Acquisition board not found

[AthiemoneZero]

Hi, I used to run Open-ephys GUI and used it to connect to the acquisition board for biosignal acquisitions. But I met this problem when I recently reinstall GUI in another PC.

I found that during this installation the program called a error:

I'm not sure if the problem of connection might be raised from the C++ library.

Can you try manually installing the 2015-2022 redistributable from this link? https://learn.microsoft.com/en-us/cpp/windows/latest-supported-vc-redist?view=msvc-170#visual-studio-2015-2017-2019-and-2022

If this is not installed, the GUI should not be able to launch. But it's possible that an improper installation is related to the acquisition board not being detected.

Also, be sure that you're using the correct plugin for your board (either "Acquisition Board" for devices with an Opal Kelly FPGA, or "OE FPGA Acquisition Board" for devices with a custom FPGA purchased in Nov. 2022 or later).

Hi, thanks for your kindly reply. I tried checking the installation of VS2019 before as well as the Opal Kelly FPGA package, but nothing got changed. According to the abovementioned advice, I manually downloaded the redistribution package (X64) and opened it. This program advises me to repair VS and restart Windows (seems I have successfully installed VS before). But the problem is still here.

Despite these, I finally transferred the operation system (also Win10) to it from another PC I have on which openehpys works well. This time everything seems good and I smoothly open the openephys windows.

Though, I still have no idea what the problem is : (

Can you provide some details about the two PCs (manufacturer, processor, memory, etc.)?

[AthiemoneZero]

Yes.

This on is the system information of the PC with problem in finding acquisition board: (but now I copy the whole operation system from another one):

This is the other one that works well:

Hope this can provide available information for solving this problem

Thanks for this info! Did you happen to try all of the USB ports on the HP Microtower, and did it fail to detect the acquisition board on all of them?

[AthiemoneZero]

Hi, I did try all of the USB ports and also I checked that all I tried are USB3.0 port. But they cannot work as well. Still, I even tried using a PCIe to USB 3.0 high-speed expansion card, but I cannot fix it. After I reinstall OS, all the original port in the HP can work. Really strange, right? I guess this problem might have some relations with the AMD core, as my laptop with AMD core also has the same question in detecting acquisition board while opening open-ephys. However, I don't go further to study it. Anyway, thanks for your following and patience on this issue!
