System Workbench for STM32

Hi,
I downloaded the installer again the latest.run, but this time I also downloaded the md5 signature, here is what I got:

MD5 (install_sw4stm32_macos_64bits-latest.run.md5) = aaf9b4bc935a47e6fc367417997bdd21
MD5 (install_sw4stm32_macos_64bits-latest.run) = 1db5de6ddd6e7458dcc6ad370121eff5

In my understanding, these two should match, do they? That's the purpose of the md5 sum .... no ???
In my perception, it's already screwed up, even before any attempt to install...
Can someone correct me, if I'm wrong?
Kind regards,
Francisco
