Question content

I am trying to call the tpmisready function from the tpmcoreprovisioning.dll included on windows. I don't notice anything obviously wrong with the code, but the error is thrown regardless.

This is what I have:

package windows

import (
    "errors"
    "log"
    "syscall"
    "unsafe"
)

var (
    TPMDLL   = syscall.NewLazyDLL("TpmCoreProvisioning.dll")
    TpmReady = TPMDLL.NewProc("TpmIsReady")
)

func IsTpmReady() (bool, error) {
    var enabled byte
    ptr := (uintptr)(unsafe.Pointer(&enabled))
    _, _, err := TpmReady.Call(ptr)
    if errors.Is(err, syscall.Errno(0)) {
        return enabled == 1, nil
    }
    if DEBUG {
        log.Printf("IsTpmReady: %v", err)
    }
    return false, err
}

Am I using the wrong thing, or not freeing resources?

Solution

Although this is not really my area of ​​expertise as @Eelco mentioned most of the time it should have something to do with your antivirus. You can continue through this checklist:

1. Disable any antivirus software you are running, including Windows Defender
2. Run it as administrator (I'm assuming you've already tried this)
3. Check that you are using the latest version of Windows

If it still doesn't work, try performing a clean boot

1. Press windows R and enter "msconfig"

2. It should open the "System Configuration" from which you have to navigate to the "Services Tab" and check the "Hide all Microsoft Services box" and then press the Disable button

3. Navigate to the Startup tab and disable all programs in the same way and click Apply after closing the Task Manager window inside the tab

4. Continue to restart the computer and run the program again

If it still doesn't work, maybe restart your computer in safe mode (using networking as it's easier to search for something if you need to) and try again.

If it still doesn't work: At this point I don't know what else might work. But you can try running it on another computer and see if the error persists. You can reset the machine, but this can be inconvenient. Check if you have any programs that may be conflicting or extending.
