Given that your try block wraps several calls which interact with the operating system, with libraries, and with CREO, then there may be several reasons why your connection request fails.

Keep that in mind.

However, when all other possibilities have been addressed, I will share that today we are also discovering that the second argument in the AsyncConnection_Start call, when passed the value null is a cause of our particular connection failure.

When we change that argument to a string path to a user-writable directory, then the attempt to start an asynchronous connection will immediately succeed.

Examples everywhere show that null should be a permissible value but on some systems the argument cannot be null.

Research is underway to understand what causes this.
