Hi, I have downloaded and installed a trial version of Parallels Desktop for Mac 13 on an iMac running OSX 10.11.6. Install went well, but when I try to use Parallels to open/convert my existing Fusion VM, the Installation Assistant starts and says it is converting my WinXP guest, but does nothing. In over an hour now, the progress bar shows zero progress and the iMac Utility shows Parallels is using almost zero cpu or other resources. Any suggestions about what I can try next, gratefully received. Brian.
