Fix QFIL Error: QMSL_MSVC10R.dll

Error message

Restore QCN Fail Unable to load DLL 'QMSL_MSVC10R.dll'. The specified module could not be found. (Exception from HRESULT: 0x8007007E)

Cause

According to the reference, Windows lacks the Microsoft Visual C++ 2010 (x86) runtime components that QFIL/QPST software requires to read QMSL library files.

Ultimate solution: Install Visual C++ All-in-One

  1. Download the package. Search and download Visual C++ Redistributable Runtimes All-in-One from trusted technology sites, such as TechPowerUp or MajorGeeks.
  2. Extract files. Extract the downloaded ZIP file into a new folder.
  3. Run the installer. Search files install_all.bat, right click, then select Run as administrator.
  4. Wait for the process to complete. The Command Prompt window will install the Visual C++ version automatically. Wait until the window closes itself.
  5. Restart the computer. Restart so that Windows recognizes the newly installed DLL file.

Alternative solution if the error still appears

A. Copy the DLL to the QFIL folder

  1. Search files QMSL_MSVC10R.dll on the computer or inside the QPST installation folder.
  2. Copy (Copy) the file.
  3. Paste directly into the main folder where QFIL is run, usually in:
    C:\Program Files (x86)\Qualcomm\QPST\bin\

B. Update QPST to the latest version

Older versions of QPST may have compatibility issues with Windows 10/11. The reference suggests uninstalling the old QPST and installing a newer version, for example QPST version 2.7.460 or above.

Notes from references: If the DLL file is considered to be a fake threat during the flashing process, sources recommend temporarily disabling antivirus or Windows Defender. Make sure the file actually comes from a trusted source before running it.
