I have exactly the same problem - possibly due to a recent Windows 10 update - this really does need an urgent fix by the developers.
I have personally resorted to signing compiled .exe manually. …You will need to download the DigiCert utility from their website. However, this solution does not sign the uninstall package which is created as part of the compiled install .exe - this means the user may get security errors flagged when running this file.
We already have a fix for registered customers.
Start PB, go to Environment Options and enter http://timestamp.sectigo.com
for both timestamp URLs.
If the issue is still not solved, contact us to get a patch.
We were also affected by this error and tracked it down to the timestamp server URL. Unfortunately, we are using the console command-line compiler tool PBCMDCOMPILER, and this does not pick up the URLs I have configured in the GUI. Is there a way to set these as arguments to the compiler?
We are currently running 3.7.1. Could we upgrade to the latest version using the same license?
