I have downloaded the BTC Core on a portable hard drive using my laptop. It's still updating for recent transactions (25% progress). Everything is fine while I run it using the laptop I used to download the Node over the HD, but if I plug it onto my desktop computer, the bicoin-qt.exe does not show up, the icon shows up only as bitcoin-qt only and when I open the file it takes me back to the beginning of the installation. Could someone tell me if there is anything else I should do in order to use the BTC Node in another computer? TIA
