During the installation I get these error messages:
*****
SQL1390C  The environment variable DB2Instance is not defined or is
invalid

An error ocured while loading the command "C:\Program
Files\IBM\SQLLIB\bin\db2.exe CREATE TOOLS CATALOG SYSTOOLS USE
EXISITING DATABASE DWCTRLDB FORCE" to initialize and\or migrate the DB2
tools catalog database.  The return value is "5104".

DB29501E DB2 has detected an inconsistent environment.  Please
investigate the following: "DB2Instance: -2029059916"

*****
I checked to see if my services are running and all but these two are
started: DB2Warehouse Server and DB2 JDBC Applet Server

I also updated all DB2 services to use my local account which is a
domain account with admin privs. on my machine
