I installed the Windows 10 Preview Operating System (Windows 10 Pro Technical Preview Build Evaluation Copy 10049) and it does not work with Proclaim. Will you be making Proclaim compatible and when?
I tried to reproduce this issue in house and I could not; Proclaim is running fine on the machine I have Windows 10 installed on. What type of error message are you receiving? Could you post your logs?
I am running build 10041 and proclaim will not run on it. I have tried running it in administrator mode and in compatibility mode. It ran before the latest update to proclaim.
What happens when you try to run Proclaim?
