I was able to work around the issue by viewing Parallels' Knowledge Base article #114449 at http://kb.parallels.com/en/114449
which is entitled "Parallels Desktop 7 for Mac does not start after upgrade to OS X Mountain Lion" and discusses the fact that users needed to get an updated version of Desktop 7 to run under ML, and provided a clickable link. I downloaded and installed ParallelsDesktop-7.0.15107.796624.dmg, and it brought up my Windows 7 Home Premium installation very nicely. I tweaked a couple of parameters (i.e., pointed it to the USB/Serial adapter), rebooted Windows, and then check its settings. I then tested it by first bringing up the Elecraft K3 Utility, discovering in the process that the new K3 firmware had been released. That was successful as far as I can tell - I haven't explored all of the firmware changes/features yet, but the radio still works. I then brought up Ham Radio DeLuxe, adjusted it to point to the "new" COM port and the USB Audio port, and it appears to work fine. Finally, I did the same with RMS Express and tested it with a WINMOR connection, and it's fine. I don't know if there is a later build of 7.0 out there, nor do I particularly care at this point. I can only hope that further investigation will glean what updates within the Parallels 7 release stream are available, what their designations are, and whether I can selectively update without having to be nagged about migrating to Parallels 8. Bottom line appears to be that users of Windows 7 should NOT migrate to Parallels 8 unless/until they are actually going to immediately migrate to Windows 8 as well. Obviously, some extensive research of the vendor documentation, and full backups of the current working environment, will be needed. My thanks to everyone with whom I've exchanged e-mail both on and off the list about this issue. ________________________________ From: Charles Johnson <cbjk4...@gmail.com> To: Bayard Coolidge <n...@yahoo.com> Cc: Mike Weir <ve3...@hotmail.com>; "elecraft@mailman.qth.net" <elecraft@mailman.qth.net> Sent: Thursday, November 29, 2012 1:00 PM Subject: Re: [Elecraft] Your thoughts on running SDR on a Mac Another idea: I am a registered Apple developer and was a beta tester for Parallels 8. If you are NOT running Windows 8, then Parallels 7 is the virtual platform of choice. It is still available from retailers at substantial discounts to version 8. Almost all of the changes incorporated into Parallels 8 were because of Windows 8 compatibility. Version 7 of Parallels is much more stable, and runs Win XP, Vista & 7 very nicely on most any Mac. 73, Charlie, K4ZRJ On Nov 29, 2012, at 8:34 AM, Bayard Coolidge <n...@yahoo.com> wrote: > I know nothing about SDR, and I own a K3, not a KX3. > > But I do have a 27 inch iMac running Mountain Lion, with Parallels 8 and > Windows 7 64bit Home Premium installed. > > It was working beautifully with RMS Express, HRD, and the Elecraft utilities, > etc. > ...until yesterday (or late Tuesday), when I swallowed the latest update to > Parallels > (build 8.0.18345), which has a bug in it that prevents Windows 7 from being > able > to "see" the USB/Serial FTDI-based cables/chips properly and messes up the > drivers. > The issue has been raised to Parallels support and a fix is in the works, I > think.
