When you download the Update Manager bootstrapper and then install Update Manager from Empower, the Update Manager components are verified using SHA256 checksums.

During component download, activity might appear at times to stop completely. The cause might be that your virus scanner is scanning the components. Add the Update Manager installation directory to the virus scanner's exclusion list. If you do not have such a list, disable your anti-virus software while using Update Manager.

If your network interferes with the component download, you might have problems connecting to Empower or see error messages about corrupted Zip files. Try the following:

Most download issues are caused by interference from a security appliance such as a virus scanner. Ask your network administrator whether he can make an adjustment to allow the download to work properly. Also check whether a proxy must be used to download files properly in Update Manager. Ask the network administrator to check the security settings for your proxy or firewall; they might be incompatible with Update Manager. If so, ask your IT department for temporary access to a port outside the firewall to download the components.

Run Update Manager again, but this time select the Use SSL to connect to the Software AG Update Manager Server option on the Proxy panel. Using SSL may allow installation to continue despite security appliances because the streams will be encrypted; the encrypted streams should not trigger anti-virus, anti-malware, or other scanners. Also test whether your network is handling SSL traffic properly; public websites are available to help with this diagnoses. The verbose log will give you a great deal of troubleshooting information, but even if you cannot spot the problem, you will need to provide the verbose log to Software AG Global Support.

If you have access to another network, try running the same installation on the other network. If the installation succeeds, create an installation image to use on machines in the network that is experiencing problems.

If you are still having trouble after trying these options, contact Software AG Global Support for help. If the issue cannot be resolved after exploring all possibilities, or if you need an installation image urgently, Software AG Global Support can contact Software AG Logistics to provide Update Manager on a DVD or through a private FTP site.
