No this did not help. I'm running Installshield 2018 R2 Version 24 and I just started getting these messages today "The server response was signed by a certificate which is no longer valid. Would you like to temporarily trust it anyway? (Not recommended.)"
I deleted the two CER####.tmp files mentioned in the thread and have tried rerunning Installshield a number of times. I recreates one of them every time but still generates the certificate error message.
How do I get this working?
Same here. I followed the instructions, but when I restart it I still get the warning prompt:
"The server response was signed by a certificate which is no longer valid..."
I too am running IS 2018 R2 V24
Same here. I delete the CER####.tmp file. I am using InstallShield 2019 R2.
Let's hope this forum is monitored by Flexera...
I have the same problem and beginning to regret using Installshield Premium that seems to be getting worst than previous version.
I as well still have the issue after following the instructions above. InstallShield 2018 R2 Version 24
I also have the same error
No this did not help. I'm running Installshield 2019 R3 , I deleted the CER####.tmp file but when I restart it I still get the warning prompt: "The server response was signed by a certificate which is no longer valid..."
I don't own this software.
But the message is "the server response was signed". So try to evaluate the server keystore for timed out certificates. They must have the capabilities for signing software and at least one of them must be replaced. Often there are "chain of trusts" with public parts for root certificates, intermediate certificates and derived personal and specialized application keystores. On windows you get an idea by using "mmc.exe" with certificate-plugin for computer account. You can delete all certificates beyond end of lifetime, they'll never again give usable results.
Anyways, It seems like flexera have a task for support with new certificates.
with kind regards, Juergen
This did not help. Deleted CER####.tmp file from all of the users on our servers, then booted the server. Restarted my InstallShield 2012 ->still get the warning prompt: "The server response was signed by a certificate which is no longer valid...
