The DLL must reside in a specific folder (e.g., C:\Program Files (x86)\Qualcomm\bin) or be registered in the system PATH. Incorrect permissions (especially on Windows 10/11 protected folders) block loading.
Breaking down the name:
So this is almost certainly part of an older industrial measurement, metrology, or quality control software that depends on Visual C++ 2010 redistributables.
Contact the software/hardware vendor directly.
Search the full error message or the software name without the DLL name. The DLL is just a symptom – the root cause is a missing or broken QMS software installation. dll 39-qmsl-msvc10r.dll 39-
If the vendor no longer exists (common for legacy industrial software), your only reliable option is:
You will likely encounter this file if you have installed any of the following:
The 39- prefix in the error context usually appears inside diagnostic tools or command-line utilities when they fail to load this specific library. The DLL must reside in a specific folder (e
Some security suites flag Qualcomm DLLs as "potentially unwanted" due to their low-level hardware access. The software may quarantine the file, triggering error 39-.
For Windows Defender:
For third-party AV (Bitdefender, Kaspersky, McAfee): Consult your software’s quarantine log and restore the file. Breaking down the name:
If the software is already installed but missing this file, search your computer for any other DLLs with similar names (e.g., *qmsl*.dll).
The missing DLL might belong in the software’s main folder, not System32.
Check folders like:
If you find the file elsewhere, copy it to the application’s folder, then open Command Prompt as Administrator and run:
regsvr32 "C:\full\path\to\39-qmsl-msvc10r.dll"
But note: Not all DLLs are registerable. This one likely isn’t a COM DLL; it’s a plain dependency library.
