Error: "Base.dcl" Can't Find File /Error Loading Dialog Control File / Semantic Error(s) in DCL File / Error in Dialog File (Installing Land F/X or Opening AutoCAD or F/X CAD)

Cause

This error can result from the accidental deletion of a particular entry in your Support File Search Path. It can also result from a damaged AutoCAD Roaming Support folder that needs to be re-created.

Solution

To address this error, open the AutoCAD Options dialog box:

Manage ribbon, Options button

 

 

 

type Options in the Command line

 

 

 

 

right-click in the Command line and select Options from the menu

Tools pull-down menu

The Options dialog box will open.

Select the Files tab, then expand the Support File Search Path item by clicking the plus (+) sign next to it.

In the expanded Support File Search Path folder, the top entry should be: C:\Users\*username\AppData\Roaming\Autodesk\AutoCAD 20xx\RXX.X\enu\support

(where *username is your Windows username, 20xx is your version of AutoCAD, and RXX.X is the name of the single folder in your AutoCAD version folder)

If the top entry in the Support File Search Path is NOT the path shown above, you'll need to complete the following steps to correct the issue.

1. Ensure that your hidden files and folders are turned on.

2. Once you're sure that your Hidden and System files are turned on, click Add. Then click Browse.

3. The Browse for Folder dialog box will open.

 

 

Scroll down and expand the entry for This PC (if you have Windows 10) or Computer (if you have Windows 7).

 

 

Then expand the Local Disk (C:) entry.

 

 

 

 

4. Once you've expanded the Local Disk C: entry, expand the following entries:

• Users
• your username (example: Jason)
• AppData (Note: you won't see this folder unless you have your hidden files and folders enabled.)
• Roaming
• Autodesk
• AutoCAD 20xx (where 20xx is your version of AutoCAD or F/X CAD)
• Rxx.x (The exact name of this folder will vary depending on your version.)
• enu

 

 

 

 

Then highlight the folder Support and click OK.

 

 

 

 

This folder tree will be added to the Support File Search Path.

5. The Support File Search Path will now include the folder tree you added:

C:\Users\*username\roaming\autodesk\autocad 20xx\rxx.x\enu\support

Select this folder tree and click Move Up.

6. Continue to click Move Up until the folder tree is at the top of the list.

Then click OK to save the change.

7. Close and restart CAD. If you don't see an error message and you can use our software without further issue, you've resolved the problem.

Still getting an error, or is the software otherwise not functioning correctly? If so, move on to the next step.

8. Open the Options dialog box again, and look for the path you just added (C:\Users\*username\roaming\autodesk\autocad 20xx\rxx.x\enu\support) in the Support File Search Path.
