Julia Child: Home Cooking doesn't run, Interrupt 0D error

[Gaurav-Original-ClassicShellTester]

Running the latest build of OTVDM as of 28th July, 2020.

The app Julia Child: Home Cooking with Master Chefs (download and mount image from here: https://www.legendsworld.net/site/download.php?mirror=13394) doesn't run correctly and continuously gives "Interrupt 0D" errors.

Here's a trace: trace.zip

The Setup for this app hangs so it has to be manually installed. Microsoft supplies a batch file on its CD to manually install it. From cmd prompt at E:\ where E: is CD drive letter with the Julia Child CD mounted, run this command:

E:\AAMSSTP\MANUAL\PSS.BAT InstallDirectory WindowsDirectory e.g. E:\AAMSSTP\MANUAL\PSS.BAT C:\MSJulia C:\otvdm\Windows

Then edit C:\otvdm\Windows\MSJULIA.INI to point to correct install location and CD drive letter.

The program starts but then gives continuous errors as mouse is hovered over the bottom buttons. Trace is attached.

This problem is caused by https://github.com/otya128/winevdm/commit/8ec3aff00f0e734f938fcae97df4ac848cb20a46 where the usage count is incremented twice. The program calls FreeResource then GlobalFree even if the free fails. Without knowing what the change fixes I don't want to mess with it.

Oh OK. So it looks like the same Interrupt 0D error occurs in the Windows Entertainment Pack game called Klotski, Microsoft Oceans, Microsoft Automap Streets (1995 edition), Ultimate Frank Lloyd Wright, StarOffice 3.1, Macromedia Action 3, Corel Suite 5, Oxford SuperLex, TexTMaker, Civilization II . So it seems a lot of apps are affected by General Protection faults. (https://www.google.com/search?q=%22Interrupt+0D%22+site%3Agithub.com%2Fotya128%2Fwinevdm%2Fissues)

GP faults can happen for a very wide variety of reasons and most of those have been fixed already.

I see. Thanks. I hope the devs know what that change fixes.

This is a commit that fixed a setup program crashing, but it worked after reverting.

Even after this revert/commit, the error is the same: https://i.imgur.com/kW9vZEL.png

Yes it's fixed. With today's fix, this title is also added to the list of apps that work. I have made a list by testing the following first-party/Microsoft apps. Some are pure 16-bit or hybrid 32-bit & 16-bit titles, or where installer components are 16-bit and as of the latest build, all of these work mostly fine. Some old 16-bit MS Office apps also work though not all (not in this list). Excuse me if some apps are pure 32-bit in the list in which case OTVDM does not play any role.

Older 16-bit or hybrid Microsoft Bookshelf (94, 95, 1996-97, 98) and Microsoft Encarta (94, 95, 96, 96 World Atlas, 98) titles also run fine.

Thank you very much. Now I will test more complex 16-bit games.
