Cause

We've been seeing this issue from time to time with AutoCAD and AutoCAD Civil 3D 2017 installations. A quick fix from AutoCAD Service Pack 1 will take care of the problem.

 

Solution

1. You might see the error message pictured to the left as well.

 

Click No to close the error message.

 

 

 

2. Follow this link to Autodesk's AutoCAD 2017 Service Pack 1 page.

 

 

 

3. Scroll down on the Service Pack 1 page until you see the download options pictured to the left.

 

Click the correct AutoCAD 2017 SP1 version for your computer (64-bit or 32-bit).

This step will actually require you to download and install two separate files When you click the download link, your browser will either prompt you to download multiple files or open a secondary pop-up window, which may be easily overlooked or hiding behind the browser. (What you see will depend on your browser settings.) You may need to poke around a bit to find them. See the images below for examples.

 

Using Google Chrome? You should see a message that the Autodesk site wants you to download multiple files. Click Allow.

Using Mozilla Firefox? You'll have two download windows, which may or may not be hidden behind the browser window. Click Save File in each message.

 

 

4. The following two files will download to your computer:

  • AutoCAD_2017_SP1_Part_2_Genuine
  • AutoCAD_2017_SP1_64bit

 

Take note of the file names, and save the files in a location where you can find them easily.

 

 

 

5. Run each of the files you downloaded. Allow a few minutes for the Service Pack to install and repair your installation.

 

 

 

6. You'll see a message that the service pack was installed successfully. Click OK.

 

 

 

You should now be able to use AutoCAD 2017 or AutoCAD Civil 3D 2017 without getting the error.
