I have Acer Predator Laptop, i am getting windows Activation error. So i tried retrieving the  product key using the below command which gives me error. 
Does that mean Windows activation key corrupted. I want to reinstall my windows 10.

Thanks for your Patient..I am scratching my head for last 2 days..
As i have mentioned that i am getting Windows Activation Error therefore Product Id not available under System. So i tried to retrieve it using the  command "wmic path SoftwareLicensingService get OA3xOriginalProductKey" but there it is coming as blank as i have attached the screenshot in the previous comment. So is the key got deleted or get corrupt in the motherboard firmware ?

@Pats07pk try this 

1. Open a new Notepad window

2. Copy and paste the following text into the window

Set WshShell = CreateObject("WScript.Shell")
MsgBox ConvertToKey(WshShell.RegRead("HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\DigitalProductId"))

Function ConvertToKey(Key)
Const KeyOffset = 52
i = 28
Chars = "BCDFGHJKMPQRTVWXY2346789"
Do
Cur = 0
x = 14
Do
Cur = Cur * 256
Cur = Key(x + KeyOffset) + Cur
Key(x + KeyOffset) = (Cur \ 24) And 255
Cur = Cur Mod 24
x = x -1
Loop While x >= 0
i = i -1
KeyOutput = Mid(Chars, Cur + 1, 1) & KeyOutput
If (((29 - i) Mod 6) = 0) And (i <> -1) Then
i = i -1
KeyOutput = "-" & KeyOutput
End If
Loop While i >= 0
ConvertToKey = KeyOutput
End Function

3. Click File > Save As and save the file to your desktop as productkey.vbs. It's important to include the .vbs extension because this is a Windows Scripting Host file.

4. Close Notepad and double-click the file. Wait a few seconds, and then you will be presented with a popup displaying your product key:

To better understand the issue that you're presenting Pats07pk, can you share a screenshot of the error (s),  i have a couple of questions:

When did you purchase this unit?
Have you re-installed the O.S. or have you change the factory default O.S. for this unit?
Any recent changes/updates recently that you can recall?

Thanks in advance,
