it's ok. problem in decimal numbers of OS locale
when wallet sync to 100% this error disappear
It does not start sync at all.
Same probblem here.. I've installed it step by step.
Well I had the same issue, not synchronizing at all untill I decided to let the client open and see what happens. It started sync after 1 h probably because many people are all trying at the same time synchronizing their Zclassic wallet. So it might start if you wait longer.
EDIT: Do not forget to start zcashhd.exe before ZClassicSwingWalletGUI.jar
