在 Windows 7 上安装 Visual Studio 2008 和 SQL Server 2008 后，使用 SQL Management Studio 连接到服务器时出现以下错误:

After installing Visual Studio 2008 and SQL Server 2008 on Windows 7, I get the following error when connecting to a server with SQL Management Studio:

无法将类型为System.__ComObject"的 COM 对象转换为接口输入Microsoft.VisualStudio.OLE.Interop.IServiceProvider".这个操作失败，因为 COM 组件上的 QueryInterface 调用对于 IID '{6D5140C1-7436-11CE-8034-00AA006009FA}' 的接口由于以下错误而失败:不支持此类接口(来自 HRESULT 的异常:0x80004002 (E_NOINTERFACE)).(Microsoft.VisualStudio.OLE.Interop)

我看过一些博客文章建议重新注册 actprxy.dll，但这没有效果.有人知道如何解决这个问题吗?

I've seen blog postings recommending reregistering actprxy.dll, but this has no effect. Anyone know how to resolve this issue?

推荐答案

actprxy.dll 对我也不起作用.我找到了一个有效的解决方案 这里

actprxy.dll also didn't work for me. I found a solution that worked here

regsvr32 "C:\Program Files\Internet Explorer\ieproxy.dll"

regsvr32 "C:\Program Files\Internet Explorer\ieproxy.dll"

如果您运行的是 64 位 Windows，请尝试以下操作:

if you are running 64 bit windows, try this:

regsvr32 "C:\Program Files (x86)\Internet Explorer\ieproxy.dll"

regsvr32 "C:\Program Files (x86)\Internet Explorer\ieproxy.dll"
