[WriteLog] 12.46D Upgrade Will Not Install

[nosatisfaction]

This is a re-post of my previous report same Subject hopefully with the formatting fixed:
On January 9, I installed the 1246D update.  At the time, my computer was 
running Win 7 Pro.  Yesterday I updated the computer to Win 10 Pro 1909.

After the Win 10 install, the first I did was to see if WriteLog still worked. 
It did, but the bandmap was blank.  Today I uninstalled WriteLog, reinstalled my 
latest full version, 12.09F, and proceeded to reinstall wl1246Dmsiupg.exe.  It 
fails with the message:

The file 'Arrl222andUp.dll' cannot be installed because the file cannot be found 
in cabinet file 'Wl12Full.cab'.

So now I am stuck back at Ver. 12.09F but at least I've got the bandmap.

Seems very peculiar that the 12.46 update ran fine a week ago on Win 7.  I will 
add that I had to place a copy of the cabinet file in the same folder as the 
12.46D upgrade executables to get as far as missing the dll.  Prior to that, the 
routine said it could not find the cabinet.

Added note:  I don't think Arrl222andUp.dll was ever present as the contest does not 
appear in the list when selecting "New Log" starting WriteLog.
