All,
The "setup /SI -sms /Nodisp" flavour works like charm for EPSON Perfection V700/V750( epson376574eu.exe ) for me.
I extracted the installation by copying from %temp%, resulting in the files below:
LIB (folder)
Setup.exe
Es63.inf
EsNet.cab
ResNet.cab
ResLang.cab
PerV700.cab
ModUsd.cab
es63.cat
EsCore.cab
ModExt.cab
Setup.ini
Where the es63.cat file contains the signing with a certificate valid till 06-07-2013.
I re-signed this es63.cat file with a custom made company certificate, using step 4 of the manual as stated here:
Before starting the silent setup on the client, I import our certificate into the ROOT and TRUSTEDPUBLISHER store:
certutil -addstore ROOT "C:\Temp\Epson_v700\Duiker-ICT.cer"
certutil -addstore TRUSTEDPUBLISHER "C:\Temp\Epson_v700\Duiker-ICT.cer"
