Do NOT try to uninstall aggressively. Instead:
When developers write software in C++ using Microsoft Visual Studio 2008 (with Service Pack 1), they rely on a set of standard runtime libraries—code that handles memory management, input/output, math operations, and exception handling. Rather than bundling those libraries into every single application (which would bloat file sizes and waste disk space), Microsoft packages them into shared “redistributable” installers.
Microsoft Visual C++ 2008 SP1 Redistributable (MFC Security Update) vcredist-x64-2008-sp1-x64.exe
| Attribute | Details | |-----------|---------| | | Microsoft Visual C++ 2008 SP1 Redistributable Package (x64) | | Key DLLs | msvcr90.dll , msvcp90.dll , mfc90.dll | | Common size | ~4–6 MB (compressed) | | Installation path | Typically C:\Windows\System32\ (for 64-bit DLLs) | | Side-by-side (SxS) | Uses WinSxS folder for versioning (e.g., x86_microsoft.vc90.crt_… ) |
You do not need this file for the sake of having it. You need it because another program you use requires it. Do NOT try to uninstall aggressively
You tried to run the x64 version on a 32-bit version of Windows.
Let’s decode the name:
In simplest terms, Without these libraries, any software programmed with that specific version of Visual Studio will fail to run on your computer.
