Record the exact filename and application
MSVCP140.dll and VCRUNTIME140.dll errors can involve the runtime needed by applications built with Visual C++. Copy the entire missing filename, application version and installation source. Similar-looking DLL names do not necessarily have identical requirements.
Distinguish an application that failed after an update from one that has never launched. For a game, note whether the launcher itself fails or the game fails after pressing Play.
Do not download a loose DLL
Copying a search-result DLL into System32 or the application folder can add a malicious, mismatched or incorrectly versioned file. A matching filename is not proof of a trusted component.
Use Microsoft’s supported Visual C++ Redistributable page and the application vendor’s requirements. Several installed redistributable entries are not automatically duplicates; removing them all can break unrelated software.
Match the application architecture
| Application | Package to investigate |
|---|---|
| x86 | x86 redistributable |
| x64 | x64 redistributable |
| ARM64 | Official ARM64 support guidance |
| Older application | Vendor-specified runtime generation |
A 64-bit Windows installation can still run a 32-bit application needing x86. Conversely, every PC does not automatically need both packages. If you do not know the app architecture, check its official requirements rather than guessing from the PC’s processor alone.
Repair or install, then retest consistently
Close the application and launcher. Check the publisher of the official installer. If the matching component is already present, review its available repair option; otherwise install the supported package required by the app. Save work before any requested restart.
Launch from the same shortcut under the same account. If the message changes to another filename, record that new result. Repeating the original installer without reading the new error may miss a different dependency.
Check application files if the problem remains
Use the launcher’s file-verification feature or the vendor’s application repair process when available. If security software quarantined a file, inspect the event and confirm the application source. Do not disable protection or restore a flagged file blindly.
One failing app usually calls for app-specific evidence rather than a Windows reset. If several Windows components also fail, the DISM and SFC guide offers a separate system-file investigation.
Share a precise, private support record
Include the app version, Windows version, architecture, package installed and complete error. Keep product keys and account credentials out of the report. A successful runtime installation and a successful application launch are two different outcomes; verify both before declaring the repair complete.
