IsoBuster 5.0 Beta Released!

June 13, 2022

IsoBuster 5.0 Beta, a release candidate for IsoBuster 5.0, is ready !

This version involves a massive rewrite again to be able to support all the new features

From now on there will be two versions that can be used under the same license. A 32 bit version and a 64 bit version. Any modern system these days is 64 bit and that's the IsoBuster version you should be using as well. For legacy reasons however we will still maintain a 32 bit version as well, for as long as that is possible.

The 32 bit version supports Windows XP and higher (Windows XP (SP3), Vista, 7, 8, 10 and 11)

The 64 bit version supports Windows 7 and higher (Windows 7 (SP1), 8, 10 and 11)

Please Install and Run this Beta version ! If there are any issues, now is the moment to report them. Don't wait until the final is out, which will be soon. This 5.x Beta version still runs on a 4.x license key !

Let us know if you run into issues or have feedback
