F/X CAD Cannot Function Without Land F/X Installed Correctly

One common cause of this issue is that your LandFX folder is located on a network drive, but that drive is not accessible.

In fact, the drive letter may even appear to be accessible, but it could have a red X next to it, indicating that Windows has not re-established the connection yet.

 

 

In this case:

 

1. Double-click the name of your network drive, as pictured to the right.

2. If you're able to navigate to the LandFX folder on your network drive, verify that it contains a file named LandFX.vlx.

 

 

3. If your LandFX folder does contain a file named LandFX.vlx, try restarting F/X CAD.

 

F/X CAD should now start properly.

If F/X CAD does not start correctly, follow our steps to verify that the Support File Search Path is correct.

If the error seems to pop up often because of an inaccessible network drive, it's time to look at your network drive and see about having it re-mapped on startup in a more reliable way, such as a logon script that fires the NET USE command.

We've had an ongoing issue with clients sometimes getting the F/X CAD cannot function error upon rebooting. This issue typically occurs because the user's office has a mapped drive that is not connecting correctly during the reboot, which in turn causes problems between F/X CAD and Land F/X.

To resolve this issue, use the link below to download our Disconnecting Drive Fix tool. Download the tool to a location where you can find it easily, such as your desktop or Downloads folder.

Go to the location where you downloaded the file linked above.

 

Locate and double-click the file DisconnectingDriveFix (or DisconnectingDriveFix.exe).

Use the menu to select the letter assigned to the mapped drive that keeps disconnecting when you reboot. Then click Next.

Disconnecting Drive Already Configured

 

If you see this message, it means our Disconnect tool has already been used to set up a letter drive in your office. Click Yes to add another drive to the list, or click No to replace the previous drive with the drive you've just selected.

You'll see a message that the selected drive will now be reconnected on each reboot.

 

You should now be able to reboot your computer and open CAD without seeing the error.

In some cases, we've seen this issue occur when the Adobe PDF utility is attempting to load, yet the LandFX.vlx code has not loaded yet. As a result, this message will pop up a number of times when you start F/X CAD. (But then once LandFX.vlx loads, everything continues without issue.)

If you're getting this error each time you open CAD, you can remove the Adobe PDF utility from your AutoCAD installation:

1. Navigate to the folder C:\Program Files\Adobe\Acrobat 7.0\PDFMaker\AutoCAD\(your year version of AutoCAD).

2. Delete the following files from that folder:

• AcrobatAcadIC.arx
• AcrobatAcadIC.dbx
• PDFMAcad.arx

A less-common cause is that the LandFX.vlx file is actually damaged or missing.

This can occur for three possible reasons:

Reason #1: You recently updated, and it either corrupted or deleted the file LandFX.vlx.

 

In this case, your LandFX folder should contain a LandFX.vlx.bak file that you can restore by reverting to a previous version after an update.

 

Odds are, the issue won't occur again the next time you update.

Reason #2: LandFX.vlx can also become corrupted or go missing if your LandFX folder was accidentally moved or erased, or the Land F/X Server component has been uninstalled.

In the case that you just installed Land F/X and are receiving this error, the cause is undoubtedly that you accidentally skipped the step of actually installing Land F/X in the first place.

For example, to install Land F/X while installing F/X CAD, you need to select the option I do not already have Land F/X.

If you didn't select this option when installing, Land F/X is likely not installed on your computer. If this is the case, you'll need to install Land F/X.

Reason #3: You applied the update while one of the Properties window was open, and you have F/X CAD 2017 or earlier.

In this case, you'll have seen the F/X CAD cannot function error right after opening F/X CAD. If so, and you have version 2017 or older, you can resolve the issue by either:

• Running the update using the Update flyout button from the F/X Admin ribbon (pictured to the right), and then upgrading to a newer version of F/X CAD, or ...

• ... following our steps to uninstall and reinstall F/X CAD, making sure to use the latest installer for your version of F/X CAD.

Another utility or CAD add-on may be running before the LandFX.vlx is loaded and, as a result, temporarily preventing it from loading. To check for and address this issue:

1. Press the F2 key.

2. The AutoCAD Command line will expand, showing the command history. Check the list of commands to see which utilities have loaded, and in which order.

Do you see an entry about Land F/X loading? Are there entries before it? If so, please take a screenshot of your command history and send it to us in a technical support ticket. This screenshot can help us troubleshoot the problem.

3. In the meantime, you can load the LandFX.vlx file manually by copying and pasting the following text – including the parentheses – in the Command line:

(load “landfx.vlx”)

Press Enter after pasting the text into the Command line. The LandFX.vlx file will load, and you can continue to work while we attempt to troubleshoot the issue from your support ticket.
