dll cannot be loaded in other machines

Dear all,

I am a very new beginner to the c/c++ programming. I wrote some C code and compiled it to a dll which is used as a plugin in another application. The problem I have now is that the dll compiled using the Intel C++ Compiler 19.0 loads fine to the application in my laptop where the dll is compiled, but it could not be loaded to the same application ("could not load the plugin") in two other Wintel machines. This happens even if I stripped off all machine-specific options in the compilation. On the other hand, the dll compiled using Visual C++ compiler can be loaded to multiple Wintel machines without problems. I much prefer the Intel version of the dll since the application runs much faster with it (when it works, that is). The followings are some details.

* programing language: C (not C++);
* environment: Microsoft Visual Studio 2017 Community Version + Intel Parallel Studio XE 2019;
* machine used to compile the dll: notebook, Win10 (64bit), Intel Core i7-8550U CPU (Kaby Lake R);
* machines to be tested: (1) desktop, Win7 (64bit), Intel Core i7-6700K CPU (Skylake); (2) desktop, Win10 (64bit), Intel Core i7-8700 CPU (Coffee Lake).

The code is compiled using either the Intel compiler or the MS Visual compiler, both are done in MS VS2017. I did not use command lines.

The compilation options are the follows.

/MP /GS- /TC /W3 /Zc:wchar_t- /Zi /Od /Fd"x64\Release\vc141.pdb" /fp:precise /D "NDEBUG" /D "MSLE8C_EXPORTS" /D "_WINDOWS" /D "_USRDLL" /D "_WINDLL" /D "_UNICODE" /D "UNICODE" /Zc:forScope- /MD /FC /Fa"x64\Release\" /nologo /Fo"x64\Release\" /Qprof-dir "x64\Release\" /Fp"x64\Release\msle8c.pch" 

I'll appreciate if anyone can share insights. Thanks in advance.

I dont see any command line options which could be fail to run on another platform. Not so sure what happened in your ENV.

you can use the dependency walker to find which dll are missing.

Thanks to Viet and Vladimir for the replies and suggestions. Here is the update.

(1) In one of the desktops that previously didn't load the dll, I installed VS 2017 and Intel Parallel Studio XE 2019. After the installation, the dll, which is compiled in the notebook, can now be loaded successfully. I think it indicates that the dll requires some libraries that come with the VS and/or the Intel Studio.

(2) In another desktop that does not have the VS and the Studio, the dll still does not load. I run the dependency walker but do not know how to interpret the results. In the follows I cut and paste a relevant part of the log file. Note that MSLE8C.DLL is the dll I compiled and tried to load. Any guidance will be appreciated!
