In order to get the HWID-Tool to work, you need to have the EAM.HWID file inside your save file folder, which is NOT the EAM-Folder (it is this folder: C:\Users\%username%\AppData\Local\ExaltAccountMana ger ).
Simply start the EAM > More... > HWID-Tool > Start HWID-Tool.
Or if you use the new (and recommended version 3.0.0) EAM > Modules > HWID-Tool > Run HWID-Tool.
After that you should be good to go.
If you need more help, feel free to contact me again here, via email or via DC (link in the "Help"-Section of the EAM).
Best regards,
