I've been dealing with an HDR user who has been unable to make the installer floppys for his HDR. The WinImage extractor would run for a bit, then quit with an error that looked like it was saying that it couldn't further write to the floppy. From the last screen shot he sent me, I noticed that he was running Windows 10, something I don't have. Thinking there might be something funny about Win10, I suggested that rather than running the self-extracting files out of the unZIP utility, that he save them to the desktop and run them from there.
When he did that, it ran the extractor all the way through, though apparently it extracted the installation files to a folder on his computer rather than to the floppy disk. It could be that he had the "Extract Files" box checked and didn't notice that a previously blank box now pointed to a folder.
But it got me wondering . . . with every edition of Windows, Microsoft tries harder and harder to keep you from running a program that it thinks might corrupt something. So my last suggestion (and I haven't heard back with results yet) was to right-click on the EXE file and click "Run as administrator."
So, assuming that everyone using Windows but me is running Win10, is there a trick to running the installation disk builder that users should be reminded of?
