    I try to use an old SBIG ST7E camera (with a parallel port) on a Windows 7 32 bits desktop computer with a parallel card plugged into a PCI port. (The camera works fine with XP and Vista laptops with an express parallel card.)

    SBIGDriverChecker says “Error opening service manager” and “sbigudrv.sys … yes*2”. However, if I run it as Administrator, it works ok.

    But MaximDL says “Could not initialise camera (1)” . I would be grateful for any suggestion…

    Unfortunately that is not a supported configuration. Microsoft discontinued support for ISA-style parallel port addresses after XP.

    For a time there were cards available that used the processor's protected mode to redirect I/O operations, but it's been a decade since I've encountered one.

    Windows security prevents user mode access to hardware devices. You might do some googling on that issue.
