    I have the same problem.
    When I start Parallels 6 and try to switch to Coherence, I get a message to contact the customer support. I tried it but the support is the worst support I have ever seen.

    So if anybody has an idea how to repair it, please post it.

    Thanks for your help.

    I use it on an iMac27. On my MBP it is working. Same configuration on both machines.

    Problem solved

    Hey,

    I solved my problem. The Coherence Mode is working again.
    The Problem was a Programm called Maxi Vista. It is used for the ipad. With that program you can use your iPad as a second monitor via Wifi. When I deactivate the driver in the System it works. ;-)

    I hope I could help you!

    Ditto for "Air Display"

    I had a similar problem to what was described but in my case the conflict was with the Avatron's "Air Display" app (to allow using iPhone or iPad as a secondary display). The earlier version had not been a problem, but I had just installed version 1.2 this morning before finding the problem in coherence mode. As soon as I uninstalled Air Display (using their uninstaller program) including the required re-boot, Coherence mode was back and working fine.

    Hopefully this conflict can be resolved in future releases as I like both Parallels and Air Display.

    Coherence not working

    I have a different but similar issue with coherence. It was working properly prior to today. However, when I started XP today it refuses to stay in coherence. Anytime I try to open a Windows program, click the task bar, etc., it pops into windowed mode automatically. Help?

    Had some problem; got it fixed

    My coherence mode worked perfectly until this morning. I worked on the problem all morning, trying to figure out what was going on. Found that you all had a similar problem, but couldn't follow any of the ideas presented here to fix it. An additional problem I had was that I could not log into Windows to even try some of the solutions.

    Eventually I clicked on the "Device" item of the Parallels menu bar, chose "Keyboard", clicked on "alt+control+delete, and restarted the virtual machine. Voila! It works again.

    Not sure exactly what I did that did the trick, but thankful to have my machine back!

    This has recently started happening on my iMac. Snow Leopard and all latest updates; Parallels and all latest updates. Was fine until recently

    Hmm
    first coherence worked ok. I had to reinstall another program so I reinstalled Parallels. To my surprise the coherence was gray!!
    What did I do? I tried 'alt+control+delete' (advice from this forum). No.. it did not work.
    I then checked and somewhere (I am sorry, but I just clicked away, he-he) At some point I clicked 'control+command+enter' since this should toggle the coherence. Did not work. Then i reinstalled Parallels Tools... and guess what! Coherence is back in.

    good luck

    same thing here. Re-installing the Parallels tools would help but 1 day later, the problem would be back. So I reinstall the tools, it works again, next day it's broken again.

    There have been no changes in my setup other than that I activated the TimeMachine backup recently. Is it possible that these effects coincide?

    Thanks,
    J

    have you tried toggle the coherence? Ctrl+Cmd+Return. You find the shortcuts in the preferences under Keyboard & Mouse.

    regards

    toggle Coherence: Of course, that's when it fails ;)

    I get a dialog box saying that there was an error switching to Coherence. In parallels.log I get the following output:

    FWIW: completely uninstalling, rebooting, re-installing Parallels helped. Thanks for the support, support.

    ...and the problem is back. there were no operational changes to the VM (win7 ultimate/x64) other than the (automated) snapshot taking and deleting. re-installing tools helped once more. the log file message is the same as above. is anyone from parallels monitoring this? I think that the need to re-install the tools every so often constitutes a bug that ought to be fixed.

    thanks for confirming the issue. I'm still hoping that someone from Parallels would chime in and provide some help for this annoying issue.

    And the problem is back with P7

    ... this time with P7. Find the log output snippet attached.

    The relevant line is:
    02-29 17:14:03.594 F /gui:288:207/ Subtask 1 [InitiateSwitch] completed with RC = 80000009 [PRL_ERR_FAILURE]
    02-29 17:14:03.606 F /gui:288:207/ Finishing task SwitchVmDesktopToCoherence <0x13331fdc0> with RC = 80000009 [PRL_ERR_FAILURE]

    Please help. It's been > 1 year and this problem keeps reoccuring across major versions.

    Thanks!
