Cinema 4D crashes or freezes when switching windows with a pen tablet

Problem Cinema 4D crashes or freezes on Windows when you switch between Cinema 4D and another window (such as File Explorer, a browser, or another application) while a pen tablet is connected. The crash can also happen when clicking back into the Cinema 4D viewport after using another app.

This type of crash is usually not a Cinema 4D bug. It is typically a conflict between the two ways Windows can deliver tablet input to applications: the older WinTab API and the newer Windows Ink API. Rapidly switching focus between Cinema 4D and other windows can trigger the conflict and bring Cinema 4D down with it. This affects pen tablets in general, not any single brand, so the steps below apply whether you are using a Wacom, Huion, XP-Pen, Gaomon, Veikk, Xencelabs, or other tablet.

Solution The fastest fix for most users is to disable Windows Ink in your tablet driver utility. If that does not resolve it, update your tablet driver to the latest version, check for leftover tablet drivers from other manufacturers, and as a last test, temporarily rename wintab32.dll to confirm whether the DLL is involved.

Step 1: Disable Windows Ink in your tablet driver

Almost every modern tablet driver has a toggle that controls whether the tablet sends input through Windows Ink. Turning this off forces the tablet to use WinTab exclusively, which resolves the crash for the majority of users. The exact location of the setting depends on which tablet you are using.

+Wacom

Newer Wacom drivers ship the Wacom Center app, while older installs still use the legacy Wacom Tablet Properties panel. Use whichever one is on your system.

Wacom Center (current driver):

  1. Open the Windows Start menu and search for Wacom Center, then open it.
  2. Select your pen in the device list.
  3. Open the Advanced flyout menu on the right.
  4. Turn off the Windows Ink toggle.
  5. Restart Cinema 4D and try reproducing the crash.

Wacom Tablet Properties (legacy driver):

  1. Open the Windows Start menu and search for Wacom Tablet Properties, then open it.
  2. At the top of the window, click the Pen tab.
  3. Click the Mapping button. On Cintiq pen displays, this option lives on the Calibrate tab instead.
  4. Uncheck the box labeled Use Windows Ink.
  5. Click OK to save the change.
  6. Restart Cinema 4D and try reproducing the crash.

If you use multiple Wacom devices (for example a pen tablet and a pen display), repeat these steps for each device listed at the top of the panel.

+Huion
  1. Open the HuionTablet driver utility from the Start menu.
  2. Click the Pen Settings (or Tablet Settings, depending on driver version) section.
  3. Uncheck the box labeled Enable Windows Ink.
  4. Apply the change and restart your computer for it to take full effect.
  5. Launch Cinema 4D and try reproducing the crash.
+XP-Pen
  1. Open the Pentablet driver utility.
  2. Switch to the Pen Settings section.
  3. Locate the Windows Ink checkbox and uncheck it.
  4. Apply the change and restart Cinema 4D.
+Xencelabs
  1. Open the Xencelabs Pen Tablet app from the Start menu, or press the assigned button on your tablet to open it.
  2. In the Xencelabs Setting Tool, locate the Windows Ink checkbox.
  3. Uncheck it to disable Windows Ink globally. (You can also disable it on a per-application basis by adding Cinema 4D to the application list and unchecking Windows Ink only for that entry.)
  4. Apply the change and restart Cinema 4D.
+Other tablet brands

For Gaomon, Veikk, Ugee, and other tablet brands, open the driver utility that shipped with your tablet and look for a setting labeled Windows Ink, Use Windows Ink, Enable Windows Ink, or Support TabletPC. Disable it, then restart Cinema 4D. If you cannot find the option, check your tablet manufacturer's support site for instructions specific to your driver version.

Step 2: Update your tablet driver

Driver updates frequently include fixes for WinTab and Windows Ink interoperability problems that can cause host applications like Cinema 4D to crash. If you are running an older driver, install the latest version from your tablet manufacturer's official website.

  1. Go to your tablet manufacturer's official driver download page and download the latest Windows driver for your model.
  2. Uninstall your current tablet driver from Settings > Apps > Installed apps.
  3. Restart your computer.
  4. Install the new driver and reboot once more.
  5. Reapply the Windows Ink setting from Step 1, since a driver reinstall often resets it.
Tip Stick with the driver from your tablet manufacturer's official site. Drivers bundled by Windows Update or pulled from third-party sites are often older and can be missing the fixes you need.

Step 3: Remove leftover drivers from other tablets

If more than one tablet driver has ever been installed on this machine, residual wintab32.dll files from older installers can remain on the system and override the driver for the tablet you are currently using. When that happens, Cinema 4D can end up loading a WinTab implementation that does not match your connected tablet, which leads to instability and crashes. This is one of the most common causes of stubborn tablet crashes that survive a driver reinstall.

  1. Open Settings > Apps > Installed apps.
  2. Look for any tablet driver entries from manufacturers other than the tablet you are currently using (Wacom, Huion, XP-Pen, Gaomon, Veikk, Xencelabs, and similar).
  3. Uninstall each one.
  4. Restart your computer.
  5. Reinstall the driver for your current tablet so its WinTab file is the active one on the system.

Step 4: Rename wintab32.dll as a diagnostic test

If the crash continues after the steps above, you can temporarily rename the WinTab DLL to confirm whether it is the source of the problem. This is a quick, fully reversible test, not a permanent fix.

Important Renaming this file disables tablet pressure sensitivity for any application that relies on WinTab while the file is renamed. This is fine as a short test, but rename the file back when you are done so your tablet works normally in other applications.
  1. Close Cinema 4D and any other application that uses your tablet.
  2. Open File Explorer and navigate to C:\Windows\System32.
  3. Find the file wintab32.dll.
  4. Right-click it and choose Rename. Rename it to wintab32_.dll. Windows will ask for administrator permission, which you should approve.
  5. Launch Cinema 4D and try to reproduce the crash by switching windows the way you normally would.
  6. If the crash stops, the WinTab DLL is involved. The most likely cause is a stale or conflicting WinTab installation, so reinstalling the Wacom driver after cleaning up any leftover tablet software from Step 3 is the right next step.
  7. When finished, rename wintab32_.dll back to wintab32.dll to restore tablet functionality in other applications.

Still crashing? Send us your bug report files

If Cinema 4D continues to crash after working through the steps above, please send us the bug report files from your Cinema 4D preferences folder so we can investigate further.

  1. In Cinema 4D, go to Edit > Preferences.
  2. At the bottom of the Preferences window, click Open Preferences Folder. This opens your Cinema 4D preferences folder in File Explorer.
  3. Inside that folder, look for a subfolder called _BugReports.
  4. Zip the entire _BugReports folder and attach it to your support ticket. The crash dumps inside that folder are what we need to dig into the cause.

TL;DR

  • Cause: a conflict between the WinTab and Windows Ink tablet input APIs on Windows, often triggered by quickly switching focus between Cinema 4D and another window. Applies to any pen tablet brand.
  • First fix: disable the Windows Ink option in your tablet driver utility (Wacom Tablet Properties, HuionTablet, XP-Pen Pentablet, etc.).
  • If that does not help: update your tablet driver from the manufacturer's official site, uninstall any leftover drivers from previous tablets, and as a diagnostic test, rename C:\Windows\System32\wintab32.dll to wintab32_.dll to confirm whether the WinTab DLL is involved.
  • Still crashing? Send the _BugReports folder from your Cinema 4D preferences directory so support can dig into the cause.

If you are still experiencing issues after following these steps, please submit a support ticket, and our team will be happy to assist you further.
