dll files not found in Windows 10

[dondilworth]

My program requires some dll files, which I install with

w_fcompxe_redist_ia32_2013_sp1.1.139.msm

with Advanced Installer.  The user has to run the msi file, and then the program works.  This runs on XP, and Windows 7.  I upgraded some W7 PCs to W10, and the program still works.  So far, so good.

But if I install everything on a new W10 machine that has never seen my program before, I get a message that the program cannot start because libifcoremd.dll (and three others) are missing.  But the files are indeed on the machine in

C:\Program Files (x86)\Common Files\Intel\Shared Libraries\redist\intel64\compiler.

I checked them, and deselected the read-only attribute, but they still don't work.  Any ideas?

As you were.  Right-click the .exe file, Properties, Run as Administrator.  Then it works.
