Here was another post with the same (well, similiar) problem, I’m assuming they just ran zcashd manually and then started zecwallet but not sure, they don’t specify though they said it worked. The daemon configuration may be preventing it from starting.
The docs but basically says the same thing
But like hanh mentioned, there are other methods too
To run manually
"
NOTE: The following commands assume a default installation using the Windows Installer Method (MSI Install File). If using the ZIP version, the path should be changed to the location of where the files were extracted.
- Close Zecwallet Fullnode.
- Run the following Command (Windows Key + R)
%LOCALAPPDATA%\Programs\zecwallet\resources\bin\win\zcashd.exe -reindex
*You may open ZecWallet FullNode at this time to see any updates or changes.
It will take time to process the changes, but when done, I am not sure if closing ZecWallet Full Node will close zcashd.exe properly. To do this, run the following command:
%LOCALAPPDATA%\Programs\zecwallet\resources\bin\win\zcash-cli.exe stop
"
As you can see it has the -reindex flag so if you dont want to begin immediately (shouldn’t wait too long) then just remove it.
