Teradata Tools and Utilities (TTU) Products can now be installed at a location provided by the user. All products of the same release (for example, 16.20, 17.00, 17.10 and so on.) must be installed at the same prefix.
For example, if the prefix is a drive (for example, D:), the 32-bit products will be installed in D:\Program Files (x86)\Teradata\Client\17.10 and the 64-bit products will be installed in D:\Program Files\Teradata\Client\17.10. This follows the Windows convention. The same applies to a prefix like drive:\TTUProducts.
