Hello Travis, after installing the new version, my Explorer Thumbnails feature does not work anymore on my Win7/64bit.

I'd like to ask if you could add the involved registry keys to the documentation Help.html, please:

Code:
REGEDIT4

(i)
Did I forget some?

(ii)
I've installed the 64bit version, i.e., LDView64.exe, LDViewThumbs.dll, LDViewThumbs64.dll.
Thus, I don't have LDView.exe. Is maybe LDView.exe missing? Or does LDViewThumbs.dll also use LDView64.exe?

(iii)
Do I have to run some regsvr command or similar to re-register these DLLs?

(iv)
Travis, at the above registry keys dump I spotted that
HKEY_CLASSES_ROOT\Wow6432Node\TypeLib\{9FB564E8-0F22-48FE-859C-372B4A8B1CFB}\1.0\0\win32
points to the 64bit library, although it sits inside the 32bit registry branch.
According to http://msdn.microsoft.com/en-us/library/...s.85).aspx,
this is behaviour by design. But this leads to the effect that 32bit applications get the 64bit DLL this way.
According to http://social.msdn.microsoft.com/Forums/...90dbde68b/
, this can be a problem.

Still, thumbnails do not work here anymore :-(
I reinstalled the 64bit LDView version, and tried running both the
32bit Explorer.exe from C:\Windows\SysWOW64\Explorer.exe
64bit Explorer.exe from C:\Windows\Explorer.exe

Ideas or help, anybody?
