the 7z file has been created with a new lzma2 compression method, so please use either 7-zip 9.17 or winrar 3.93 which are the latest versions, as they will successfully extract the compressed file. PS - just tested the compressed file and extracted the contents with no issues.
no problem, and i intend to keep my ulz's alive, and i'm going to add 6 language packs to my win7 rtm ul's for the next update. Languages: English, French, German, Italian, Japanese, and Spanish.
No problem, i'm glad to help. I've even prepared 2 new UL's for SP2 Beta which MS will release later this year, and i've even created another 2 new UL's for Windows 8 Beta for whenever MS releases that too, my guess would be approx. July/August, but who's to say really. Are you going to update your lists soon?
