digital sign gone

Hi, I have something strange. With Setupbuilder I made an 'update.exe' - it
is dig. signed. I put this on my website.
In my Clarion app I check if this is newer then the current and when newer I
download it (NT FTP). When I try to run it Windows (10) refuses to run it.
When I look at the properties: no digital sign anymore

When I download it by hand all is fine. Any ideas ?

Piet,

so before you upload, the signature is there. Then you download from your
site and the signature is gone?

Just a little test: check the CRC-32 before you upload. Then download the
'update.exe' from your server and check the CRC-32 again. The CRC-32 value
does not match, correct?
