Can't activate clean install after upgrading from Win7
Hello,
I'm trying to activate my Windows 10 with the key I got from the upgrade I did with Windows 7.
I used a virtual machine for the upgrade and it did activated but after a clean install it just saying I can't activate it.
The actions I did:
1. Install win7 on virtual machine.
2. Activate it with a key and update.
3. Installing the upgrade with the iso file inside the os.
4. Installed win10 and it was activate.
5. Got the product key with KeyFinder.
6. Format the HDD and installed clean Windows 10 with the ISO file.
7. Tried to activate the clean os with the key I got with KeyFinder.
8. Got an error that the key cannot be activated (0xC004C003)
What can I do to activate it?
