Why do i get an error code 0xc0000020 when i try and open free trial of ArGIS Pro on my desktop after download.


To start with

After I downloaded ArcGIS pro and tried to open the program on my desktop/PC, the instruction was I need authorisation from a "named user". I had registered as a named user as per the instructions and default settings of the download. While I was providing my information downloading the program I registered my name as the Organisation and myself with administrator privileges. However, once I tried to open ArcGIS Pro on my desktop/PC it said I did not have "named user" privileges.


I subsequently emailed myself to ask permission to use the program but the email was not received, so I could not action the request, it did stay in my access requests in the online account? 


I have since followed all instructions provided by tech support including:

Version of Internet

Available Memory >4GB

No Python installed

Windows is updated

Changed file names Roaming etc to \OLD

Uninstalled and Re-installed at least 4 times

Repaired the install x 2


I think tech support in Brisbane, in particular one Lady who has been assisting iss doing all she can, it seems from forum posts that this is quite a common problem and requires a fix by ERSI. I don't wish to uninstall Windows, however, I have uninstalled Chrome.


Any assistance would be appreciated
