Windows says the publisher is not recognised

Short answer: Litesum's installers are not yet code-signed, so Windows shows its "unknown publisher" warning. A certificate is being obtained. Until then, check the file you downloaded against the SHA-256 published beside it on the download page.

Why it appears

Windows trusts installers signed with a certificate it recognises. Litesum's certificate is being obtained as part of forming the company. Even after signing, a new certificate can still trigger the warning for a while.

Checking a download

1. On the download page, copy the SHA-256 shown beside the file.
2. In PowerShell, run:

Get-FileHash .\the-file-you-downloaded.exe -Algorithm SHA256

3. Compare the result with the published value. If they match, the file is the one Litesum published. If they differ, delete it and download again.
