我想安装ADOBE Acrobat professional. 在安装过程中， 出现以下MESSAGE：
Error 1303
The installer has insufficient privileges to access this directory: C:\Documents and settings \all users\Documents \Adobe PDF 7.0 The installation cannot continue. Log in as an administrator or contact your system administrator.
我就是administrator.
现在我应该怎样做？谢谢！
