Error 0x8004317

Hello
 
After installation of SmartFTP client 8.0.2234.0
SmartFTP starts with Licens error 0x80043107  
The activation  was successful
 
 
 

The "DigiCert Assured ID Root Ca" and "DigiCert SHA2 Assured ID Code Signing CA" certificat has been installed in the 'Trusted Root Certification Authorities'
And SmartFTP has been reinstalled, and vi get the same error

- Go to the File Explorer
- Go to %ProgramFiles%\SmartFTP Client
- Right-click sfFTPLib.dll
- Properties
- Go to the Digital Signatures tab
- Select the signature
- Click on Details
- If it doesn't say "This digital signature is okay" then there is something wrong

It's not OK it says "One of the countersignatures is notvalid. the file may have been altered"

Certificates are missing or there is something else broken with your system.

The "DigiCert Assured ID Root Ca" and "DigiCert SHA2 Assured ID Code Signing CA" certificat is installed in the 'Trusted Root Certification Authorities' is that the right place ?
What makes this error occure ?
