Description

MSI from Saturn PCB Design Toolkit installer https://www.saturnpcb.com/pcb_toolkit.htm v7.02 uses Caphyon Advanced Installer (not the "W" version which uses GkSetup)

Wine Staging 1.9.23 Xubuntu Linux 14.04 x86_64 Net Framework 4.0 installed by winetricks 20161005 (env WINEARCH=win32 winetricks -q dotnet40)

I encountered the problem when trying to diagnose a crash with the Toolkit installer caused by Wine bug #34989. The MSI is left behind:

$HOME/$WINEPREFIX/drive_c/users/$USER/Application Data/Saturn PCB Design, Inc/Saturn PCB Toolkit V7.02 7.02/install/Saturn PCB Design, Inc. - PCB Toolkit.msi

It loads and shows the contents but fails to extract anything. It works properly with other MSI files:

System.Exception: Error copying file …install\disk1.cab to …\disk1.cab LessIO.Strategies.Win32.Win32FileSystemStrategyCopy

See screenshot.

Contributor guide

Research direction
Investigate the error copying file from cab during extraction. Check if the issue is related to the cabinet format used by Advanced Installer on Wine. Look at the LessIO copy strategy and compare with working MSI files. Possibly reproduce with a sample MSI from that installer.
