Very frustrating searching the Internet and can't find an answer either. Where is a good source for an .exe for RDWorks v8? Downloading from this site says it's an .exe download, but actually is the .rar file all over again sent with the laser.
The executable/installation file is actually the RAR archive, but you'll have to extract it first. To do this, install WinRar or 7Zip, then right click the archivbe and choose Extract to. Select a folder on your desktop or similar and that's it. The file will be placed in that directory.
You can download the applications from the links posted below:
Another online solution is to use your google drive and open with cloud converter. you can then save it as a zip.
