Hello,

I found the issue, it was a typing errore in the licenseId of the Method.

I apologize for disturbing you unnecessarily.

Sorry, I continue here:
- I used RegisterManagedResourceWithExistenceCheck Method and no exceptions are thrown.
- If I retrieve the serial number "1111111120" and using the example it gives me that the License is a Trial license.
- I tried using the IL DASM tool and the key matches the one used in the source code.

Hello,

I followed every step of the troubleshooting section and:

Hello,

I have a Multipurpose ultimate license for QuickOPC 5.63 version and I'm experiencing issues running executables in a production PC.
I'm using the "RegisterManagedResource" method in my Visual Studio project (development PC) but once I deploy the .exe and try to run it in a production PC it gives me back some errors (attached you can find the screenshot of the error).

The weird behaviour is that if I install the license (on production pc) with the license manager, everything works fine. But of course, I'm using the "RegisterManagedResource" method in the VS project just to avoid installing licenses on production PCs. As I read in your forum: "The main advantage of this method is that it does not require any additional actions during deployment. Also, because the Managed Resource License is the first one in the search order, you have a guarantee that if you properly place a specific valid license key into the managed resource license store, it will be the one actually used - it cannot be changed by License Manager, for example. The disadvantage of this method is that you need to put extra code and data into your application, before building it."

Is it there something that I'm missing?

Thanks.
