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 ‘C*:\Users\\\\AppData\Local\Microsoft\Windows* or *C:\Users\\\\AppData\Local\Temp’*. Make sure that the hidden files and folders are shown in Windows. Open Windows Explorer and folder ‘C*:\Users\\\\AppData\Local\Microsoft\Windows* or *C:\Users\\\\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). 5.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://manual-1-3.karamba3d.com/chinese_1_3_3/troubleshooting/4.3.-miscellaneous-problems/4.3.1-installation-issues.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
