There is now a new version replacing 1.84 of Real Alternative, version 1.90. If you want the normal Real Alternative 1.90 and not the MSI installer version that is below, you can find it at Codec Guide.
MSI Installer Downloads
Details on the build process can be found here at my first Real Alternative 1.75 MSI Install. As always you should actively virus scan these files if you don’t trust them.
