vista2xp --- Vista-to-XP application converter

What's this?

This software may be able to convert an app for Vista/7/10 to an XP app. I'm sorry if unable to do it.

Platforms: Windows XP/Vista/7/10

Download: https://katahiromz.web.fc2.com/vista2xp/en

How it works?

It modifies the IAT (Import Address Table) of EXE/DLL files.

  • If any Vista+ kernel32 functions, importing of kernel32.dll will be altered to v2xker32.dll.
  • If any Vista+ comctl32 functions, importing of comctl32.dll will be altered to v2xctl32.dll.
  • If any Vista+ user32 functions, importing of user32.dll will be altered to v2xu32.dll.
  • If any Vista+ ole32 functions, importing of ole32.dll will be altered to v2xol.dll.
  • If any Vista+ shell32 functions, importing of shell32.dll will be altered to v2xsh32.dll.
  • If any Vista+ msvcrt functions, importing of msvcrt.dll will be altered to v2xcrt.dll.

You can check the IAT by dumpbin /imports of Visual Studio Command Prompt.

How to use?

  1. Open vista2xp.exe program file. A dialog box will be open.
  2. Drop the EXE/DLL files to the dialog to be converted.
  3. Click the [Convert] button.
  4. Files will be converted. Some DLL files will be automatically added if necessary.
  5. If you want to revert, please use the files inside the Vista2XP-Backup folder that was created.

If you are lacking DirectX 10 support, take a look of this: https://km-software-directx-10.apponic.com/.
