Failed to unlock account *account number* (no key for given address or file)

Hi guys,

I created an ethereum address using geth and chocolatey some years ago. My PC has since been wiped due to some software problems, recently I decided to update my account however. I’ve reinstalled geth and the relevant software as per the installation instructions on GoEthereum.

When I use the commandline:

geth account update (account number)

I am prompted to insert my password. It seems as though nothing registers when I type, and when I hit enter, I am given this line:

Fatal: Failed to unlock account 0xe20fd4b011f41a1605bf8e41876bd14340bf174b (no key for given address or file)

Any ideas please? Would really appreciate some help as I’m barely understanding what I’m doing :stuck_out_tongue:
