Hello,
Neither the Windows 10 unzip tool nor the Ubuntu Linux archive manager
could open the zip file, but 7-Zip for Windows was able to recover a
single large tar file from the zip. After un-tarring, all the SDK files
were there!
You might want to take a look at your SDK builder, though. It is
frustrating that it is creating corrupted zip files that are not
accessible from the default unzip apps on both Windows and Linux!
Thanks,
