PGAdmin Installation x86 or x64 which is it?

Hi,

OK so I've downloaded the very latest Enterprise Data Base PostgreSQL
x64 installer for Windows 10 which installed very easily.

First thing I noticed was PGAdmin 4 was VERY slow until after I did a
reboot. I'm sure this is just one of those things, but noting it anyway.

Right so as to this problem

I open PGAdmin 4 and it complains that it is version 1.2 and I need to
upgrade to 1.3, so go to the download page

https://www.pgadmin.org/download/windows4.php

Click the link and there is only a x86 version.

Trouble is the EDB installer has installed PGAdmin in "C:\Program
Files\PostgreSQL\9.6\pgAdmin 4" which is a x64 directory.

I really don't want to have two copies of PGAdmin 4 on my computer, or any
computer for that matter, so what is the correct way to deal with this
situation?

Will a x64 version be made available or has the version installed with the
EDB installation been installed into a x64 folder when it is really an x86
application and should therefore be in a "C:\Program Files (x86)" folder.
Which would be very confusing...

Simply put, how do I upgrade my PGAdmin 4 without having two copies on the
computer?

Thanks and best regards
