Win32 is what you are running when you boot and run programs from a normal Windows environment (eg, not DOS). If you got that message when double clicking the exe within Windows, it might mean the program is corrupt or that you do not have one of the necessary dll's to run the program.

You can fix some compatibility issues that are due to the changes made between Windows operating system versions. These issues can include User Account Control (UAC) restrictions.
Important
The Application Compatibility Toolkit (ACT) installs a 32-bit and a 64-bit version of the Compatibility Administrator. You must use the 32-bit version for 32-bit applications and the 64-bit version to work for 64-bit applications. You will receive an error message if you try to use the wrong version.
If you start the Compatibility Administrator as an Administrator (with elevated privileges), all repaired applications can run successfully; however, virtualization and redirection might not occur as expected. To verify that a compatibility fix addresses an issue, you must test the repaired application by running it under the destination user account.
Compatibility Fixes
The following table lists the known compatibility fixes for all Windows operating systems that have been released from Windows Vista through Windows 10. The fixes are listed in alphabetical order.
Compatibility Modes![]()
The following table lists the known compatibility modes.
Contents.Basic ConceptsDOSBox is an emulator that recreates a MS-DOS compatible environment (complete with Sound, Input, Graphics and even basic networking). This environment is complete enough to run many classic MS-DOS games completely unmodified. In order to utilize all of DOSBox's features you need to first understand some basic concepts about the MS-DOS environment. (Modems/Networking)InstallationThe first step is to install DOSBox.
This guide will use the Windows 32-bit version which is available for. Download the for your operating system. If you are a Windows user, get the Win32 installer.After downloading, install DOSBox to any directory.
Also, make a folder to put all your old games in. I put DOSBox in C:DOSBox, and my old games directory is C:OLDGAMES. I put a game in my OLDGAMES directory, TESTDRIV, which is, an old racing game. Your directories should look like this:Running a gameNow, the hardest part, getting games to run. First, run dosbox.exe in your DOSBox folder. Remember that OLDGAMES directory you created in Step 1?
You have to basically set that as new directory just for DOSBox. Essentially, it's going to become the drive of DOSBox. So, type:Z: MOUNT C C:OLDGAMESDrive C mounted as local directory C:OLDGAMESTo dissect the above:.: Tells the program to a directory. C: Tells the program what you want your new drive to be called (leaving it as C: is fine). C:OLDGAMES: This is the directory I want to set as the new drive for DOSBox, because all my games are in it. If you created a different directory, write in the directory you created.(Note: If you want to a CD-ROM instead of a folder, type this: Z: MOUNT D D: -t cdromMSCDEX installed.Drive D is mounted as CDRom D:(Note: 'cdrom' is case sensitive and must be lowercase!)In this example, D: -T cdrom tells DOSBox that my D: drive is a CD-ROM drive, and the first D, tells DOSBox what my new drive name should be called.
If you are running your game off a CD-ROM then make sure to use D: in place of C: in the following examples. You can find instructions on how to other devices, such as floppy drives, in the section).After you've done this, you will be prompted with a. Now, just write what you wanted to call your new DOSBox drive, which as I said above, we called C. To navigate to that newly mounted drive just type in:Z: C:C:Hopefully, you're all set! Now, it's time to run the game.
Previously I had mentioned a game called TESTDRIV in my OLDGAMES folder. I now want DOSBox to go to that folder. So type in:C: CD TESTDRIVC:TESTDRIVThat's it! Stands for 'Change Directory', so you've changed the directory to TESTDRIV. You can find instructions on how to use the command, in the section of the article.One more step, running the game! Most games have an EXE file in their directory that you can run.
However, some might require a BAT file, or COM file (common in demos and really old games). Most of the time, the file is in the root folder. Please consult the documentation of your game for which file is needed to start the game. In the case of, it's TDCGA.EXE.
So now, I just type this:C:TESTDRIV TDCGA.EXEThat's it! Here's a picture of all of the commands I've written about in Step 2:Alternate methods for running a gameThe steps described above are closely aligned with how DOS Based operating systems behave natively. However modern operating system allow for more user friendly (although less authentic) ways of playing your favorite games.
If the steps above seem tedious or confusing you can try some of these other guides. In most cases these guides will still require you to setup a working DOSBox environment.NOTE: If you have problems with launching the game, unrecognizable errors being spit out, saving settings, or having the game drop out while running it, one thing to try is to make sure all the files are not set to Read Only. In Windows, select the folder of the game, right click and hit properties, uncheck Read Only if it is checked, and apply to all sub folders.If you have other errors, please search the first before posting a question.PerformanceYay, you've gotten your game to run! But maybe you're experiencing slowdown? How do you fix this? With the following commands:CTRL+F7 = Decreases frameskipCTRL+F8 = Increases FrameskipCTRL+F11 = Slows down the gameCTRL+F12 = Speeds up the gamePress CTRL+ALT+DEL to open the Task Manager, and click the Performance tab. Start by pressing CTRL+F12 until your CPU Usage level begins to go above 95%.
After that, if you still need a performance boost, hit CTRL+F8 to have DOSBox not render some frames. The console window will display all of the changes you've made, and the top of the game window will display the current settings. Adjust these settings as needed until your game goes smoothly.
Please keep in mind that not all games will run smoothly on DOSBox.Other Useful features Quick Start for WindowsWindows users have an option of dragging the EXE of their DOS game onto the DOSBox program (or shorcut pointing to the DOSBox program). This will automatically start the game.
If this doesn't work, then I would recommend reading the rest of this article.Automatically Mounting Your DOS Games folderYou can save yourself some time by having DOSBox automatically your folders and change the drive to C. In original DOS based operating systems a file called contained any commands that the user wanted executed every time the computer booted up. This functionality is simulated by the section of the file.For DOSBox versions older than 0.73 browse into program installation folder and open the file in any text editor. For version 0.73 go to Start Menu and click on 'Configuration' and then 'Edit Configuration'. Then scroll down to the very end, and add these lines:MOUNT C C:OLDGAMESC:Now those commands will be executed automatically when starting!
If you're having trouble with that, make sure it looks like this (look at the bottom):Full ScreenJust press ALT+ENTER to go into and out of full screen.Alternatively, you can open the file as mentioned above and change 'fullscreen=false' to 'fullscreen=true'. DOSBox will then run in full screen mode when you open it.
