Verify the file before running it. In PowerShell, from the folder you saved it in:

Get-FileHash .\ConstructionPaper.exe -Algorithm SHA256

The Hash it prints should match the line above, ignoring case. If it does not, delete the file and download it again.

Windows SmartScreen will warn about an unrecognized publisher — the executable is not code-signed, and the hash above is how you verify it instead.

A license key is required. Construction Paper will not open without one. https://cxpaper.com/license/
