IGLN02C.DLL !!!

Several days ago, I installed and configured an application with Informix 7.20 SE. I am now trying to install 6.0 SE and an application for that configuration. When I try running dbImport or even try to start the application, I receive the following error: Error Starting Program A required .DLL, IGLN02C.DLL, was not found. This is an SE 7.20 .DLL. Why is SE 6.0 trying to call it??? I have this machine configured with two bootable environments: REM ---[ For SE 7.2 App ]--------- REM SET PATH=C:\\WIN32APP\\INFORMIX\\BIN;C:\\WINDOWS;.... REM SET INFORMIXDIR=C:\\WIN32APP\\INFORMIX REM SET INFORMIXSERVER=LOCAL REM SET DBPATH=C:\\MYDB REM ---[ For SE 6.0 App ]--------- SET PATH=C:\\INFORMIX\\BIN;C:\\WINDOWS;.... SET INFORMIXDIR=C:\\INFORMIX SET DBPATH=C:\\MYDB As you can see, both configurations are discrete. To prove this to myself, I have another machine on which I have successfully implemented this. Each boot supports the respective DBMS engine and application. I have completely scrubbed the troubled machine of SE 7.2 including any references to it in the Registry and have removed C:\\WIN32APP\\INFORMIX. But the SE 6.0 engine still looks for this 7.20 .DLL. IGLN02C.DLL no longer is on my machine. I have unsuccessfully performed global text searches on all files within the following directories for IGLN02C.DLL: WINDOWS, WINDOWS\\SYSTEM, C:\\INFORMIX, C:\\INFORMIX\\BIN, C:\\MYDB, and probably several other places that don't come to mind right now. I've always considered myself fairly resourceful when looking for these kinds of problems, but this one's got me stumped!!!!!! Any help would be greatly appreciated! Mark D.
