I'm running the latest version of Parallels 9 (9.0.23136) on a 27-inch, mid-2010 iMac, running MacOS X 10.8.5.
Running Win 8 worked just fine, and yesterday, after attending a webinar featuring a Parallels participant, I was assured that upgrading to Win 8.1 would work just fine.
The upgrade process did indeed work, but now, tonight, I'm unable to drag any files onto the Win 8.1 desktop from my Mac desktop.
Others have been having the same problem under Parallels 8, but it's also apparently a problem with Parallels 9. Other threads recommended uninstalling Parallels Tools and then reinstalling them, but there have been reports of numerous problems with that process, including the inability to FIND Parallels Tools to reinstall.
Just now, I double-clicked on the Parallels Shared Folders icon on the Win 8.1 desktop, and got an error message: Windows Can't Access \\psf.
And though Firefox for Windows seems connected to the Internet, my Dropbox folder is NOT updating.
I then clicked on the Parallels menu: Virtual Machine > Reinstall Parallels Tools. (I didn't try to uninstall the Parallels Shared Folders file.) The reinstall seemed to go okay, Windows rebooted, and I logged in again. Although I still get the same error message when I click on the Parallels Shared Folders icon, I'm wondering whether that's something I can access anyway?
Dropbox began updating, so that's a good sign, and when I dragged a Word document from my Mac desktop to the Win desktop, at least I got the + sign, but no document appeared.
UPDATE: I rebooted for the second time, and tried dragging a document into the Windows desktop. Yay! It worked!
I guess I'm pretty much a novice at this!
