It is because 32bit ODBC drivers dealing with 64bit TD tools and utilities. Most of the times while installing TTU it sets the 64-bit TTU directory path along with 32-bit TTU in "PATH" environment variable. Removing 64-bit dir path variables from "PATH" resolves the issue.
64-bit path variables contains %\Program Files\% in path and 32 bit path variables contains %\Program Files (x86)\% in path.
