This morning, I was setting up a test machine with WebSphere Commerce 6.0 Express. I proceeded with typical installation. The installer kept giving error message about Windows user ID password – “User password entered is incorrect”.
This was most frustrating to say the least. I was entering the correct user ID and password. The user belonged to the Administrators group.
The solution was to install DB2 first. DB2 installer most probably adds the correct rights to the user.
Then, I did a custom install of Commerce. Typical install was not possible since DB2 was already installed. Things went smoothly.
