> When one of my users tries to start Vantage on her workstation, she gets the
> error "The license for the client executable has expired (4399)." According
> to Epicor support, this is caused by a corrupt installation. I have tried
> their suggestion of reinstalling. Even went so far as to go through the
> registry and completely remove any references to Progress and Vantage before
> reinstalling. Have also cleared out the temp and vntgwork (vantage temp)
> directory.

> This machine in question is running WinNT 4.0 SP6a. It is the only client
> doing this and it happens no matter who is logged in.
>
> Any other ideas? Anyone else seen the error before.

> Thanks for you help everyone.
