I have synced. I then click on 'monero-wallet-gui'. I get this message. "The program can't start because |1-2-0.dll is missing from your computer" Please advise.
Regards, nrmis,
I suggest ditching microsoft for linux.
If you do decide to stick with windows, Don't download dlls from seedy download sites or used a cracked OS. Only use microsoft download source or update utility.
A little searching reveals this may be a corrupted or missing Visual C++ Runtime file.
