This error can occur if the Visual Studio 2005 Runtime Libraries are not installed on the machine. This can occur if:
  • The Windows Installer on the machine is older than version 3.1
  • The user running MATLAB does not have administrative rights
  • MATLAB is not started with the matlab.bat file from $MATLAB\bin (where $MATLAB is the installation folder for MATLAB)
To resolve this error, run the following executable file with administrator rights:
$MATLAB\bin\win32\vcredist_x86.exe (for 32-bit MATLAB)
$MATLAB\bin\win64\vcredist_x64.exe (for 64-bit MATLAB)
You should see the Visual Studio 2005 Runtime library installer appear and complete the installation. If you see the following errors:
ERROR: MS visual C++ 2005 redistributable:
Error 1723. There is a problem with this Windows Installer package. A DLL required for this install to complete could not be run. Contact your support personnel or package vendor.
ERROR: VCRT_check.exe failed: MFC80U.DLL library could not be located.
You will need to update the Windows Installer. For more details see the Bug Report here:
If this does not solve the problem, follow the steps in the documentation in section "External Interfaces" to manually register MATLAB using the 'matlab /regserver' command (Step: "Register MATLAB as a COM Server").
These files are not included as of R2016b and after. If you experience this error on those releases, please contact support.
