最近由于由于给客户端下派office补丁导致大量客户计算机office组件无法正常使用，弹出某个文件定位的一个提示窗口，造成该问题的主要原因是由于office后续的核心组件或者关键组件更新时需要使用到源安装路径或者源安装光盘或者源安装缓存（MSOcache）。如果源路径不存在或者缓存丢失，就造成上述现象。
如何避免上述问题或者发生之后如何解决？
1.安装完office后，再最后完成的那一页不要选择删除“安装缓存”，安装缓存会存放在剩余空间最大的分区中，命名为MSOcache（隐藏文件）。如果保存了安装缓存将不会造成上述问题。
2.如果公司的客户端全部是做的ghost镜像并且没有保留缓存，那就只有使用组策略下派脚本来批量解决问题了。
解决思路：修改注册表中的office缓存文件定位路径。
office注册表路径：
HKEY_CLASSES_ROOT\Installer\Products\*
其中*为一个字符串值，例如
4080110900063D11C8EF10054038389C或9040110900063D11C8EF10054038389C
复制以下代码为OfficeSource.vbs，然后通过组策略下发。
