I made a folder in the directory packs/langpacks/w10/x64/, and named it en-GB. I placed the .cab in that folder, yet MSMG still states that it couldn't find any. I just can't figure out why.
Have you tried putting the cab file in the updates section? Then you tell MSMG toolkit to install updates.
Well this is RS4. But, I can do the same with RS3. Actually I have one that is 16299.15 that is way way more heavily modded than the screenshot I showed. I am downloading from Mega now. I will install in a VM tomorrow, and we will see how it updates!
MSMG often takes a break from this little project in favor of schoolwork, work, and family since they are his top priority. His toolkit is something he only does in his free time. Today is the night before Christmas and I can easily assume he is spending his time with family. New Years is also only 8 days away too. No one should expect MSMG until after the holiday. Merry Christmas to you all and to you all a good night
