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, 15.10, 16.20, 17.00, etc.) 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\17.00 and the 64-bit products will be installed in D:\Program Files\Teradata\Client\17.00. This follows the Windows convention. The same applies to a prefix like drive:\TTUProducts.
