Azure Storage Sync Agent Install - Setup Wizard Ended Prematurely

Question

Trying to update the Azure File Sync agent (old version "will expire soon") and it keeps failing. It starts to install then rolls back and says the Wizard ended prematurely. Tried uninstalling the old / current agent first then installing the new version. Same result. Tried to reinstall the old version and now that one won't install. Storage Sync Agent is no longer listed in services. Following is from the install log:

CustomAction RollbackStopStorageSyncFilter returned actual error code 1603 but will be translated to success due to continue marking

Any help would be greatly appreciated. Thanks
