Click “Download” above. The file lives on GitHub Releases, which that button points to. You get FormDD-Setup-x.y.z.exe. Do not download it from anywhere else.
Install on Windows
Download & install FormDD
During install, Windows shows a blue “Unknown publisher” warning — this is normal for apps from a small developer, not a virus. Follow the steps below to get past it safely.
Double-click it. If your browser warns “this file isn’t commonly downloaded”, choose Keep.
This is the blue SmartScreen screen, not an admin-permission prompt. Click More info, then Run anyway — the button only appears after you click More info.
Click Next through the wizard. Setup installs into your user folder. No administrator rights are needed — do not “Run as administrator”.
Launch it from the desktop icon. You can try the sample forms right away — no key needed.
Why does Windows say “Unknown publisher”?
Windows flags any app that doesn’t yet carry a code-signing certificate it recognizes. FormDD is built by a small team and that certificate is still being arranged — so the warning shows as a precaution. It does not mean the file has a virus or was tampered with.
To be sure before installing: (1) only download from the official link, (2) verify the file’s SHA256 (below), (3) scan with Windows Defender or upload it to virustotal.com.
For IT — verify the file with SHA256
Every release ships a SHA256SUMS.txt on its Release page. Open PowerShell and run:
Get-FileHash .\FormDD-Setup-x.y.z.exe -Algorithm SHA256
Compare the value with the matching line in SHA256SUMS.txt. If they match, the file is intact and untampered.
Open Windows Security → Protection history → pick the FormDD item → Allow / Restore.
The installer does not need administrator rights. If the file vanished, restore it from Defender (above) and download again from the button on this page. Do not run Setup as administrator — it would install into a different folder from your saved work.
Settings → Apps → search “FormDD” → Uninstall. Your saved work stays until you delete it yourself.
