When do you use the 32-bit or 64-bit version?

Always use the version compatible with the Java Runtime Environment (JRE) used by ARIS.

If you start locally installed clients, that is, not as a download client, an internal 32-bit JRE (bundled) is automatically used regardless of the locally installed JRE. Therefore, please use the 32-bit version of SAP JCo 3.0.x for ARIS clients. Copy the file sapjco3.jar manually or by software distribution to the directory <ARIS installation directory>\client\lib.

Regardless of the operating system, download clients always use the local 32-bit version JRE when executing. The file sapjco3.jar is distributed automatically if SAP JCo is made available. The file and sapjco3.dll need to be copied to the specified Windows directory. Copy the version of SAP JCo 3.0.x that is compatible with the operating system.
