Symptom  Action 
You  suspect  a  software 
problem. 
1.  To  determine  whether  the  problem  is  caused  by  the  software,  make  sure  that: 
v  The  server  has  the  minimum  memory  that  is  needed  to  use  the  software.  For 
memory  requirements,  see  the  information  that  comes  with  the  software.  If 
you  have  just  installed  an  adapter  or  memory,  the  server  might  have  a 
memory-address  conflict. 
v  The  software  is  designed  to  operate  on  the  server. 
v  Other  software  works  on  the  server. 
v  The  software  works  on  another  server.
2.
  If  you  received  any  error  messages  when  using  the  software,  see  the 
information  that  comes  with  the  software  for  a  description  of  the  messages  and 
suggested  solutions  to  the  problem. 
3.  Contact  your  place  of  purchase  of  the  software.
