How to use both 32-bit and 64-bit versions of the Oracle Client in MapInfo Professional

Product featured: MapInfo Professional™
There should be no problem for users running both MapInfo Pro 32-bit and 64-bit on the same machine.

Users will need to have 2 instances of Oracle Instant Client - one for each "flavor" of Professional.
32-bit Pro will need 32-bit Oracle client and 64-bit Pro will need 64-bit Client.

Here is one possible installation example:
C:\Oracle\instantclient_12_1 - for 32-bit Oracle Client
C:\Oracle\instantclient_12_1_64 - for 64-bit Oracle Client.

Each of these folders must have the tnsnames.ora file with Oracle connection info.
