When starting Anki, you may receive a message like the following:
- Error loading Python DLL
- The program can't start because api-ms-win.... is missing
- Failed to execute script runanki
- Failed to execute script pyi_rth_multiprocessing
- Failed to execute script pyi_rth_win32comgenpy
These errors are usually because your computer is missing a Windows update or Windows library.
Please open Windows update, and ensure your system has all updates installed. If any needed to be installed, please restart your device after installing.
On Windows 7/8, you may need to manually install extra updates. Please try:
Please see display issues.
If you get a LoadLibrary failed with error 126, this may be caused by the toolkit Anki is built on having trouble with multiple displays
Third-party software on your machine may prevent Anki from loading. You can try adding an exception to Anki, or temporarily disabling your antivirus/firewall to see if it helps.
Some users have reported that Anki did not run for them until they right-clicked on the Anki icon and chose "Run as administrator". Anki stores all of its data in your user folder, and should not need administrator privileges, but it's something you can try if you've exhausted other options.
Starting Anki from a terminal may reveal a bit more information about some errors. After installing the latest Anki version and ensuring all Windows updates are installed, instead of running Anki directly, use Start>Run and type cmd.exe. When a console window appears, type
cd \program files\anki & anki-console
Presumably Anki will fail to open like before, but it may reveal something about what is causing the problem.
If you are unable to start Anki after trying the above workarounds, you have two remaining options:
- You can try running from Python.
- You can try an older Anki version built with an older toolkit, such as 2.1.35-alternate, and 2.1.15.
