Unable to install Parallels 12 on Mac (os x Sierra 10.12.3). Error

Problem Report ID number 154435574
Problem ID: 15380
I tried the suggested fixes in Article ID: 114703 and 118079. No issues there. Disabling firewall and antivirus did not help either. Please help!

 

Please quit Parallels Desktop.
Then, try uninstalling/installing Parallels Desktop steps below:
1. Open Terminal.app on the Mac.
2. Proceed with executing the commands below one by one:
sudo rm -rfd /System/Library/Extensions/prl
sudo rm -rfd ~/Library/Preferences/com.parallels
sudo rm -rfd /Library/Preferences/parallels
sudo rm -rfd /Library/Parallels
sudo rm -rfd ~/Library/Saved\ Application\ State/com.parallels.desktop.console.savedState
sudo rm -rfd /Library/logs/parallels.log
sudo rm -rfd /Library/Preferences/Parallels/
sudo rm -rfd /Private/var/db/parallels
sudo rm -rfd /Private/var/.parallels_swap
sudo rm -rfd /Private/var/db/receipts/'com.parallels*'
sudo rm -rfd /Private/var/db/Parallels/Stats
sudo rm -rfd /Private/var/root/library/preferences/com.parallels.desktop.plist
sudo rm -rfd ~/Applications\ \(Parallels\)/
sudo rm -rfd /Applications/Parallels\ Desktop.app
Please install Parallels Desktop 12.

 

Tried that and I still get the same error. When I open the Parallels in my application folder, it allows me to sign in and create a new virtual machine. Havent tried that yet. Does this mean its functional despite the error?

 

I learned today that placing the installer in the Applications folder allows it to run without the error. I had been placing the DMG in various places, and launching the installer from the image's mounted volume with bad results. Sierra has some new safeguards. Running some apps outside the Application folder may get different results than in previous Mac OS versions.

 

Please clarify the error message, could you share a screenshot of the error message to investigate further.

 

The computer has been delivered already, so I am not able to get a screenshot. Here is the thread I began on this subject: https://forum.parallels.com/threads/error-15380-macos-sierra-parallels-12.340024/#post-818589
