Side-by-side installation of CA Plex r7.0 with CA Plex r6.1 and r6.0

The CA Plex r7.0 unmanaged C++ runtime is backwards compatible with CA Plex r6.1 and r6.0. This means that C++ functions generated with CA Plex r6.0 or r6.1 can be used with CA Plex r7.0 version of the runtime without needing to be recompiled.

Note: There is no forward compatibility - do not use the CA Plex r6.0 or r6.1 runtime with CA Plex r7.0 functions because runtime errors will occur.

The 7.0, 6.1, and 6.0 C++ runtime DLLs have the same names. For example, ob600lc.dll, ob600nwi.dll and so on. When the CA Plex install modifies the system path, the Plex 7.0 Bin folder is put at the beginning of Path statement. This means that, by default, both 6.0 and 6.1 WinC applications will run with the newer 7.0 WinC runtime DLLs on your PC.
