# Help with missing WIBUCM32.dll

## When I try to start WATCHOUT, I get the following error message "The program can't start becauseWIBUCM32.dll is missing from your computer"?

The WIBUCM32.dll is related to the encryption/decryption of the WATCHOUT USB license key. Re-installing WATCHOUT will typically not resolve this issue. There are two ways to solve this:

**WATCHOUT v5 and older:**

Go to the WATCHOUT program install folder: yourProgramPath/Dataton\>KeyInstaller Inside that folder, there is an .exe file: CodeMeterRuntime32.exe. Running this will replace the missing dll file.

**WATCHOUT v6 and newer:**

Download and install a new version of CodeMeter by Wibu: [https://www.wibu.com/support/user/downloads-user-software.html](https://www.wibu.com/support/user/downloads-user-software.html)
