Onflow is a company that asked me to include their installer program with mine on a cash per download agreement. It needs to contact the internet when it is installed so that they can include the download in their counting. The zipped version does not include the plug-in. If there is no package for your language, then just use the language editor in the options window to create one. I will include it in the next version, so other people will be able to use it.
Most people are able to download the file without any problems.
The maker of the installation software has told me that the corrupted file message usually means you have a virus on your machine, or that you are out of disk space. Please scan your computer for viruses, free some disk space, or download the zipped version above. Reliability is my highest priority. If the alarm doesn't work properly, please tell me. Use the mail forum , or email me.
