Unable to correctly read value of a REG_DWORD from the windows registry

[GeorgeB]

I'm writing a little applet that basically tells you when Windows was installed.  There is a REG_DWORD in Windows that gives you this. It's basically a value that is the # of seconds from 1970.

The location is:  "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\InstallDate"

So if I run this in AutoIT, I should get the value displayed within the msgbox:

MsgBox($MB_SYSTEMMODAL, "InstallDate Test", RegRead("HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion", "InstallDate"))

However, what happens is it always returns a value of "0"  I tried this on several machines (Windows 8, Windows 8.1 and Windows 10). 

Am I missing something?  If I manually view this REG_DWORD with RegEdit, it shows me the HEX value, or I can view the Decimal value. I don't care which value AutoIT reads, as I can always convert back and forth, but I just don't see why it can't read a value from this REG_DWORD.  As a test, I've read other REG_DWORD values, and with most it doesn't return any value, not even a 0.

Please, even if you guys have some other (perhaps better) way to read the Windows install date, I would still like to find a resolution to this problem, because I want to understand why I am having so much difficulty with reading REG_DWORD values from the Windows Registry with AutoIT.

Thanks for any help!

If your script is compiled as 32-bit you need to use HKLM64\SOFTWARE\Microsoft\Windows NT\CurrentVersion\InstallDate

It's six years later and this post bailed me out of being stuck on the same issue.  Thanks to for GeorgeB for posting the question and Subz for the solution.
