I have carried out the actions described above, unfortunately to no avail.
I still can not update Garmin.
I believe it is being blocked for some reason.
The complete message reads:
Garmin Express could not be installed on this computer. Try Installing again
I'm sorry to say I still get the sme result
Yes it is set as Administrator, Password *****
I have created a new account and signed in with this account but the result is still the same when I try to update Garmin Express
Thank you for your endeavours but I think we are flogging a dead horse here.
I believe I will have to consider a new PC.
Thank you again.
