Access denied when trying to open .dmp files with WinDbg

A quick run down on where I'm at now:
I've been getting random BSODs, so I found out how to open .dmp files in the D:\Windows\minidump folder. I installed .Net 4.5 so I could install the Windows development kits, installed the kits, then I opened WinDbg and tried to open the folder. The pop up window informed me access was denied. I moved it to the desktop, tried again, same result.

After seeing access denied I did a search and found out about adding the registry hack that allows you to take ownership of a file. I added the hack, right click -> take ownership. No luck after having done so.

If I could get some help getting it open, it would be much appreciated.

Thanks


Edit: As posted below, from the directory with WinDbg.exe I ran it as an Administrator and it worked.

I double checked to make sure I did everything, and unfortunately it's still telling me:
(Direct from the error box WinDbg gives me when attempting to open the file via open crash dump)
You don't have permission to open this file.

Contact the file owner or administrator to obtain permission.

Am I missing some glaringly obvious step in my frustration with this? And I am going to end up posting the crash dump most likely, I'd just like to take a look at it myself on the odd chance that it's due to something painfully obvious.

Edit: Ha! Got it! From the directory I have WinDbg.exe in, I right clicked it and told it to run as Administrator, then it opened the dump with no issue.
