Allegro X Capture will not launch again after closing the application

Zhifeng Jin

Dear Cadence Experts,

I frequently run into an issue where Allegro X Capture 25.1 fails to launch again after closing the software. My operating system is Windows 11 25H2, software build is OrCAD Capture 25.1 S050. This problem is not limited to S050; it also existed in previous releases.

I’ve just found the root‑cause of this issue. Sometimes after closing OrCAD Capture, its background process does not actually exit. Since OrCAD Capture does not allow multiple instances to run simultaneously, there is no response when you try to launch the software again. My screenshot shows that the OrCAD Capture process remains active in Windows Task Manager even after I close the application. Why the process keeps running after the GUI is closed will need further investigation by Cadence experts.

    Hi Zhifeng,

    When Capture remains running in the background, what is the CPU and memory utilization of the Capture.exe process.
    Also, how much time it takes for the process to be killed automatically?

    I took these screenshots when I reproduced this issue a moment ago. CPU and memory usage are visible in the images. The background process keeps running; it will auto‑terminate after roughly 10 to 30 minutes. I’ve noticed this problem occurs much more easily if you open many schematic pages and then close the software.

    To correct my earlier observation: the background process never terminates automatically, even after a long period of time. I just reproduced this issue and monitored it for more than an hour; the OrCAD Capture.exe process remained running the entire time.
