System Requirements:
- 32-bit: Windows XP + SP3 or newer.
- 64-bit: Windows Vista or newer.
- 20 MB available hard disk space.
Packaging Choices:
DiffMerge is distributed on Windows as a standard Microsoft Installer (MSI) package and as a ZIP archive. There are now separate versions of these packages for 32-bit and 64-bit systems.
The 64-bit package includes both the 64- and 32-bit versions of the Windows Explorer Shell Extension so it should work with both Windows Explorer (64-bit) and various third-party shell replacements (usually 32-bit).
Installing from the MSI Package:
The 32-bit MSI package can only be installed on a 32-bit version of Windows. The 64-bit MSI package can only be installed on a 64-bit version of Windows.
The preferred method of installing DiffMerge is to use the MSI package. To do so, simply click on the file and follow the on-screen instructions.
This will install the application in Program Files, install the Windows Explorer/Shell Integration Extension, create menu items in the Start Menu, and create a Desktop Shortcut.
To uninstall DiffMerge either click the MSI file again or use the Add/Remove Programs (aka Programs and Features) Control Panel and follow the on-screen instructions.
Installing from the ZIP Archive:
If for some reason you cannot use the MSI package or simply prefer to use the ZIP file,
you may simply unzip the ZIP file somewhere on your system. sgdm.exe and the related
files will all be in this directory.
Use the 32-bit ZIP archive on 32-bit versions of Windows. You can use the 32-bit or 64-bit ZIP archive on 64-bit versions of Windows.
