Download:
In the webpage: http://www-933.ibm.com/support/fixcentral/legacy/
With parameters "Information Management" - "IBM Data Server Client Packages" - Custom version and platform
Then write *odbc_cli* in Id Fix
Download the latest fix pack (in my case "IBM Data Server Driver for ODBC and CLI (Windows/x86-64 64 bit) V10.5 Fix Pack 7")
Installation:
Copy zip into C:\Program Files\IBM (if not exist, you must create the folder)
Extract it
In cmd:
Execute "cd C:\Program Files\IBM\{uncompressed driver folder}\bin" (by default "clidriver")
Execute "db2cli install -setup" for install. If you need uninstall, exec "db2cli install -cleanup"
If you need install it for pointing to 32 bit IBM DB2 ODBC driver for your 32 bit application in a 64-bit environment, read this documentation: http://www-01.ibm.com/support/docview.wss?rs=71&uid=swg21384435
Note: in version 9.5.* the command changes:
Install: db2oreg1.exe -i
Uninstall: db2oreg1.exe -u
In my opinion, I recommend download IBM Client i Access with custom installation, selecting only "ODBC" and "OLE DB Provider"
You can download it by ibm public ftp: public.dhe.ibm.com (port 21)
