I have compiled a python package for a matlab function. But when i run the same by initializing the mcr instance in python i get the error below. I suspect that the startup.m script is not being called and hence Matlab is not able to find the .dll file. How can this be fixed ?
I get this error while executing the matlab function from a flask app. But it runs without any errors when executed through a standalone python script or through the interpreter.
PS: I have a feeling that if i somehow call startup.m in my main function then it should solve the problem.

This issue is potentially caused by spaces in the Windows "%temp%" directory path. Once your Windows "%temp%" directory path does not have a space, the script should be able to execute without error. Spaces in the Windows "%temp%" directory may be caused by spaces in the Windows username.
Here "C:\Program Files\" seems to contain a space character. Changing to a directory without the "space character" in the path might help resolve this issue.
This is a known issue and you can find a workaround in the following bug report:
