    Hi: I've been trying to install my venerable, but still working well, ST4000 XCM onto a windows 10 laptop. The camera works fine on my Windows 11 desktop and on my ancient Windows XP laptop. I've installed from the original disk and run the 64 bit driver checker, updated with the latest and, when I try to start CCDOPS, I get a "No SBGUDrv.DLL error." That file is present in Window System32. A version with no caps in the name is present in Window System. I've tried everything that I can think of. Any advice?

    Thanks,
    Alan

    Hi Alan, you can retire that original disk. It's probably from 10-20 years ago.

    1. Disconnect and power off the camera.
    2. Uninstall CCDOps.
    3. Remove the Drivers using the SBIG Driver Checker.
    4. Uninstall the SBIG Driver Checker.

    Everything you need is here:
    https://diffractionlimited.com/legacy-product-support/

    5. Download and install the current SBIG Driver Checker:
    https://cdn.diffractionlimited.com/downloads/SetupDriverChecker64.exe

    6. Run the driver checker, and Update the drivers.
    7. Connect the camera and power it on.
    8. Give it a couple minutes for Windows to find it.
    9. Check Windows Device Manager, USB devices, for an SBIG Camera.
    If it's not there, then you have a bad cable, USB port, or operating system corruption - let us know, as I can offer some suggestions.
    If it's there, move on to the next step.

    10. Download and install the final version of CCDOps 5.66:
    https://cdn.diffractionlimited.com/downloads/InstOps.exe

    11. Fix Windows Power Management / USB Selective suspend per this article:
    https://forum.diffractionlimited.co...connects-turn-off-usb-selective-suspend.7848/
    You should be good to go.

    If this is a FRESH INSTALL of Windows 10, then:
    Run Windows Update multiple times until it is completely updated. Reboot after each update.

    Next, you need to install the Microsoft Runtime 2015:
    https://forum.diffractionlimited.co...talling-microsoft-visual-studio-runtime.9001/

    If this is a corrupted Windows system or unreliable, see here:

    Colin: After following your instructions carefully -- preceded by several iterations of haphazardly following them -- I found that I was missing the X86 version of C++. After remedying that, I am able to connect to the camera using both CCDOps and SGP. However, in both cases, the download is glacially slow and the Dark image has some streaks. Everything works fine on both my Windows 11 desktop and my antiquated XP machine, so I'm confident that it's not the camera or cable. Have you any further wisdom?
    Thanks,
    Alan

    Keep in mind the ST-series cameras were from perhaps 15 years ago, when USB 1.1 was the connection, and the CCDs can't be read out very fast.
    A full frame image will take about 10 seconds to download.
    There is no frame buffer memory in the camera, so it downloads each row, one at a time, and if there is any interruption in communication, you may get streaks or other row-based artifacts.

    Quit your programs.
    Launch SBIG Driver Checker.
    Click [Debug Log]
    Verify that nothing is selected - click [Clear All]
    Click [OK]
    If anything was selected, the driver checker may have been writing a log, slowing things down.

    If that's not it, I'd suspect cables, hubs, or USB ports, or multiple devices sharing the USB bus.
    Plug the camera directly into the back of the PC with a short cable, and try again.
    Do not have multiple devices like a mount, focuser, rotator, USB-to-RS232 adapter, dome controller, mouse, keyboard sharing the USB bus that the camera is on.
    You can find a utility called USBView or similar that will show you what all is on the same USB bus.
    Or in Device Manager, find the SBIG Camera, then View Devices by Connection, and it will show you the hierarchy of devices.
    You want the camera to be on its own bus, with the fewest levels.
