Some accounting and inventory systems (e.g., Visual FoxPro-based, or old Delphi apps) have hardcoded calls to unrar.dll version 5.61 32-bit. Upgrading the DLL breaks the entire backup routine. The "exclusive" 5.61 is the only version guaranteed to match the API hook.
While 64-bit computing is the standard for consumer PCs, the 32-bit variant of WinRAR 5.61 fills vital niches across several technical industries. Legacy Infrastructure and Industrial Automation

One of the headline features of version 5.61 is the improvement to the "Delete archive" extraction option. In previous versions, if you started extracting from a non-first volume of a multi-part RAR archive (e.g., part2.rar instead of part1.rar ), the program would ignore the command to delete the archive files after successful extraction. With WinRAR 5.61, even if you begin extraction from the second, third, or any subsequent volume, the software intelligently finds the first volume and, upon successful extraction of all files, proceeds to delete volumes of the archive. This fix resolved a long-standing user annoyance and streamlined the process of handling split archives.
