I have literally tried two different download managers and at least 12 different download attempts. The results are either a crash at 95% in unpacking or the installer bugging out at around the 45% mark. The consistency suggests a problem with the install detecting something.
I know that there are other strings discussing this issue that mention the download manager. At least one of the strings was resolved by the user actually restoring his system to a prior point rather than using a new download manager.
I have tried cleaning up the registry after the uninstalling the prior install with a registry cleaner. But, I think there may be a possibility that something is left there. I also have a directory from a prior install that I can not get access to or delete.
Thank you for your help.
