Context menus and desktop disappear

[Ulrich_Trutter]

Parallels Desktop 11 Pro for Mac Edition
Version 11.1.3
Guest: Windows 10

When I call the contextmenu on the desktop (right click) sometimes the menu is shown just for a second maybe and the it is completely empty.
This also happens with a treeview in another program.

The solution I found out so far is to resize the window in which Paralells runs. I am working with a big monitor. But this solution seems not to work all the time: sometimes the whole desktop becomes black and nothing can be seen.

So my question is: How can I avoid this behaviour?

Hello,
Some Windows-based programs is not adapted for such high pixel density (DPI) resolution of the Retina display: Windows virtual machine resolution becomes very high thus everything is too small; in-program fonts, UI buttons or images are not rendered properly. Please refer to this article to fix the issue.

Thanks for your answer, but:
It has nothing to do with a windows-based programm because the problem already is there when I right click on the desktop. So it is Windwos itself.
It also does not have to do with Retina, because my monitor (Sharp PN-K321) dows not offer Retina.
Any other suggestions?

Reinstalling Parallels Tools seems to have worked. I have not had any problems since then.
Thanks.

I'm having an issue after updating PD11 (v11.2.0 32581) for Mac (El Cap.), the coherence mode is greyed out, I have limited screen real-estate, unable to open MS applications as well as the infamous "Windows cannot access \\MAC\HOME\Desktop" error. After searching through the KB forum, I found I may need to check and verify all WINDOWS Updates are installed--also found the following error "Windows Update Error "0x80070002". I was missing roughly five (5) important updates. All Windows updates have been completed. I also found solutions where the Parallels Tool needs to be reinstalled. Unfortunately, I receive yet another error, "There was a problem updating Parallels Tools", I'm prompted to restart Windows and try again. The Parallels Tools Installation fails repeatedly.

Any resolution would be greatly appreciated. Thank you.

Disabled virus protection, cleared registry of Parrallel Tool, ran sfc scannow (no errors). Ran tool install as System Admin, once install was roughly 57-60%, failed again (repeatedly) with the same red screen posted earlier.

Any other suggestions by chance? Thank you for the quick response!

Hello RobertD7,
Instead of disabling the Antivirus kindly try to uninstall Antivirus from your Windows VM and install Parallels Tools manually and let us know if it makes any changes.

Greetings @Pradeep@Parallels, per your instructions above, I uninstalled the Antivirus protection from the Windows VM, restarted, initiated P.Tools installed and it failed. However, upon restart of the VM, I once against initiated the install and it was successful after the second restart. I am excited to report, my Coherence Mode is up and running and all applications can be accessed. Thank you for your assistance!
