Drag and drop on Vista x64

[fdbck]

I am running v7.02a on Vista x64 Ultimate, build 6000. Drag and drop to and from Total Commander stopped working, started working again and now it does not any more. Right mouse button drag does not work even within Total Commander. I cannot see any cause. It seems to have occurred randomly. I do not know whether it is connected but I also get "Class not registered" error (in local language) whenever I select Explore from the context menu. This may have happened before though; I do not select it often.
Could this be connected to 64-bit shell handlers? If so, how comes it has ever worked at all? Any workaround? Drag and drop to and from other apps is quite essential for me. Thanxalot.

UPDATE:
For reasons unknown drag and drop works again (both mouse buttons). The machine was not rebooted (actually d&d did not work right after boot). Only the following applications have been run that did not run when the problem was present: Office 2007 (Word, Powerpoint, Excel), Firefox, Windows Media Player, PSPad and our proprietary DirectX9 volume rendering software (that supports neither d&d nor clipboard and does not install anything to system). The "Class not registered" error remains.

Maybe, this is the case?

Thanx for the advise Flint, but unfortunately this is not the case. I do not run TC with elevated privileges and d&d does not work both to and from TC. Also the right mouse button d&d does not work even within TC.

UPDATE:
Fresh boot this morning and d&d did not work again. I have just run Windows Media Player and d&d in TC started working. I hope this works next time. Any idea how WMP interferes with TC?

mmm I use also vista 64 bits ultimate I don't have any problems with TC...

I have the same problema than fdbck. I have Vista x64 and TC 7.02a and when I select Explore over a folder I get "Class not registered message".

It is very annoying because when I try to click rigth button over a file and the Properties option it doesn't work, and then I try to open the folder to navigate with Windows Explorer and I get "Class not registered" button, so I have to go to My Computer in Windows Explorer and do it there.

Sounds like the 32-bit part of the registry is corrupted...

[Xusso]

I don´t understand.

You say that it's problem of mi Windows registry or that is problem of Total Commander reading registry?

Can you reproduce this problem in Vista x64, ghisler?

Thanks very much.

[ghisler(Author)]

No I can't, that's why I say that there must be somethint wrong with the 32-bit part of your registry (missing or incorrect options in the OLE part).

[Xusso]

It's strange because this problem occurs me since first day I installed Vista x64 from zero...

Do you know how can be fixed this problem with the registry?

Thanks.

Unfortunately not, I do not have this problem with 64-bit Windows.

I got same symptoms ("Class not registered" error whenever I select Explore from the context menu, and not able to drag&drop too). I tried setting x64DisableRedirection=0 and then it started to work. So (at least at my case) disabling SysWOW64 to System32 redirection was the cause.

Is it possible to make disabling SysWOW64 to System32 redirection not effectively disabling these features?

Well, it's always a possible problem using x64DisableRedirection=1. Why? While it enables access to the true system32 directory, it blocks access to the 32-bit dlls in the redirected directory. So whenever any plugin, system dll or so wants to load a dll from there, it will fail.
