Compatibility of 32-bit VB6 Applications with 64-bit SAPI

[tmighty2]

ps: I posted the reference that I used in TwinBasic to chatgpt, and it said that the library that I'm using, identified by the GUID "C866CA3A-32F7-11D2-9602-00C04F8EE628", is part of Windows' built-in speech capabilities, specifically tied to the Speech API.(SAPI).
This is what I see when I double click the reference in TwinBasic:

[ LibraryId ("C866CA3A-32F7-11D2-9602-00C04F8EE628") ]
[ Version (5.4) ]
[ Description ("Microsoft Speech Object Library") ]
Library SpeechLib

    ' Original type library: C:\WINDOWS\System32\Speech\Common\sapi.dll
    ' NOTE: Offsets and lengths calculated for current Win64 target.

I checked the customer's registry, and it is found:

[HKEY_CLASSES_ROOT\CLSID\{0655E396-25D0-11D3-9C26-00C04F8EF87C}\TypeLib]
@="{C866CA3A-32F7-11D2-9602-00C04F8EE628}"

I see that the version of sapi.dll of the customer's computer is newer than mine, but SAPI exists since many years, and I find it highly unlikely that a change to it was introduced which in turn would cause an incompatibility.
