Confusion about MacOS downloads

[pwhirley]

I am trying to install PXPlus on my MacOS for the first time. I'm running MacOS Tahoe 26.5.  On the downloads page I find the row that says "MacOS - M1 MacOS Sequoia v15.4 64 Bit.".  It shows a date of 2026-May-20 and size of 33MB.  Sequoia doesn't match Tahoe, but I figured it might work.  The file download button says "pxp2300-0000-MM1-64.taz".
The actual download is not a TAZ but a GZ, which shouldn't make any difference.  It is, apparently, automatically extracting when it lands on my system.
Once there, I attempt to run the executable and it fails every time:
zsh: exec format error:"
Is this a problem with my OS version or am I doing something wrong?  If it is an OS version problem, when with a MacOS build be available for Tahoe?

Thanks - Phil

Should I have put this in a different area?  Where does this question belong?  I'm trying to get a product to download and install on MacOS.

The v23 PxPlus was actually built on Tahoe. The downloads page was not updated correctly and we will fix that.

The file is technically a TGZ file but has the TAZ extension.

If you do a Open With and select the Archive Utility it will extract the contents. You can also from the terminal extract it with the command

tar -xzvf pxp2300-0000-MM1-64.taz
