To Vista User

If your operating system is Windows Vista or 7,
please install the external programs to the folder other than C:\Program Files
or otherwise disable User Account Control (UAC).


Problem common to the external programs (PC GAMESS, WinGamess, MSMS, Tinker and MOPAC) : 

     Facio.bat, which invokes external program, cannot be created
     in C:\Program Files, due to security reason. 

     If you change access permission of the folder 
     in which the external programs' executable resides,
     to full control, the common problem is solved.
     But it cannot solve the problem specific to TINKER. (See below)


Problem specific to TINKER :

     There is a very strange phenomenon in which initial molecular model 
     on the main screen is not updated to the optimized structure, 
     even if Tinker-MM3 calculation finished normally. 
     The cause of the problem is that the initial structure and the optimized structure
     are exchanged. It looks as if Vista played tricks on you.  
     Actually, this is attributed to the User Account Control(UAC)-File Virtualization of Vista.
