Version 7 does not copy to applications correctly.

I have version 6 on MacOS 10.15. I downloaded version 7.0.4.
Everything went ok until during installation I copied it to the
Applications folder.
Instead of replacing version 6, it began to be copied to
a folder in Applications, apparently randomly selected.

Instead of replacing version 6

… and you are sure you clicked “Replace existing version” when being asked? If yes - file a bug report, though this never happened on my macOS test system (changing the version very frequently).

The problem was that the “Replace…” message did not appear
for several tries. Then it did, and I could correctly install it.
