# 4.1.1: 安装问题

## 重新安装Crasshopper后导致无法正常运行

重新安装Grasshopper时可能会导致无意中卸载Karamba3D程序包的某些文件。请尝试重新安装Karamba3D。

## 无法显示安装的运算器或显示未安装任何运算器

* 在运行安装前，请确认已取消了阻止Karamba3D安装的（\* .msi）文件。 请在（Explorer）资源管理器中右键单击该文件后查看其**“Properties（属性)”**。如果文件已被阻止，则在“Properties（属性）”窗口底部会有一个**“Unblock（取消阻止）”**文件的选项。

* 确认以管理员身份安装Karamba3D。
* 检查Karamba3D的安装目录。它应当位于Rhino的Plugins（安装插件）文件夹中。通常是*C:\Program Files\Rhino 6\Plug-ins*或*C:\Program Files\Rhinoceros 5.0 (64-bit)\Plug-ins*，但也可以是*C:Program Files\Rhinoceros 5 (64-bit)\Plug-ins*。确保文件夹相关联，否则Karamba3D将不会出现在Grasshopper中。
* 如果您的计算机上有多个Rhino版本，请确保已将Karamba3D安装到正确的版本。 Karamba3D可并行安装至“Rhinoceros 5（64-bit）”、“Rhino 6”和“Rhino 7”。在这种情况下，已安装应用程序列表中将显示存在三个“Karamba3D”条目。
* 用户也可以导航至RhinoPlugins（安装插件）文件夹（如*C:\Program Files\Rhino 6\Plug-ins* for example），并将**Karamba.gha**文件拖放到Grasshopper的画布中。

When installing Karamba3D on Windows 8, and an error message pops up stating *‘There is a problem with this Windows Installer Package. A DLL required for this install to complete could not run. Contact your support personnel or package vendor.’* do the following:

1. Make sure that you installed a Karamba3D version with the correct bitness: Karamba3D (64bit) can be used together with Rhinoceros 5 (64bit); Karamba3D (32bit) with Rhinoceros 5. Be aware of the fact that both versions of Rhino get installed.
2. Check to see if the installation file downloaded contains the \*.msi extension. Sometimes Windows automatically adds  an \*.exe extensions to \*.msi files.
3. Make sure that Windows is up to date.
4. Change the permissions to full access to ‘&#x43;*:\Users\\\<username>\AppData\Local\Microsoft\Windows* or *C:\Users\\\<username>\AppData\Local\Temp’*. Make sure that the hidden files and folders are shown in Windows. Open Windows Explorer and folder ‘&#x43;*:\Users\\\<username>\AppData\Local\Microsoft\Windows* or *C:\Users\\\<username>\AppData\Local\Temp’*. Right click on the folder, the *Local Properties* pop up window will appear. Select the tab **Security**. Click **Edit,**  the **Permissions** *for **Local*** pop up window will open. On **Group** or *\\***user names**, select the desired user. Ensure that the ***Allow** \_check box for **Full control** is activated, else activate it. On the **Permissions** \_for Local* pop up window, click **OK** (if no changes were made) or **Apply** (if changes were made). On the **Local Properties** pop up window, click **OK** (if no changes were made) or **Apply** (if changes were made).
