Dll 39-qmsl-msvc10r.dll 39- Page
Based on analysis of similar Qualcomm tool error logs, 39- often indicates:
| Code Segment | Likely Meaning |
|---------------|----------------|
| 3 | Subsystem: Communication Layer |
| 9- | Specific failure: DLL loading failure or missing export function |
In plain English: "The application (error code 39-) has attempted to access a function inside qmsl-msvc10r.dll, but the DLL is either missing, corrupt, or incompatible with your current Windows architecture."
Third-party services or startup programs can interfere with DLL loading.
Warning: Many DLL download websites host outdated, malicious, or incorrect versions of files. Never download qmsl-msvc10r.dll from a third-party DLL repository.
The only safe source is the original software vendor (Keysight, NI, Rohde & Schwarz, etc.) or your original installation media.
If you have a backup of the file from a known clean system, you can restore it to the correct folder, but always verify the digital signature:
| Component | Meaning |
|-----------|---------|
| qmsl | Quick Measurement Software Library (likely from National Instruments, Keysight, or a similar instrumentation vendor) |
| msvc10r | Microsoft Visual C++ 2010 Redistributable runtime |
| .dll | Dynamic Link Library |
This DLL file serves as a bridge between measurement hardware (oscilloscopes, spectrum analyzers, data loggers) and software applications that control or read data from that hardware.
The 39- is not a standard Windows system error code (which are numbers like 0x80070002). Instead, it is likely a custom application error code or log reference ID used by the software attempting to call qmsl-msvc10r.dll.
The qmsl-msvc10r.dll file, despite its cryptic name, plays a vital role in connecting test-and-measurement software to hardware devices. Errors involving this file usually stem from missing VC++ runtimes, corrupt installations, or accidental deletions. By following the systematic troubleshooting steps outlined above—reinstalling the parent software, repairing Visual C++ Redistributables, and avoiding dubious DLL download sites—you can resolve the issue safely and efficiently. dll 39-qmsl-msvc10r.dll 39-
Remember: The unusual 39- prefix/suffix in your search query is not part of the filename. Focus your troubleshooting on qmsl-msvc10r.dll, and always obtain it from trusted, official sources.

QMSL_MSVC10R.dll is a core component of the Qualcomm Manufacturing Support Library (QMSL), a proprietary set of libraries used for automating factory testing and calibration of mobile devices. What it Does
The library provides the software interface for high-level tasks like:
RF Tuning & Calibration: Controlling radio frequency paths for 2G/3G/4G/5G technologies.
Device Management: Reading or writing IMEI numbers, serial numbers, and NV (Non-Volatile) items.
Testing: Placing devices into factory test modes to issue DIAG commands and validate compliance metrics. Technical Details
Naming: The "MSVC10R" suffix indicates it was compiled using Microsoft Visual C++ 2010 (v10) in its "Release" configuration.
Usage: It is primarily used by developers and manufacturers alongside tools like QPST (Qualcomm Product Support Tools), QXDM, or custom automation scripts (e.g., Python scripts using ctypes to load the DLL).
Common Errors: Errors like "missing" or "not found" usually occur when trying to run firmware flashing or diagnostic tools without the necessary support libraries installed. How to Fix Related Issues If you encounter an error stating this file is missing: Based on analysis of similar Qualcomm tool error
Reinstall the Application: Reinstalling the specific tool (like QPST or QXDM) often replaces the missing file.
Install Visual C++ Redistributable: Ensure you have the Microsoft Visual C++ 2010 Redistributable Package installed, as this DLL depends on it to run.
Safety Warning: Avoid downloading individual DLL files from third-party "DLL provider" sites, as these files can sometimes be malicious or incompatible with your system. If you're trying to fix a specific error, let me know: What program were you opening? The exact error message you see. Qualcomm Manufacturing Support Library (QMSL) Download
The specific file dll 39-qmsl-msvc10r.dll 39- appears to be a fragmented or slightly misnamed reference to a component associated with Qualcomm Mobile Software (QMSL), likely compiled using Microsoft Visual C++ 2010 (msvc10r).
Files with this naming convention are typically part of driver packages or diagnostic tools for devices using Qualcomm chipsets, such as smartphones or wireless modems. Potential Context and Origins
Qualcomm Product Support Tool (QPST): This DLL is often found in the installation directories of Qualcomm-related software like QPST or the Qualcomm Service Tool. These tools are used for low-level tasks like flashing firmware, restoring IMEI data, or changing network bands on mobile devices.
Microsoft Visual C++ Redistributable: The "msvc10r" suffix indicates a dependency on the Microsoft Visual C++ 2010 Runtime. If you are receiving an error that this file is missing, installing the 2010 (x86) redistributable package may resolve the issue. Troubleshooting Missing DLL Errors
If you are seeing an error related to this specific file, follow these steps:
Reinstall the Primary Software: If the error occurs when opening a specific mobile repair or flashing tool, reinstalling that program is the most reliable way to restore missing DLLs.
Install Visual C++ Runtimes: Ensure you have the Visual C++ 2010 Redistributable installed, as the DLL relies on these libraries to execute. | Component | Meaning | |-----------|---------| | qmsl
Run System File Checker: You can use the Windows SFC tool by typing sfc /scannow in an Administrator Command Prompt to repair corrupted system files.
Avoid Manual Downloads: Never download DLL files from third-party "DLL fixer" sites. These files are often outdated or can contain malware. Instead, source them from the original software developer or official Microsoft installers.
Are you experiencing a specific error message or is a particular program failing to launch because of this file?
It looks like you’re referencing a DLL file with a name that follows a pattern typical of proprietary or legacy manufacturing/automation software, specifically possibly related to QMS (Quality Management Systems) or measurement equipment (e.g., Zeiss, Mitutoyo, or similar coordinate measuring machine software).
However, 39-qmsl-msvc10r.dll is not a standard Windows system file and doesn’t appear in public Microsoft, Visual Studio, or common third-party library databases.
Here’s a helpful general guide for dealing with a DLL like this, since it’s likely environment‑specific.
In some cases, DLLs need to be registered in the Windows Registry:
The search string dll 39-qmsl-msvc10r.dll 39- is almost certainly a copy-paste artifact from a forum, error log, or corrupted display where:
Important: The actual filename does not contain 39- at the beginning or end. You should search for and reference qmsl-msvc10r.dll only.
