できました。しかし、Archive Fileが正常でないといわれました。。。
Archive File Not Found!
The archive file name above must be the exact name of the archive file placed in the deployment path (character for character). If the file does not have the same name then rename it to the name above.
When downloading the package files make sure both files are from the same package line in the packages view. The archive file also must be completely downloaded to the server before trying to run step 1. The following zip files were found at the deployment path:
archive.zip
英語わかりません・・・ファイルの上げる場所が違うのでしょうか・・?
