Our install has been working fine at customer locations, but we ran across a problem yesterday on a new installation. When attempting the install, we got the following errors:

Here are the error/warningn messages:
- Warning: Unsigned script file (installer could continue after warning. Never saw this otherwise)
- Error: 1621 - Unable to verify signature of file isscript.msi
- Error: 1607 - Unable to iinstall Install Shield scripting runtime.

The installer suspects it could be a permissions thing (I don't know what accnt the user logged in as), but I have been unable to find any info supporting that. I did find information that you could have this problem if wintrust.dll isn't on the machine and we are still waiting to hear from the customer to verify that fact.

Is this problem familiar to anyone? Is there something we can change in our install to avoid this problem?

thanks

To avoid corruption or tampering the iscript.msi file is digitally signed. It looks like either the signature is missing, or the file has been modified, or somthing on the target system is missing (wintrust.dll) that is required to verify the signature. I believe this check is performed by InstallShield's setup.exe. As a workaround don't use setup.exe. Instead double click isscript.msi.
