Unable to open awe_designer from Matlab

I am experiencing an issue opening the awe_designer through Matlab. I have the correct paths set and it is able to open the server, but I am getting the following errors within Matlab:

>> awe_designer
Using binary from win32-vc142-rel
Error using awe_designer
Error connecting to the AWE Server - Unable to start AWE_Server.exe - aborting

 

I wasn't able to find any similar issues or useful debug info in the logs. If you have any useful Debug steps or suggestions it would be helpful. Thanks!

Hi Brad,

Please try using awe_init to just start up AWE Server at first.

I expect the startup to look like this (assuming our newest release 8.2025.1):

>> awe_init
Using binary from win32-vc142-rel
Successfully connected to target: Native
There are a maximum of 16 static cores available.
4 instances are defined: Native, Native, Native, Native

ans =

    'C:\DSP Concepts\AWE Designer 8.2025.1 Pro'

----

If AWE Server is unable to start we need to try to figure out why.

Has it ever worked?  Was it working and suddenly stopped?  Some more context would be helpful.

Thanks,

Gary

Hey Gary,

Yes this was working in previous weeks on my environment, just this week I am having issue. I had been running 8.D.2.7 similar to the rest of my team, but I have gotten the latest 8.2025.1 release as well with issue. Note that awe_init has a similar failure:

>> awe_init
Using binary from win32-vc142-rel
Error using awe_init
Unable to start AWE_Server.exe - aborting

Hi Brad,

Does 8.D.2.7 still work?

My first recommendation would be to uninstall the new package using uninst.exe in the install location, and reinstall.

Thanks,

Gary

Hey Gary,

No, reverting to 8.D.2.7 still does not work. I have tried a re-installation of AWE and of MATLAB but no luck yet.

Thanks,

Brad

Hi Brad,

 

Did you check to make sure that your MATLAB path only contains references to a single installation of Audio Weaver?  When I need to switch AWE Versions, I usually reset the MATLAB Path to "Default" prior to adding the new folder.

Thanks,

Gary

Hey Gary,

Thanks for the response!Still no luck here with reverting the Matlab Paths and then pointing to the AWE Matlab root folder. I will continue to try some re-installation steps for Matlab and my environment.

Regards,

Brad

Hi Brad,

Can you launch AWE Server directly?

e.g.

"C:\DSP Concepts\AWE Designer 8.2025.1 Pro\Bin\win32-vc142-rel\AWE_Server.exe"

Double click on the icon in File Explorer.

What happens?

Does your computer have any sort of IT-installed software that might be locking down unknown apps?

Thanks,

Gary

Hey Gary,

Yes the AWE Server launches directly by running the executable, and can even launch through Matlab. I still get the error that it was unable to start the AWE_Server.exe message in the Matlab window, and I can't move forward with getting the Designer open. 

I have no reported blockings from my firewall or IT software, I can get them involved to check the handling between Matlab and AWE.

Thanks,
Brad

Hi Brad,

In both of those cases, does AWE Server stay running?  Seems like when you are doing the launch via MATLAB, clearly not, but I just want to try to identify any possible difference between:

a) AWE Server is running but MATLAB/Designer can't detect it

b) AWE Server is not running at all.

If you look at Task Manager, do you have any stray running instances of awe_designer.exe or AWE Server, when you think everything is shut down?

Thanks,

Gary
