By chance during my development work today I found out that the string "Enabled" is assigned to resource ID number 61477 (0xF025). Such a high resource ID number is usually assigned to certain MFC error (debugging) strings for exceptions. The define AFX_IDS_INVALID_ARG_EXCEPTION in afxres.h
is associated with 0xF025. There are not many webpages about AFX_IDS_INVALID_ARG_EXCEPTION.
From what I have read, it could be that a standard library (DLL) installed on your computer needed by UltraEdit is corrupt or has the wrong version. You should first uninstall and then reinstall UltraEdit. Your configuration files are not deleted during this process, just the UltraEdit program files are reinstalled. Perhaps that solves already the problem. And please also check the value of environment variable PATH. The first directory of PATH should be the Windows system directory. Some applications add their program paths during an installation to the beginning of the existing string value of PATH instead of adding themselves to the end.
