Who can explain why after the transformation AcroRdrDC.exe and AcroRdrDCUpd. MSP is the Digital Signature lost in AcroRead. MSI?
We encountered such a problem after transforming these files and customizing them via Acrobat Customization Wizard DC, Symantec triggers during installation, and quarantines the file.
On the first screenshot after unpacking AcroRdrDC2100120140_en_US.exe -nos_o " d:\TempAdobeInstallFiles" - nos_ne AcroRead. MSI has a digital signature but after the patch AcroRdrDCUpd2100120140. MSP-AcroRead.msi loses the digital signature, screenshot two.

You are creating a new MSI and it isn't signed? I would expect that, because it was not the unmodified file signed by Adobe. That's really the point of the signature system. Maybe I missed something.

I do not create a new msi, I patch the old one to the current version as recommended by Adobe, and after the patch, the original msi becomes unsigned.
