MSI (s) (88:4C) [10:52:29:923]: Product: www.yyy.xxx.zzz. -- Error 1722. There is a problem with this Windows Installer package. A program run as part of the setup did not finish as expected. Contact your support personnel or package vendor. Action DeCryptoWebConfig, location: C:\Windows\Installer\MSI34C0.tmp, command: -dc "C:\Program Files\xxx\xxx.yyy.zzz\web.config"
Release : 8.6
Component : CA Gen Build Tool
The server admins finally determined what the issue was. Someone had modified the web.config file that is used on the servers and had put in lines which weren’t XML compliant so apparently when the utility tried to read or update the file, it was failing.
Remove the non-XML compliant lines in the web.config file.
