Multiple Versions Installed
Windows only
When I install a new version of Beyond Compare, what happens to my old version?
Each major version of Beyond Compare for Windows will install separately on your computer. This means that if you have version 4 installed, and you install version 5, the new installation will not overwrite any of your version 4 files or settings.
If there is any concern about corrupting older versions when installing newer versions, you can choose to create a portable installation.
