My V8 is online so as far as I am aware there is no database or Odoo application files on my PC for V8.
V8 online has been running for one year.
So, yes I have two instances & two databases but one is online.
V9 community was installed on my PC yesterday.
I followed the link provided by Odoo: https://www.odoo.com/fr_FR/page/community
Downloaded the windows file ( Odoo_9.c latest.exe ) ran the .exe & specified Engish language/ UK as Country.
This installed the following onto my hard disk: PostgreSQL, Server, Service, Thirdparty and Uninstall. But strangely, no program launch icon for Odoo anywhere ! ?
Next, I installed the modules I need.
About 3/4 way through installing the modules I got a "cannot connect" error which I assumed to be as a result of my very poor internet connection but it would still not re-establish the connection even after restarting the router.
So I used the uninstall utility, re-booted the pc & ran the Odoo exe again. When complete, the modules I had already installed were still there !!.
Installed the remaining modules & all looked good . I opened a few of the apps including accounting & inventory just to have a look. This morning I get an error if I open any apps including modules (apps).
Here is the full error message for apps:

It is not possible to say anything without reasonable information. How did you install these different versions? Do you have 2 separate database instances and 2 separate Odoo instances? Did you properly specify the corresponding .conf files?
