Could you please also clarify if you are able to connect to another Host from this Viewer? If the same issue occurs when connecting to another Host, it might mean that the Viewer configuration file was somehow corrupted or deleted.
If this is the case, please, try the following: 1. Fully exit the Viewer (File -> Exit). 2. Locate the file config_4.xml in the Remote Utilities Viewer %appdata% folder. 3. Remove the config_4.xml file from that folder. This will reset the Viewer settings/options. Your address books won't be affected by this action.
Could you please clarify if you mean that you get 17 MB installation files using the MSI configurator tool? If this is the case, did you consider using the Agent package instead? Its size is only about 12 MB.
But I did not find anything about installing on a portable drive.
Portable Viewer doesn't require installation. If you already downloaded the Portable Viewer to your drive, then you can start working with it right away. Portable Viewer stores all files in a single folder that you can copy onto the portable drive. Here is a related Documentation article that might be helpful: https://www.remoteutilities.com/support/docs/portable-viewer/
Also, I have the viewer on other machines that work on the normal viewer fine.
It means that the config_4.xml file was corrupted and it was causing the issue. I highly recommend that you add the Viewer installation folder and the %appdata%\Remote Utilities Files\ folder to antivirus software exceptions list to avoid future problems in this regard.
