OCR is missing

Just installed C-PEN Core and it does not start properly?

Is there a “OCR is missing ” error message?

The later versions of C-PEN Core uses a newer version of the OCR engine (Optical Character Recognition) and if a previous version of C-PEN Core has been installed and not properly removed – then the new OCR is not properly installed. If this happens, or the OCR is not properly installed for any other reason this message is shown.

To resolve it we need to make sure that any old OCR is removed and the new (which is included in the C-PEN Core installer) is installed.

These steps apply to Windows 10 but are pretty similar for earlier versions of Windows.

Go to Windows Settings\Apps and Features
Use the search list and search for OCR.
If C-Pen OCR Engine shows up – chose to uninstall it.
Now download and reinstall latest C-PEN Core version.

If required, please consult How to make a clean re-install article.

.NET is missing

Just installed C-PEN Core and it does not start properly?

Is there a “.NET missing” error message?

.NET is a Windows component used by C-PEN Core software, the Windows software to use with e.g. our TS1 models. In Windows 10, .NET 3.5 does not always come preinstalled which will cause this error. To resole it – .NET 3,5 needs to be installed manually.

The video below shows the step.

Open Control Panel
Go to Programs
Select Turn Windows components on or off.
Locate .NET 3.5 and make sure the check box is checked.
Click Apply/OK to install.

Now get back and try to restart C-PEN Core.

How to check which TS1 version is connected

There are two different versions of TS1. Originally there is TS1, which was discontinued during 2019 and replaced by TS1 (G2) – occasionally referred to as TS1 rev.2.

This is how to check which version is connected to your Windows PC:

How do I know if my TS1 is the original or the new G2 version?

Windows

Connect the TS1 to a USB port on your Windows PC

Start Device Manager (tap Windows button on the keyboard and start typing Device Manager and the option will show up)

Expand entry Cameras and check subentry. It will say either TS1 or TS1 rev2

Unable to load DLL ‘CPenCore.dll’

ERROR

Exception:
Unable to load DLL ‘CPenCore.dll’: The specified module could not be found. (Exception from HRESULT: 0x8007007E)

This and similar error(s) may be caused by missing dependencies. As a first step a clean reinstall is recommended to make sure all dependencies are correctly installed.

Troubleshoot TS1 (Windows)

If TS1 seems to connect properly to the computer (as seen in Device Manager) but still doesn’t connect to C-PEN Core app – please check Camera Privacy settings (applies to Windows 10).

It ay look slightly different in different versions of Win 10 but in general:

Camera access needs to be ON.
Apps needs to have access to camera. Especially the native Camera app and C-Pen Core desktop app.

Finding TS1 serial number

This is where you find the TS1 serial number.

How to install C-PEN Core on MAC

Download latest version of C-Pen Core: Knowledgebase\Downloads
Once downloaded, click to open the downloaded file.
Click Install C-Pen Core.app to start installation. If there’s a message about unidentified developer then check this.
In the top left corner, click on the Apple symbol –> System Preferences. Under section Other, click on C-Pen Core settings. NOTE: C-Pen Core is a service, not an app. There is thus no app icon.

Make sure that the Enable Input Method check box is selected/active.
Click on keyboard settings icon in the top bar right corner.
Click Show C-Pen Core. If the available option is Hide C-Pen Core then leave it as is.
Now there´s a floating C-Pen icon on the desktop (left lower corner in the image below).
Connecting the C-Pen makes the C icon turn blue.

How to identify USB connction on MAC

To check if there is a physical connection for TS1.

This is done viewing the System Report.

Click on the Apple logo in the upper left corner then select About This MAC.
Select System Report.
In the under Hardware section, click on USB.
Expand the USB Device Tree and locate C-Pen TS1.

If C-Pen TS1 exist, then the physical connection is OK.

If the C-Pen TS1 does not exist there is a physical connection problem. Try to connect the TS1 to another USB port and/or test it on another computer to verify it.

NOTE: System Report\Hardware\USB list will have to be refreshed at each new connection. Exit it an re-enter the USB Device Tree list.

Assuming that the C-Pen TS1 does exist in the USB Device Tree, then the problem is caused by software.

One thing to check is the VDCAssistant. If it is running, kill it. To do this, open Terminal and run command sudo killall VDCAssistant (provide password when prompted). Check this article for more details if required.
Make an SMC Reset.

Does the pen(s) work with USB-C?

USB-C is a physical specification compatible with the earlier protocols used by the various C-PEN models.
A USB-C to USB-A adapter is however required.
