Wintab
Wintab (WinTab32.dll) is an ancient API created by Wacom to
communicate tablet-like devices with Windows programs. Before Windows 8,
this was the "de facto" standard used to access pressure
information from tablets created by Wacom and other brands. Since
Windows 8, Microsoft introduced a new official API: the Pointer
API/Windows Ink.
Since Aseprite v1.2.34 (and v1.3-beta12), as we've received a
lot of crash reports related to buggy third-party WinTab32.dlls,
we've switched to the Windows Pointer API by default. (The Wintab
option is still available from the Tablet options.)
In previous versions of Aseprite, we tried to load this Wintab library initially, but it could cause the program to crash randomly. Sometimes you can solve this reinstalling drivers, restarting Windows, using the Pointer API from Tablet options, or just disabling Wintab usage from Edit > Preferences > Tablet (or from Edit > Preferences > Experimental in older versions):
Aseprite doesn't start
If you cannot even start the program, you can execute Aseprite with
the -disable-wintab parameter (available since Aseprite v1.2):
"C:\Program Files\Aseprite\Aseprite.exe" -disable-wintab
This will avoid loading WinTab32.dll file. Your tablet might not
work correctly, but at least Aseprite can be executed and used with
your mouse/trackpad (or you can try the Windows Pointer API).
Steam
On Steam you can add the -disable-wintab option in the Aseprite launch options:
-
Right-click Aseprite in your Steam library and open its "Properties":
-
Click the "Set Launch Options" button:
-
Add the
-disable-wintaboption and press "OK":
