Wallet 0.1.3 Windows EXE
Windows 7 x64 Home Premium Service Pack 1 with all current updates
AMD FX-8150 8 Core CPU
ASUS Crosshair V Formula Thunderbolt Motherboard with UEFI BIOS 1702 or maybe 1703 (whichever was newest last month)
16 GB Corsair Vengeance DDR3 RAM

I removed the previous wallet, backed up my wallet.dat file saved my .conf and peers.dat then deleted the whole Syscoin folder.
Ran the new wallet as administrator with none of the prior files restored. Ran fine and sync'd the first time.
Restored ONLY wallet.dat and ran it as administrator again, got the error that means corrupt wallet.dat - reran it as administrator with the -salvagewallet and that worked that time.
Exited the wallet software, waited a few minutes, then tried to run it as administrator again - showed splash screen for a moment and said verifying blockchain, then vanished except the system tray icon.
Opened my task manager and ended the process tree.
Ran in as administrator again - started to load, no GUI but back in the system tray.
Saved wallet.dat and nuked the Syscoin folder.
Created Syscoin folder and copied my wallet.dat to it.
Ran it as administrator again - it synced fine and wallet was ok.
Closed it and reran as administrator - started to load, no GUI but back in the system tray.

For me, the wallet has the same problem where it can be run one time but will fail if it is run again, unless the Syscoin folder is nuked.
I did not try it on any of my other machines or Windows versions.

Perhaps there's some commonality among those of us with the GUI problem. Might be CPU brand, CPU number of cores, Windows Premium instead of regular, installed version of service pack, UEFI BIOS, or who knows...

So, maybe others with a malfunctioning Windows EXE version of the wallet can include a bit of basic system information, to see if the issue lies in the hardware config or the installed Windows particulars or whatever. It could be a dead end, but no harm trying.

Run it with -reindex for now and it should work.
