Hi everyone,

Please, I have an application that uses MATLAB Runtime 9.9 (with Windows Server 2019 Std) and I'm facing the following error message:

"Failed to create COM objectMatlabWrapper.wrapper: Automation errorThe specified module could no be found".

Please, any tip to solve this issue?

Thanks.

Hello @Jean,

You can ensure that the following COM components are registered: 'mwcomutil.dll' and 'mwcommgr.dll'.

If they are not registered then you can register them using the command 'mwregsvr', by following these steps:

Open windows command prompt.
Change the directory to 'C:\Program Files\MATLAB\MATLAB Runtime\<Your MATLAB Release>\bin\win64'
Execute the commands: 'mwregsvr mwcomutil.dll' and 'mwregsvr mwcommgr.dll'

You can refer this documentation for more details on command 'mwregsvr'.
