Hello
I need to update OCCT in our application from 7.7.0 to 7.9.0. I do not see 32-bit packages at https://dev.opencascade.org/release. Neither I see 32-bit third-party packages.
Is 32 bits still supported?
Thanks

One can barely find a good reason for using 32-bit version of Windows for a very long while (at least for the last decade), and the latest Windows 11 doesn't even have 32-bit version. The similar situation is with 32-bit ARM configurations on Windows, Android, macOS and iOS.
Hence, maintaining 32-bit builds for an application or framework doesn't look reasonable as long as you don't have to support some very old workstations for some reasons. I guess that you should be able building 32-bit version of OCCT on your own from source code, but probably nobody performs any testing of these builds nowadays.

Dear Nikolai, win32 is not popular nowadays. I totally agree with gkv. I was postponed delivery x32 version. Building of x32 version have no issue to build with old 3rd-party list available for 7.8.0. The reason why no-ready-to-use 7.9 - i had some trouble to build new 3rd-party for that bitness with the same versions of dependencies. I plan that task for later.
At the moment OCCT support and test x32 building, but I can't garantee that it will be available for long time. Please check option to move to the x64 version.
Additionally, if you must to keep on x32, OCCT3D offers service to preparing migration of new patches on previous version which will support x32. (For example, we can update 7.6 version with necessary bug-fixes and keep binary compatibility or some other criteria).
Best regards, Dmitrii.
