IBM DB2 ODBC DRIVER :: SQL1390C The environment variable DB2INSTANCE is not defined or is invalid

Question

I've followed several guides online and I cannot install IBM DB2 ODBC DRIVER on Windows.

I have downloaded the driver from IBM and installed (which was quite a roller-coaster).

If I follow guide1 or guide2 the result is the same:

SQL1390C The environment variable DB2INSTANCE is not defined or is invalid

Note: this is my C:\Program Files\IBM folder and as you can see there is no bin folder

Not sure if db2oreg1.exe -setup is still mandatory, things might have changed.

So I uninstalled the universal_fixpack and installed the client and the installation was successful.
