During a Toad for DB2 installation, the install fails with a failure in creating DB2 global registry.
The following error appears in the install log:
'An error occurred while initializing the Profile Registry. The return value is "-2029059760". Contact your technical service representative.'
This is an IBM issue and there is an APAR JR26658 for this :
The reason of failure is that an incorrect registry HKLM\SOFTWARE\IBM\DB2\InstalledCopies\DB2V8 was created by the installation of v9 Info Center on the system with v8 DB2 installed.
Remove the incorrect registry
HKLM\SOFTWARE\IBM\DB2\InstalledCopies\DB2V8 from the system.
