Attempts to install IBM Rational Test Workbench on 64-bits Linux result in error "cannot open shared object file ... ".
Which error message occurs depends on which library files are missing.
cannot open shared object file: No such file or directory
bad ELF interpreter: No such file or directory
IBM Installation Manager is a 32-bit application. 32-Bit library files are absent in the 64-bit host operating system.
Resolving the problem
Install the missing 32-bit libraries before running Installation Manager.
See the System Requirements for IBM Installation Manager for the supported operating systems and details of 64-bit operation.
