Diagnose a Corrupted MATLAB Runtime

This example shows a typical diagnostic procedure you might follow to solve a problem starting server prod_server_x.

After you issue the command:

mps-start prod_server_x

from within the server instance folder (prod_server_x), you get the following error:

Server process exited with return code: 4
(check logs for more information)
Error while waiting for server to start: The I/O operation
has been aborted because of either a thread exit 
or an application request

To solve this issue, you might check the log files for more detailed messages, as follows:

1. Navigate to the server instance folder (prod_server_x) and open the log folder.

2. Open main.err with any text editor. Note the following message listed under Server startup error:

   Dynamic exception type: class std::runtime_error
   std::exception::what: bad MATLAB Runtime installation: 
   C:\Program Files\MATLAB\MATLAB Runtime\v82 
   (C:\Program Files\MATLAB\MATLAB Runtime\v82\bin\
   win64\mps_worker_app could not be found)

3. The message indicates the installation of the MATLAB^® Runtime is incomplete or has been corrupted. To solve this problem, reinstall the MATLAB Runtime.
