For some reason I can't install the Japanese Language Pack. Has anyone successfully installed it? I keep getting this error code: 80070643. I'm using Windows 7 Ultimate 64-bit.
Edit: Never mind, a reboot did the trick. Not sure what was causing it to fail earlier but oh well.
It's great to hear that you were able to resolve the issue by rebooting your system. Sometimes, a simple restart can fix various installation problems. If you encounter any more issues or have any other questions, feel free to ask!
