LoadLibrary fails

Question

I am tying to create WebApp (using Asp.Net Core 2.2) for existing desktop app which is written in C++. From my webapp I am trying to invoke the process. Inside the c++ exe it is trying to load some DLL which is failing in my case. Same thing is working fine when i directly invoke the desktop app from cmd.

 

Please suggest how to rectify this problem.

 

This is my webapp code where i am invoking the exe -

ProcessStartInfo sprbProcessInfo = new ProcessStartInfo();
sprbProcessInfo.FileName = @"C:\Program Files\SmartPlant\Interop Publisher\SPRB.exe";
sprbProcessInfo.Arguments = "\"" + strSrcFileFullPath + "\"" + " -b " + "\"" + strDestFileFullPath + "\"";
sprbProcessInfo.RedirectStandardOutput = true;
sprbProcessInfo.UseShellExecute = false;
Process oTranslateProcess = new Process();
oTranslateProcess.StartInfo = sprbProcessInfo;
oTranslateProcess.Start();
oTranslateProcess.WaitForExit();
oTranslateProcess.Close();

This is what I am trying to do in my exe -

 

LoadLibrary (csSolidsFile); ===> this call is failing
