The Windows Cato Client installation fails and shows the following screen:

Solution

1. Open the Windows Installer log and check for the error code.
2. If the error code displayed is "1603", this indicates that there was a general Windows installer issue that could be related to permissions.
3. If you are using MSIEXEC for the client installation, do not use the "/j" option. The "/j" option will change the installer to an advertised package. For details on the option, refer to Microsoft MSIEXEC Options.  Refer to Upgrading-Cato-Windows-Client for instructions on how to install/upgrade a client using MSIEXEC. 
4. Further information regarding the 1603 error code is available in this article provided directly by Microsoft.
