licensed to Microsoft the core code, which was integrated into Windows 2000 and Windows XP, making ATM Light for Windows obsolete, except for the special case of support for "multiple master" fonts, which Microsoft did not include in Windows, and for which ATM Lite still acts as a font driver. ATM Light is still available for Windows users, but ATM Deluxe is no longer developed or sold. Users of ATM 4.0 (Light or Deluxe) on Windows 95/98/ME who upgrade to Windows 2000/XP may encounter problems, and it is vital not to install version 4.0 into Windows 2000 or later; affected users are encouraged to visit the Adobe web site for technical information and patches. Version 4.1.2 is fully compatible with Windows 2000 and XP (It will run on XP 64-bit, but because the installer doesn't work it must be first installed on 32-bit XP and then copied over to 64-bit XP). ATM installed on XP may prevent a system from entering standby - the error message indicates keyboard driver needs updating. Uninstalling ATM corrects the issue. Windows Vista is incompatible with both ATM Light and ATM Deluxe. Windows Vista can use Adobe Type 1 fonts natively, making add-ons like ATM unnecessary. The latest version of ATM for Windows 3.1 is 3.02. There was no ATM Deluxe for Windows versions prior to 95. Acrobat Reader, starting with version 2.1, installs a version of ATM for its own use, referred to as a Portable Font Server, but there is no control panel or other user interface for it. It is therefore unsuitable for the tasks which most people need to install ATM for. Other operating systems Adobe Type Manager was also made available for a select few PC operating systems available during the early 1990s, including NeXTSTEP, DESQview, and OS/2. Unlike the Windows and Mac versions, these versions of ATM were bundled with the OS itself. There were also ATM versions for extremely popular DOS applications, the most notable being WordPerfect 5.0 and 5.1. This incarnation of ATM, made by LaserTools was named PrimeType in the United States and Adobe Type Manager for WordPerfect elsewhere. An alternative to ATM for WordPerfect 5.1 was by SoftMaker. WordPerfect 6.0 and newer included its own Type 1 system, making third-party solutions obsolete.
