@TheQuinbox Two things, if I may raise them. First, I strongly suspect that opening is actually, and in the real world, much faster than before. An 11.8 million word file on a very old system (i3 2120 with 4 GB RAM and an old hard drive), takes less than ten seconds. I may be wrong, I didn't try this file with the previous version, but I don't think I am, I think this is a huge jump. Secondly, on a different machine, running Windows 10 LTSC, I'm getting this. No download: Update is available but no matching download asset or signature was found.

OK
when I check for updates. How do I diagnose this, if I may ask?
