Hi

I am approaching the point of making my product commercial and the unkown publisher messages etc when running the installer are off putting and look unproffesional.

What can be done about this?

Is it something we can do or does Megunolink and builder need to be changed?

It's a tricky one. You actually need to sign the installer yourself so that windows trusts it.

Code signing certificates became very expensive and complicated in the last couple of years too, requiring distribution of certificates on security tokens. We started using Microsoft's code signing service (https://azure.microsoft.com/en-us/produ ... ed-signing) this year. Essentially, the private keys sit in Azure and you use the signing tool to request Azure sign the installer. MegunoLink's installer is signed this way. Each certificate expires in a day or so (a new one is issued automatically), but it appears the certificate only needs to be valid when the installer is actually signed and timestamp.
