kernel32.dll is one of the core files of Windows itself - every program uses it. That is why a "kernel32.dll error" almost never means the file is missing: it means a program asked this very old, very stable file for something it cannot give - or something else in the system is broken. The right fix depends on which message you see.
Quick answer
If the message says "The procedure entry point ... could not be located in kernel32.dll" - the program is too new for your version of Windows (typical when running modern apps on Windows 7). Install the program version made for your Windows, or update Windows. For other kernel32 crashes, run sfc /scannow and a full malware scan - the file itself is almost never the problem.
"Entry point not found" means the app calls a function your Windows version does not have - most common on Windows 7 and older running current software.
Disk errors or failed updates can corrupt system libraries around kernel32 - crashes then get blamed on it.
Malware injects itself into running programs; when it misbehaves, the crash often lands in kernel32.dll even though the file is fine.
Random crashes naming kernel32 in unrelated programs are a classic symptom of faulty memory.
sfc /scannow and let it finish.DISM /Online /Cleanup-Image /RestoreHealth, then SFC again, then restart.mdsched, choose Restart now - the PC reboots into a RAM test.chkdsk /f and confirm the restart check.Do not do this: kernel32.dll is protected by Windows and restored by SFC from the component store. Downloading a replacement from a "DLL site" cannot help and is a classic malware vector - never do it for core system files.

SFC restores the genuine copy if it is ever damaged, and "entry point" errors are not file damage at all.
The program asked kernel32.dll for a function that exists only in newer Windows versions. The file is healthy - it is simply older than the program. Match the program version to your Windows, or update Windows.
Malware often patches or injects into system processes. After removal, leftover broken components can keep crashing - run SFC and DISM (method 2) to restore the system files to their genuine state.
