of the bcrypt.dll and mbedtls.dll files from ReactOS (download the full distribution and extract just those 2 files).
* A copy of the advapixp.dll and kernelxp.dll files from Xompie.

Install Talisman Digital Edition but do not run it yet.

Make a backup copy of the following files (HxD will do this also, but always best to take extra precautions):
- Talisman.exe
- Galaxy.dll

Copy the advapixp.dll and kernelxp.dll files from Xompie into the Talisman folder.
Copy the bcrypt.dll and mbedtls.dll files from ReactOS into the Talisman folder.

Edit Talisman.exe:

Change bytes $188 and $190 from $06 to $05 (see screenshot).
Replace all occurrences of "kernel32" with "kernelxp".

Edit Galaxy.dll:
Replace all occurrences of "kernel32" with "kernelxp".

Talisman should now run after a few seconds delay on startup. The changes made will *only* affect Talisman itself, with no system-wide impact. Online multiplayer has not been tested since that would require Galaxy (which even if it could be "persuaded" to run under WinXP would probably complicate matters greatly) but DLCs can be added with no issue (the main .exe file isn't changed).
