今天安装分析扩展，死活都安装不上去，提示如下错误
在网上找了半天
If you have SQL Server 2008 Analysis Services installed and you are installing the analysis extensions, you might receive an error that says you must install SQL Server 2005 Analysis Services with Service Pack 2. This error message indicates that there is an Analysis Services 2005 version of the Microsoft.AnalysisServices.dll file in the Global Assembly Cache. Microsoft Dynamics AX does not support running Analysis Services 2005 and Analysis Services 2008 on the same computer.
To resolve this issue, uninstall the Microsoft.AnalysisServices.dll file that has a version number of 9.0 from the Global Assembly Cache (typically located at C:\Windows\assembly).
大概的意思就是说系统里有两个版本的 Microsoft.AnalysisServices.dll，但是AX不支持同时存在Analysis Services 2005 和 Analysis Services 2008在同一台电脑上，按照他说的意思去做，又得到如下错误
死活都卸载不掉，求解！！！！
