I searched a lot in the forum and on the Internet but doesn’t seem to understand a few things.
In short - I started mining in late 2017 and stopped at the beginning of 2018, using the zcash4win desktop wallet and the zcash.flypool.org pool. Then I sold most of the rig components and only recently decided to connect the rig again and transfer what I already mined. I found out that zcash4win is not supported anymore and ZECwallet is its successor. However, I tried the latest versions of Lite and Fullnode but with no success. Than, I saw that the only thing I need is the wallet.dat file, copied it and pasted it on another PC, in folder CurrentUsers/AppData/Roaming/Zcash. I installed the FullNode version of ZECwallet and for nearly two days of syncing, the progress is only 5%. What is more bothering is that my balance is currently zero. I can see the outgoing transactions that were made from the wallet, so the wallet.dat file is surely recognizable but I’m wondering why the balance is zero and if the whole 100% should be synced before anything appears on it. I’m also wondering if the old miner should be active during this syncing or not. The last thing I’m not sure of is whether I can even do this on another PC or this must be done on the original rig.
If anybody could help here, I would much appreciate it.
This is correct, depending on when you made your transaction (blockheight of the tx) your balance will not show up until the node is 100% synced.
Also, when you install ZecWallet Fullnode the first time it created it’s own empty wallet.dat. after it syncs if the funds don’t show, try to replace the wallet.dat with your old one to be sure it wasn’t overwritten, then perform a
-rescan and your funds should show.
Thanks a lot, Shawn! Just to confirm - the " -rescan" should be added at the back of the .exe file, correct?
Are you running via the CLI? I’m not familiar with how things work on Windows (only Linux) but in Linux it’s
So windows should be similar.
Yes, exactly, thanks again. I’ll update after everything has (successfully) finished.
Hey Shawn (or anybody who could also help here) - I took the last rows of the debug file, containing info about my attempt to start ZECWallet on my old rig. Would be able to take a look and maybe point me at a possible action please? I would really like to spare myself the extra days I would have to wait for the sync on the other PC. Thanks!

For ZecWallet on Windows the best advice I can give is to enable fast sync at the initial setup: Using ZecWallet - ZecWallet Docs
Shawn: thanks a lot for your help, I’m updating as promised and logging this here in case a similar case appears.
Zcash4win->ZECWallet - if somebody installs zecwallet on another PC, all you need is your original wallet.dat file. Create a folder in C:/Users/CurrentUser/AppData/Roaming and name it Zcash. Paste the walled.dat file inside. When ZECWallet is first installed, tick the enable fast sync option. The blockchain is chronologically read and depending on when you mined, it will update your balance accordingly (mine started showing up exactly when blocks from end of 2017 were being read - that can be seen in real time in the debig.log file, located in the same Zcash folder). What I found out is that closing and re-opening the ZECWallet app from time to time helped in increasing the read speed (maybe because I’m using the laptop for other stuff and the CPU priority is changed - do this close/re-open just before going to sleep - this will ensure higher reading speed).
I can’t use ZECWallet normally under windows, but I successfully installed and synced the block under debian.
But I don’t know how to import Zcash4win’s backup file correctly
What problem do you have running Zecwallet on Windows?
When I saw this post, I tried Windows again, and the result was still the same.
If you manually interrupt the program while synchronizing the data block, an error will occur after restarting, and you will be prompted to view the log
Without interruption, the data block is synchronized to about 50%, and the same error message will appear
