[WriteLog] Trouble installing contest module

[Bill Turner]

Just started using Writelog again after an absence of a few years. Got
almost everything working thanks to AA5AU's excellent tutorials, but
have one issue left. 

I installed the SM6SRW module with no problem using the Legacy
Installer Helper as Don said in his tutorial, but when I tried to
install the DL1EFD module, I get an error message saying the .dll
files are "not registered", whatever that means. The two contests I
tried to install do not appear in the list of available contests. 

I tried installing it with and without the Legacy Installer Helper
with the same result either way. 

Running Windows 10 32 bit system. Could this be a compatibility issue
with Windows 10?

Suggestions? Thanks in advance,
