Is Windows 10 supported for the Vantage 8 Client?

Client got some new machines and getting odd random errors only on those new machines. Quitting, and restarting client works again for a while and then random errors:
Errors such as “Key not found” “Parameter name key”

I’m not a big fan or Windows 10 but haven’t had too many issues running V8.
A few things I might start with to try and resolve instability in Win 7, 8 or 10.

V8 client shortcut properties - Compatibility sheet

  • run in compatibility mode WinXP SP 3
  • disable themes
  • run this program as administrator

Windows - turn off unneeded applications & services, disable themes, set screen save to blank screen, etc…

AntiVirus - make sure you’ve excluded the V8 Client directory

Errors such as “Key not found” “Parameter name key”
And when I see these, I get in the habit of regularly clearing the cache folder(s)

  • which unfortunately is still a manual process in V8
    Go to the folder c:\programdata\epicor\ and delete any subfolders like 8.03.409c, etc…
  • c:\programdata\epicor\8.03.409C
  • c:\programdata\epicor\8.03.410

These are some places to start at least, even if you end up having to do something else.


Hello Mark,

Were you able to find a solution for this issue?


It’s been so long, I don’t recall
