Problems installing DB2 on Windows Vista

Installed DB2 Express on Windows Vista (Business 64-bit) yesterday, and hit a bunch of errors at the end of the install.

Specifically:

• An error occurred while initializing the Profile Registry.
  
  The return value is "-2079391743". Contact your technical service
  representative.


• An error occurred while setting the registry key "SOFTWARE\Microsoft
  \MSDTC\XADLL\C:\Program Files\IBM\SQLLIB\BIN\DB2APP.DLL" to "C:
  \Program Files\IBM\SQLLIB\BIN\DB2APP.DLL".


• One or more errors occurred while committing the changes to the
  user "DB2". Create or make any changes to this user manually.


• An error occurred while creating the instance "DB2". The return
  code is "-1918". Create the instance manually using the command
  "db2icrt".

So after some research, here is how to fix it:

• Create DAS user (for example db2admin) via Windows as an Administrator


• Execute "db2admin CREATE /USER:db2admin /PASSWORD:*password*"


• Execute "db2admin SETID db2admin"


• Execute "db2icrt -u db2admin DB2" (where DB2 is the instance name)


• Set System Environment Variable "DB2INSTANCE" to your instance name


• Set System Environment Variable "DB2PATH" to "C:\Program Files\IBM\SQLLIB"


• Reboot your machine


• Follow http://publib.boulder.ibm.com/infocenter/db2luw/v9r5/topic/com.ibm.db2.luw.qb.server.doc/doc/t0011930.html to add yourself to DB2ADMNS


• Execute "db2set db2comm=tcpip"


• Start your DB2 instance
