Error Containing the Text /SecondRun and /FirstRunThreadld: (Installing F/X CAD)

Issue

While attempting to install F/X CAD, you saw an error message that includes the following text:

/SecondRun and /FirstRunThreadld:

Cause

An issue with the temp directory on your computer is interfering with the installation.

Solution

1. Download the latest trial version of AutoCAD from the Autodesk website.

2. Attempt to install the trial version of AutoCAD. If you are unable to install the AutoCAD trial, you are experiencing a Windows issue with the temp directory.

You have two options for resolving this issue:

Option 1:

Log in to a different Windows account and install F/X CAD.

Option 2:

The following steps will show you how to change the location of the Windows temp folder temporarily.

1. Open Windows Explorer, and create a new folder directly on your C: drive.

2. Give the new folder the name Test.

3. Open your Control Panel, and select the System option.

Depending on your version of Windows, this option may be named System and Security. If so, select this option, then select the System option on the next page.

4. In the System dialog box, select the Advanced system settings option in the left panel.

The System Properties dialog box will open. Select the Advanced tab.

5. Click the Environmental Variables button.

6. Double-click the TEMP variable.

Click OK.

11. Change the Variable value to C:/Test (the directory name of the folder you created in Step 2 above.

Click OK.

12. Now try to install F/X CAD again.
