What is msvcp100.dll?
MSVCP100.dll implements C++ standard-library functions used by software built with Visual Studio 2010. The 100 generation is separate from MSVCP110, MSVCP120, and MSVCP140. Installing a newer runtime does not necessarily supply this older file.
A setup program should install the correct Visual C++ 2010 redistributable alongside the application. The file can be missing after a partial uninstall, disk cleanup, failed setup, or security quarantine.
Which source should provide a msvcp100.dll download?
Use Microsoft's Visual C++ 2010 SP1 Redistributable security update page. Microsoft may require choosing the x86 or x64 installer after opening the page. We link to the official details page rather than repackaging the installer.
Install x86 for a 32-bit application and x64 for a 64-bit application. On a 64-bit PC, an older 32-bit program still requires the x86 runtime.
Check the evidence before a msvcp100.dll download
Start with the full download error and the path of the program that displayed it. A DLL error raised from a game folder usually points to that game's prerequisites or installation, while an error from an unrelated desktop program may point to a separate runtime. Search results for the filename cannot see that local context.
If a copy already exists, do not replace it with the first download listing you find. Open its file properties and review the location, digital-signature tab, product name, and modified date. Compare those details with the application installer or publisher documentation. A valid signature can support an origin check, but an unsigned file is not automatically malicious and a familiar filename is not automatically trustworthy.
Create a restore point or back up important application data before system-level repairs. Avoid registry cleaners and one-click download fixer programs that do not disclose exactly what they change. A controlled package repair is easier to reverse and easier to diagnose than several simultaneous replacements.
msvcp100.dll download and safe repair checklist
Use this msvcp100.dll download and safe repair checklist to choose a recovery method based on evidence, not urgency. The goal is to restore the component expected by the affected application while preserving its related files, update path, and architecture.
| Situation | Recommended decision |
|---|---|
| The error appeared on the first launch | Install or repair Visual C++ 2010 SP1 Redistributable and then repair the application that displayed the message. |
| The error began after an update | Verify the affected product first because an interrupted update can leave a mixed set of executable and DLL versions. |
| The file exists but an entry point is missing | Remove manual replacement copies and restore the build selected by Microsoft or the original software package. |
| Security software quarantined the file | Review the detection, file path, signature, and original installer before deciding whether any restoration is appropriate. |
A responsible msvcp100.dll download and safe repair process also records what changed. Keep the installer name, source domain, architecture, and time of repair. If the problem returns, those details help distinguish a damaged package from an application update, security action, or unsupported modification.
How to fix msvcp100.dll download and missing-file errors
- 1
Confirm the filename
Make sure the message says MSVCP100.dll, not MSVCR100.dll or MSVCP110.dll.
- 2
Open Microsoft's 2010 package page
Choose the redistributable architecture required by the application.
- 3
Run Install or Repair
Use an administrator account and allow the Microsoft installer to complete.
- 4
Restart the application
Close all related processes and open the application again after installation.
- 5
Repair or reinstall the app
If the runtime is present, the application's own installation may be damaged.
Common msvcp100.dll download and repair scenarios
The safest msvcp100.dll download and safe repair path depends on when the failure started. Work through the scenario that matches your system instead of applying every possible fix at once.
After installing or moving an application
Portable copies, restored backups, and manually moved game folders can omit prerequisites that a normal installer would add. Return to the original setup or launcher, install its dependencies, and keep the application in a supported location. Copying only the executable and a few DLL files rarely reproduces a complete installation.
After Windows or software maintenance
An update can expose an older local DLL that previously loaded by accident. Repair Visual C++ 2010 SP1 Redistributable, then verify the affected application so its executable and supporting files come from the same release. Avoid rolling back unrelated Windows updates unless the publisher documents a confirmed compatibility issue.
After a security alert or modification
Do not treat an antivirus block as a routine missing-file problem. Record the detection, scan the system, and remove unofficial loaders, wrappers, or copied libraries. If the software is legitimate, recover it from its original publisher or store instead of searching for a replacement with the same filename.
This msvcp100.dll download and safe repair guidance is intentionally source-first: the correct outcome is a working, maintainable application, not merely a folder that contains a file named msvcp100.dll.
Common msvcp100.dll download error messages
MSVCP100.dll is missing from your computer.The code execution cannot proceed because MSVCP100.dll was not found.This application failed to start because MSVCP100.dll was not found.
MSVCR100.dll and MSVCP100.dll are related but not interchangeable. The official redistributable installs the coordinated Visual C++ 2010 components.
msvcp100.dll download compatibility for 32-bit and 64-bit Windows
Visual C++ 2010 is a legacy runtime retained for applications built against it. Current Windows versions can often run these applications, but the application itself may have additional compatibility limits.
The x86 package is not obsolete simply because Windows is 64-bit. Match the application process, not only the operating system.
How to confirm the msvcp100.dll download repair worked
Restart the affected application from its normal launcher and repeat the action that previously produced the download error. A successful launch is stronger evidence than finding a file with the expected name. Check that the original missing-file or entry-point message is gone and that no new dependency error has replaced it.
If another DLL download is now requested, return to the owning package rather than downloading files one by one. A sequence of missing components usually means a redistributable, DirectX prerequisite, game depot, or application installation is incomplete. Record each installer used so you can undo changes or provide accurate details to the software publisher's support team.
Do not choose a msvcp100.dll download by name alone
Do not rename another MSVCP file to MSVCP100.dll. The numeric suffix identifies an ABI generation, not an optional filename.
Reject any download that hides its publisher, package context, architecture, or update path.
msvcp100.dll download FAQ
Will Visual C++ 2015-2022 install MSVCP100.dll?
No. Visual C++ 2010 is a separate runtime generation and may need its own redistributable.
Do I need MSVCR100.dll too?
Many Visual C++ 2010 applications use both files. The official package installs the required runtime set.
Is the x86 installer only for 32-bit Windows?
No. It is also required by 32-bit applications running on 64-bit Windows.
Should I replace an existing MSVCP100.dll?
Use the Microsoft installer's Repair option instead of manually overwriting an existing file.
