History explained as the connection problem with my ISP earlier caused the GW2 download problem later with the patch:
Recently installed windows 8 pro on notebook.
Could not access GW2 as had a problem with the connectivity which was caused by myself, the user. Fixed that by disabling the re-enabling the network interface card and fixing the DNS settings.
While that allowed me to logon ok, the next problem occurred with a patch that told me either the GW2.dat was in use by another process or not accessible made me hunt for a solution.
Permissions:
First, I checked permissions as really – checking if a process is in use and by what is a hit and miss affair in task manager.
I confirmed correct permissions where in the Program Files x86 GW2 folder: Trusted Installer and All Application Packages had full control.
I confirmed that Kasperky 2013 considered GW2 trusted and gave additional non-surveillance to its network activity.
GW2.dat file:
I copied the gw2.dat file and renamed the gw2.dat file to gw2.dat.old when the copy was made.
The GW – copy.dat could not be renamed, that gave an error about “com surrogate” was in use, which is possibly the reason why GW2 had issues with not being able to update the GW2.dat file in the first place.
I looked at various causes, like DEP and graphics drivers causing the problem and ignored those solutions, drivers change too much to want to go down that track.
The Windows 7 solution I found most feasable and it should fix the the ability of GW2 to download the patch because when I did it in Windows 8 it was a success.

Click Start.
In the Search Box type CMD
Right click on the Command Prompt icon.
Click Run as Administrator.
In the Command Prompt black window type: regsvr32 windir/System32/vbscript.dll and hit Enter.
The system will return with the following message: DLL Register Server in C:\Windows\System32/vbscript.dll has been successful.
Now click Start.
Click Computer on the right.
Click Folder and Search.
Click the View tab.
Tick Always show icons never thumbnails.
See if this solves the problem.

My Windows 8 solution:
While this solution was written for Windows 7, I worked it out for Windows 8 by going into settings (access that by using mouse in far bottom right corner) , control panel, all objects in control panel, folder options to check the view options as per my quote.
Then I used the mouse again in the far bottom right to pull up the search options to use Search. In applications I typed RUN and thus had the command line.
I am already an administrator anyway, so did not have to use “run as” to become one. I typed the line:
regsvr32 windir/System32/vbscript.dll
This told me I was successful.
Gw2 now works fine, I clicked on the GW2.exe and the patch completed.
Good Luck to everyone else, hope this helps.
