Strange message after new Version 4.0.3844 install

After installing the latest version of Parallels, I got this message when opening my virtual machine:

"Are you sure you want to start the virtual machine?

One or more kernel components loaded on your Mac are for another version of Parallels Desktop. If you start the virtual machine now, it may work incorrectly. To solve this problem, restart your Mac. If the problem persists, reinstall Parallels Desktop."


I did restart . . . same message. I reinstalled (after uninstalling and deleting any Parallels-related files) . . . same message. How do I get rid of this message (and the virtual machine works just fine . . . just want to eliminate the annoying message)?
 
This message means one of kernel components did not update properly for some reason.

We are investigating this issue

I got same message and same results with rebooting. I uninstalled previous version before installing this one. Maybe there is a glitch in the update which causes this?
 
biglar,

Can you post here the output of the "kextstat -l | grep prl" command from your Mac?

Here is mine (I have the same issue).
Indeed there is one kext numbered 3810.
Though to move from 3810 to 3844 I did:
1) Uninstall 3810 using its uninstaller (from its dmg which I kept)
2) Reboot Mac
3) Install 3844 (which tells me to reboot at the end)
4) So reboot Mac

I re-did this twice yet. I think I should get rid of the old kext, then re-install again over it. But how would you recommend me to remove the offending kext ?

Same with me

Installed on 2 computers same message, tried uninstall and reinstall still the same. Must be a bug
 
Olivier,

Thank you. So, there is a kext that is left unremoved after uninstall. While we're trying to reproduce the issue in-house, can you please do the following:

1. Have configuration as yours (3844 installed, one kext of different version).
2. Perform upgrade install (e.g. do not uninstall Parallels Dekstop, but rather install 3844 over your existing 3844 installation)
3. Check if the kext is still 3810. It shouldn't be.

Well things get stranger. To follow your recipe, I started by re-installing 3844, as I did uninstalled it again right before seeing your post. Though I didn't followed the uninstall by a reboot this time. I went straight to re-install 3844 to get to step 1. It installed WITHOUT ASKING FOR REBOOT. I did kextstat -l to check for prl and found NO 3810, as you can see.

So I started the VMs and none warned me.

Conclusion: for the first time in two years I have seen today the Parallels Desktop asking me to **reboot** at the end of the installation (which I did by clicking to accept). I had the kext versioning issue. I tried uninstalling, rebooting, re-installing which asked me again to reboot and which I did. That didn't do it.
Then I uninstalled again, saw your post before I had time to reboot, so DID NOT reboot, and installed again. This time the install DID NOT request a reboot. And all was well.
--> It looks like the installer wanting to reboot (which was a first time for me) was linked to kext not being upgraded.

I'm not sure the above mess will help you fix anything though. :)

Thanks,

Same thing here - I tried uninstalling and rebooting but still had the same issue. Uninstaling and reinstalling without rebooting fixed the problem.
 
We have reproduced the issue in-house.

We are now looking for the best workaround possible. I'll post update to this thread a bit later.
 
Just for reference, I upgraded from 4.0.3810.351321 using the installer without rebooting aterwards and my kexts were all 4.0 3844.408728, the difference is I didn't load Parallels before upgrading since the previous reboot.
 
Specimen,

Have you upgraded using "install new build over old one" or "uninstall old build - install new one" strategy?
 
I installed over the old one (no uninstall).

(I reiterate that my kexts are all fine and Parallels is working, I'm just posting for reference of what works).
 
How to fix the issue

The issue is caused by kext mismatch after upgrade using "uninstall-install" strategy is performed. Old prl_netbridge kext is left on the system and loads before the build 3844 kext is loaded. In fact, the issue does not cause any negative impact on Parallels Desktop operation, it will work just fine. But the message itself is rather annoying as it appears each time a VM is started.

The issue appears only
- if you had upgraded to build 3844 using "uninstall old build - install new one" strategy, using Uninstaller application from build 3844 to delete older build

The issue will not appear in any of the following cases
- you upgraded using "install new build over old one" strategy
- you upgraded using automatic updater
- you deleted old build using old build's native uninstaller

If you have the issue on your Mac, the following solutions are possible

Solution (recommended):
- download the latest build with this issue fixed,
- use Uninstall application available on the just downloaded dmg to remove Parallels Desktop
- install Parallels Desktop.

Same Problem

I'm having the same problem.

When I upgraded to 4.0.3844 I did not do an Uninstall, just downloaded the .dmg and ran the installer.

After restarting I received the same error message.

Just downloaded 4.0.3844.408728 and performed an uninstall and reinstall as suggested. The problem remains.

Also tried Solution 2 but the problem remains.

Here's my current status:

Scott,

Your problem is different. In your case all kexts are of build 3810. The rest of customers in this thread had only prl_netbridge of version 3810, and the rest of kexts of correct 3844.

I recommend that you try the following:
1. Check in Finder that there are no any Parallels Desktop dmgs are mounted. To be sure, reboot your Mac.
2. Uninstall using uninstaller from 3844. After uninstalling, save the output of the following commands:
kextstat -l | grep prl
and
ls /System/Library/Extensions | grep prl
3. Reboot. Save the outputs of the same commads again.
4. Install
5. Check if the issue is still there.

If it is, please post here the saved outputs from steps 2 and 4, and the actual output of both commands. This will help me better understand what happens on your Mac.
 
Thanks for the quick reply and suggestions. This didn't solve the problem, but the results are interesting:
