Hello,
during license activation, we get the following sporadic error from Aspose.Zip:
System.InvalidOperationException:
Failed to set license. Details: Der Thread wurde abgebrochen.
bei ?.(Object )
bei ?. (? , )
bei ?.()
bei ?. (Boolean )
bei ?.(Object )
bei ?.()
bei ?.(Object , UInt32 )
bei ?. (Boolean )
bei ?. (Boolean )
bei ?.()
bei ?.(Object[] , Type[] , Type[] , Object[] )
bei ?.(Stream , String , Object[] , Type[] , Type[] , Object[] )
We call the license activation from different parallel processes. I created a test application to check if parallel license activation is a problem, but i cannot reproduce this behavior.
Can you help me to find out what leads to this error?
Kind Regards,
Andy
Hello @AStelzner, yes, it seems like a multithreading issue. Please attach your sample, we’ll try to reproduce.
@denis.kudelin FYI.
It’s almost impossible to recreate this, because it’s very complex.
I can’t recreate it for me either, it’s only happening for our customer.
Some of the calls are COM and parallel too.
Are there any known restrictions?

Setting license does not invoke any operation in a separate thread and does not instantiate threads or tasks.
We’ll try to reproduce such error by playing with the license activation in multithreaded environment. Can you roughly explain how your customer uses parallel processes? - Do they use threads or tasks, do async methods involved? - Is their product a web application?
Generally, it unlikely that our licensing code causes the threading exception.
I’ll get back to you when I have the info.
But the exception clearly came from the Aspose.Zip licensing method, see my first post
