Zcash for Windows Release Candidate

Yes you read that subject line correctly! My release candidate for command line Windows Zcash (requires 64 bit Windows 7 or newer) is at:


You need to manually download the proving keys into:
which is normally C:\Users\YOUR-USERNAME\AppData\Roaming\ZcashParams\

They are on my mirror of them on the fast Amazon CloudFront CDN at:
https://zcash.dl.mercerweiss.com/sprout-proving.key and

And create a zcash.conf file in:
%AppData%\Zcash\ which is normally at

For what to put in your zcash.conf, its the same as for linux in the User Guide. If you want to see the fun splash screen output, you need to launch zcashd.exe usering Powershell with showmetrics activated in your zcash.conf or on the command line, like so:
.\zcashd.exe -showmetrics=1 -daemon=0

HOWEVER, use cmd.exe, not Powershell, for sending transactions with zcash-cli.exe, or the quoting is even more esoteric than normal! If you use cmd.exe it is the same as for linux as shown in the User Guide.

Its been a long slog working on this since October of last year with input and help from lots of people in the Zcash and Zclassic communities along the way, but we’re finally running on Windows. All-in-one installer with GUI wallet coming soon!

And we’re STILL short on rent, which is due today! I do NOT have a day job, and just 5 ZEC (or equivalent in btc or $$$) will cover what I’m short, donation addresses are at:

Yup, gonna work on the all-in-one installer that bundles Windows zcash, the version of the SwingUIWallet by @vaklinov that he’s tweaked for Windows, the jvm for the GUI, and downloads the proving keys in the GUI, just like I do in zcash4mac

It is a bit techy to launch but nice work!! Donating to you now


Thanks! GUI version coming soon and a longer write-up with screenshots for the command line one later today


Many thanks to @anon47418038 for providing us a ZCash node for Windows. Meanwhile the ZCash Desktop GUI Wallet is also ready and works on Windows:

Here is a quick install procedure for the GUI:

  1. Install the ZCash node on Windows as described at the beginning of this thread,
  2. Install JDK 8 for Windows - e.g. use this good tutorial
  3. Use the latest release of the ZCash Desktop GUI Wallet - download the ZCashSwingWalletUI.jar and place it in the same directory as zcashd.exe and zcash-cli.exe
  4. Double click on the JAR to start it or use a Windows command: java -jar ZCashSwingWalletUI.jar

A more detailed installation procedure will be documented later tonight on the GitHub site of the ZCash Desktop GUI Wallet.


Sometime next week I’ll have an installer that bundles all that together, too
