Run manually with logging before deploying silently:
epskitx64.exe /log "C:\debug\epson_test.log"
Write-Host "Installing silently via $($SetupPath.FullName)..." -ForegroundColor Cyan
$InstallArgs = @("/VERYSILENT", "/NORESTART", "/SUPPRESSMSGBOXES", "/LOG="$env:TEMP\EPSON_Install.log"")
Start-Process -FilePath $SetupPath.FullName -ArgumentList $InstallArgs -Wait -NoNewWindow epskitx64exe silent install parameters install
epskitx64.exe /s
If help output is absent, try these common switches from an elevated command prompt (pick one at a time and test in a VM): Write-Host "Installing silently via $($SetupPath
If EPSKitX64.exe refuses to extract via /a or /extract, use 7-Zip: If help output is absent, try these common
"C:\Program Files\7-Zip\7z.exe" x EPSKitX64.exe -oC:\ExtractedEpson
7-Zip treats many self-extracting EXEs as ZIP archives. Inside you will often see files like data1.cab, data1.hdr, and setup.msi.
ePSXe typically uses Inno Setup as its installation wrapper. This is a standard industry tool, meaning it accepts a specific set of command-line parameters that are consistent across thousands of different applications. Even if the file is named epsxe200.exe, epsxe_x64.exe, or epsxe_full.exe, the underlying engine usually remains the same.
