PRB: "VC Package Not Available or Not Registered" Error Message
适用于
This article was previously published under Q320427
SYMPTOMSWhen you create a WinForms application, you may receive the following error message:
"VC Package not available or not registered"
This behavior can occur even after what appears to be a successful installation.
CAUSEThis behavior seems to occur because the Windows Installer does not register TLBs and DLLs if the installer finds that these items already exist. In most cases, a previous version of Visual Studio .NET causes this behavior, even if the previous installation was under a different operating system.
RESOLUTIONTo resolve the problem, run the Visual Studio .NET repair. A repair is more effective for fixing this issue because the repair process forces registration of items that are not re-registered during an install.
To run the repair, follow these steps:
On the Start menu, point to Settings, click Control Panel, and then click Add/Remove Programs.
On the list of installed programs, click Visual Studio .NET, and then click Change.
Click the second item in the 1 2 3 Visual Studio Setup dialog box.
Click Repair/Re-install, and then follow the onscreen instructions.

我年初遇到过这个问题,就是安装了一个VS.NET的插件后又将它卸载了,vs.net就无法再添加webform或类库,说无法运行某个wiz向导,记得好象是通过运行
regsvr32 <VisualStudioInstallDir>\vc7\vcpackages\csproj.dll
这个命令解决的,你可以试试,或者看一下这个帖子:

不会吧
.net的类库不需要注册就能用的
一般把它放到bin文件夹里
使用的时候引入它的命名空间就可以使用了

那你的类库是否是托管的?
非托管的类库是不能直接引用的
