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 Regards Chris Mulcahy
