Can't install Parallels Tools under 11.2

I have a very similar problem happening. It's been happening for about 2 months, not sure I can pinpoint a date or reason. Windows 10, running on MBAir with Parallels 10, which I recently upgraded to 11, hoping this would resolve the issue, which it has not.

I have followed all procedures above, including disabling Windows Defender and Antivirus. Also specifically I followed Guna's instructions through to step 4. I had problems with step 4 as the run command didn't find any installers in the temp folder. So at this stage I ran the PTAgent as administrator.

So If I run it as regular user (which is an administrator anyway) the installer reports failure around 10-15%, but if I run it as Administrator the installer gets to 60%, changes screen size, goes to 67% and pauses there for a few seconds and then reports the failure with a window requiring reboot. The result dow not seem to differ whether AV and Defender are off or on.

I'm getting rather tired of this. All for getting Dynamic Resolution and speakers back.
Hello DavidB23,
Try the below steps and see if that helps you
1. Open the Start menu, type in 'cmd' (Command Prompt) without quotes, right-click on the application and choose Run as Administrator.
In Command Prompt type in: sfc /scannow (hit Return/Enter) and wait until the operation is completed.
2. Follow this article to install Parallels Tools manually ( Follow Scenario 3: Most complicated)
Thanks,
Guna

I tried to follow this procedure to the letter, however there were some things that didn't work...
- The sfc /scannow did not find any errors.
- Windows did not allow me to delete every file for %temp%, even after reboot
- The Parallels Mounter would not work in Parallels 11 so instead I moved the file over across Google Drive.
- I ran the Setup from the copied and extracted folder. it got to roughly the same spot, shortly after it adjusted screen size, and then started reporting Rolling Back action, after which there was a dialog reporting unsuccessful install, and that I should restart. I t created a log, which I've attached. Note that there seem to be 3 major events in this log: Initial startup, first install attempt and second install attempt.

Hello Davidb23,
Please follow the below steps and check how it goes:
1> Start Control Panel, click Hardware and Sound, and then click Device Manager
2> Expand the node that represents sound device and uninstall the sound drivers.
2> Restart the Windows and reinstall Parallels Tools.
 
Guna, the most recent suggestion did work for me, however the procedure wasn't quite as you listed it for Windows 10.

What I did was a search for Device Manager, then expanded Audio and deleted everything in that node, and expended Sound and deleted everything in that node, then restarted. I then ran the Windows Parallels Tools Setup.exe again from when I previously copied it to my desktop and this time it worked successfully.

thanks for pointing me in the right direction. David
 
Guna, the most recent suggestion didn't work. Any other ideas? Thanks.

Hello @SethS1,
Have you tried the following steps?
1> Start Control Panel, click Hardware and Sound, and then click Device Manager

2> Restart the Windows and reinstall Parallels Tools.
 
I had success yesterday via a different path. The update reminder popped up in Parallels, so I decided to give it another go. Here are the steps that worked.
1. Uninstall Parallels Tools in Windows Control Panel before updating to 11.2
2. Let Windows reboot, reset the VM within Windows, reboot Windows again, then shut down Windows
3. Install the 11.2 update via the update reminder popup (previously I'd tried installing it via the downloaded file)
4. Launch Windows - in my case, the Windows desktop was black and the mouse didn't work, but...
5. I used keyboard shortcuts to launch the Parallels Tools installer on my D: drive...and it worked!
6. Reboot Windows
I hope this helps others dealing with the same issue.
Seth
