db2setup on Windows – Repair Option
Sometimes with DB2 on Windows installs just don’t go right. There is a repair mode on db2setup that can help.
There are a number of problems that can manifest. One is a completely successful install on Windows, but the menu items just don’t show up under “all programs” on the start menu.

I had run commands that should have set DB2INSTANCE already, so it wasn’t just a profile problem. While db2val completed successfully, I still chose to do a repair option.
Invoking a Repair
Generally I’ve noticed that a repair operation will often require a reboot, even if the original install did not. Also, note that this kind of action would require the instance to be down if you performed on a system where DB2 actually worked.
