checking the update后报错的，其实不用装ubisoftgamelauncherinstaller.exe
只需将以下内容复制到文本文档 然后保存为reg文件,导入注册表项目即可：
windows registry editor version 5.00
[hkey_local_machinesoftwareubisoftassassin’s creed revelations]
"installdir"="."
"language"="english"
[hkey_local_machinesoftwareubisoftassassin’s creed revelationsgameupdate]
"execpath"=".acrsp.exe"
"info"="37a28dced5284d04a1bf8c32a644fb54"
"installdir"="."
"language"="us"
[hkey_local_machinesoftwareubisoftlauncher]
"version"="0421"
"installdir"=".orbit"
