How can i fix this? this is only problem i have run into. Thanks Brendon Quote
fraganator Posted March 28, 2022 Posted March 28, 2022 Hi Brendon, Can you open and unzip any of the CD rom zip files with 7-zip, outside of LaunchBox? If you have 7-zip installed, right-click on the CD rom zip file in File Explorer and select Test archive: If the test passes ok, does the emulator have the Extract ROM archives before running option checked (under Tools -> Manage -> Emulators, then double-click the emulator)? I assume it has, otherwise 7-zip wouldn't be called, but it's worth checking. To see why 7-zip is throwing an error, first enable LaunchBox's debug logging (under Tools -> Options -> General -> Debugging). After enabling it, close and open LaunchBox, then try run one of the CD based games to generate the 7-zip error. Once you see the error, open File Explorer and navigate to <LaunchBox>\Logs and find the latest log file. Open it and search for SevenZip.Extract Log. You might see something like this listed below that line. 2022-03-28 01:43:34 PM SevenZip.Extract Log: 7-Zip 21.07 (x64) : Copyright (c) 1999-2021 Igor Pavlov : 2021-12-26 Scanning the drive for archives: 0M Scan D:\Emulation\ROMs\Sony - PlayStation\ 1 file, 84175728 bytes (81 MiB) Extracting archive: D:\Emulation\ROMs\Sony - PlayStation\Doom (USA).zip 9% Open ERROR: D:\Emulation\ROMs\Sony - PlayStation\Doom (USA).zip D:\Emulation\ROMs\Sony - PlayStation\Doom (USA).zip Open ERROR: Cannot open the file as [zip] archive ERRORS: Is not archive 9% Can't open as archive: 1 Files: 0 Size: 0 Compressed: 0 That should give you a hint as to what has happened. Please post the log file here if you need some help parsing the log. Are you using any launchers or other plugins, or is a pretty vanilla LaunchBox / RetroArch setup? Quote
