ProjectPilot does not open, displaying the following error message:
“Unable to create ProjectPilot control. Is the registry correct?” What can I do?


Step 1
Start the Services application -> Service -> Windows Explorer -> CAD program folder.
Open the "PRG" folder.
Find the following file: "NemProjectPilot10.exe"
Right-click this file -> select "Run as administrator" on the shortcut menu.
Try to start ProjectPilot from Allplan.
If ProjectPilot does still not start, go to step 2.

Step 2
Check whether updating the software of the virus scanner solves the problem.
If it doesn't, configure the real-time scanner of the virus scanner so that
it no longer scans the program folder and data folder of Allplan.
Start the Services application: Make a note of the following paths displayed in the Services application window:
Program folder
General program data
Central file storage folder
Define these folders as exemptions in your virus scanner.
If ProjectPilot does still not start, go to step 3.

Step 3
This problem is often caused by an "external path" that no longer exists. When you start ProjectPilot,
the program tries to access the "external path", which is stored in the Windows Registry.
If this path no longer exists, you will see the above error message.

To correct this error, do the following:

  • Start the Services application -> Service -> Windows Explorer -> My own CAD documents (USR).
  • Find the "extern.cfg"file in the user folder and delete this file.

If ProjectPilot does still not start, go to step 4.

Step 4 (Windows 10 or later)
Open the PRG folder of Allplan in Windows Explorer (for example, C:\Programs\Allplan\Allplan 2018\prg).
Start the Services application. The folder you selected for the Allplan program during installation is displayed directly in the Services application window.
Right-click the "NemProjectPilot10.exe" file in the Allplan program folder. A shortcut menu opens. Click “Properties”.
Open the “Compatibility” tab and select the “Disable fullscreen optimizations” option. After having selected this check box, click “Apply” at bottom right.

If several users with different user profiles use Allplan on this computer, click the “Change settings for all users” button first. Then, disable fullscreen optimizations as described above.

If ProjectPilot does still not start, go to step 5.

Step 5
Fix Allplan.
To find out how, go to
After installation, try to start ProjectPilot.
If ProjectPilot does still not start, go to step 6.

Step 6
If ProjectPilot does still not start, the most likely cause of this problem is security software such as the virus scanner.
Remove, that is, uninstall the local virus scanner with all its services from the Allplan computer having these problems.
After this, ProjectPilot will start.
To reinstall the security software or virus scanner with its appropriate settings,
contact the support service of the software provider. uses cookies  -  More information
