UPDATING WEBSITE X5 V19.4Автор: Kevin A.
I am getting the same or similar problem. X5 tells me there is an update, I tell it to go ahead, and the green bar gets about 50% across the screen on 'installing new files'. I then get "It was not possible to install the files on your computer. Please verify that all programs are closed and restart the update.
I will now try installing from the full installer I have just downloaded.
Like the OP this is my laptop, the desktop worked normally.
