Die TAA bietet im rahmen von TAA 26.00 die Kommunikation zwischen 32 Bit zu 64 Bit Prozessen und Umgekehrt. Dazu hier eine aufstellen der Möglichkeiten welche von der TAA aktuell nicht/unterstützt werden:
| ITyp | Aufruf | Verhalten |
| DLLCLR | 32 Bit | Supported |
| DLLCLR | 32→ 64 Bit | Supported |
| DLLCLR | 64→ 32 Bit | Supported |
| DLLCLR | 64 Bit | Supported |
| sonstige | 32 Bit | Supported |
| sonstige | 32 → 64 Bit | Condition |
| sonstige | 64 → 32 Bit | Condition |
| sonstige | 64 Bit | Condition |
