Problem running mexw64 file, missing .dll files

I am attempting to use a mex file but am running into issues with accessing .dll files. I am using Matlab 2017a on a Windows 7 x64. However, when I run the mex file, I receive the following errors:

Invalid MEX-file 'C:\...\Documents\MATLAB\Matlab Offline
Files SDK\mexPlex.mexw64': Missing dependent shared libraries:
'MSVCP80.dll' required by 'C:\...\Documents\MATLAB\Matlab
Offline Files SDK\mexPlex.mexw64'
'MSVCR80.dll' required by 'C:\...\Documents\MATLAB\Matlab
Offline Files SDK\mexPlex.mexw64'

I've tried reinstalling matlab and reinstalling Visual Studio C++ 2005 (supposedly contains these files?). Any assistance would be much appreciated.

I have the same problem:

Invalid MEX-file 'C:\...\Documents\MATLAB\VL_feat_Matlab\vlfeat-0.9.17\toolbox\mex\mexw64\vl_version.mexw64':
Missing dependent shared libraries:
'VCOMP90.DLL' required by

VCOMP90.DLL is from Microsoft Visual C++ 2008 SP1 Redistributable Package (x64)

MSVCR80.dll was part of Microsoft Visual C++ 2005 Redistributable. The 32 bit version of that is https://www.microsoft.com/en-ca/download/details.aspx?id=3387; the 64 bit is https://www.microsoft.com/en-ca/download/details.aspx?id=21254

I'm having this problem in Matlab 2017b. Did you ever find a solution for it?

[Walter Roberson]

You need to install the redistributables that I noted. vlfeat was compiled against old Visual Studios versions.

I am having a similar problem (MATLAB Answers: Error: Missing dependent shared libraries maplec.dll required

Any advice would be appreciated.

Jan, I don't understand your comment. I posted a link with a full description of my issue and question. Can you clarify what you want me to do?
