I have installed the most recent version of parallels 11 without a problem. But I am unable to update my windows 8.1 to 10. Each time I try I get an error message window that reads "An unknown command-line option [/Dynamic/Update] was specified." The window shows up with a single "OK" check box that I have to click and then the system drops out of the update process.

I ran the Windows Update Diagnostic utility and it seemed to find and fix some errors, but the error message still occured.

Any suggestions?
 
To upgrade to Parallels Desktop 11, please follow the steps given below:

- Check your virtual machine is a 32 bit or 64 bit as per http://windows.microsoft.com/en-IN/windows7/find-out-32-or-64-bit
- Please run the 32 bit tool http://go.microsoft.com/fwlink/?LinkId=616935 if your virtual machine runs 32 bit or run the 64 bit tool http://go.microsoft.com/fwlink/?LinkId=616936 if your virtual machine runs 64 bit
- On the two options, select the second one [Upgrade a different computer] and click next.
- On the two options, select the second one [ISO file] and click next.
- Save the file on your desktop.
- Connect the ISO file to the virtual machine as per http://kb.parallels.com/8638
- Open File explorer and go to 'This PC' and then run Windows 10 from the mounted file.
- Proceed on with the installation and check if the issue persists.
 
If I do it this way it asks for a product key. It does not accept the product key from my original Windows 8.1. If I click skip I get an error saying "Windows could not display the images available for installation." This is a different error from before.
