I am not sure, I downloaded several other software packages, made several updates to them (including Windows 10 updates) - all problem free. Even, I have a download from Silverfrost (FTN v8.61 PE) from March 2020, I can install it problem free!
A few days ago I manually updated some DLL´s and PLATO as published by Paul and after these updates I downloaded and tried to install this new FTN95 download
(over the top of the existing one from March 2020). I suspect - it could be a problem.
So - the question is: Should I un-install the March 2020 installation first and then try to install the yesterday´s download? Is in the yesterday´s download of FTN95 ALL updates included (including PLATO v5.3.0) as were published in the UPDATES by Paul, or - when I install this new (yesterday´s download) pack, should I manually update the DLLs and PLATO v5.3.0 again?
