open windows explorer and at the top go to tools, folder options, file
types and after finding your type, delete that entry. Next time you
try to open that kind of file it will ask you again.

Try this. First, open Notepad. Copy and Paste the following, not including
the dashes, into Notepad:

---------------------------dashes-----------------------------


Windows Registry Editor Version 5.00

[HKEY_CLASSES_ROOT\.dll]
@="dllfile"
"Content Type"="application/x-msdownload"

[HKEY_CLASSES_ROOT\.dll\PersistentHandler]
@="{098f2470-bae0-11cd-b579-08002b30bfeb}"


---------------------------dashes-----------------------------


Save the file as dll.reg (no .txt extension).

In the Registry Editor, go to this key:

HKEY_CLASSES_ROOT\.dll

In the LEFT-hand pane of Registry Editor, right-click the key ".dll" (it
won't have quotes) and choose Delete.

Then go to this key (it may not exist):

HKEY_CURRENT_USER\Software\Microsoft\Windows\Curre ntVersion\Explorer\FileExts\.dll\UserChoice

In the LEFT-hand pane of Registry Editor, right-click the key "UserChoice"
(only!) (it won't have quotes) and choose Delete.

You can close Registry Editor. Double-click on
dll.reg, and allow the Merge. Log Off, and then back On.

Just a thought, but it might be better if you put Notepad in your SendTo
folder, and read a .dll that way. Sending it to Notepad won't change the
association.

I have windows vista home premium, it doesn't let me save the notepad file as
*.dll, it only gives me the *.txt option...
or at least I don't know the way to do it...
Thank you for your support!!

The problem is that I have windows vista home premium in my pc and Folder
options is a little bit different. I can't follow you...
Thank you for the time.

Well, no, you don't want to save the file with a *.dll extension. You want
to end up having a file with a *.REG extension. It doesn't really matter
what name you give it, just so it has ".reg" at the end. You could just
save the file with a *.txt extension, which by default is what Notepad will
want to do. Then right-click on it, and choose Rename. Add .reg to end of
the name. Windows will ask you if your are sure that's what you want to do.
Click yes.

Then double-click on "whatever.txt.reg", after you have done the
things with Registry Editor that I noted. Do be careful to be accurate when
editing the Registry; Follow my instructions closely. If you have any more
questions, post back.

That's because the advice you were given pertains to XP, not Vista. From
Control Panel open Default Programs and select Associate a file type or
protocol with a program.

Hi GTS. You are correct about the difference in XP and Vista. The problem
is that Control Panel\Default Programs\Set Associations, normally, has the
..dll extension under the Current Default column as "Unknown application".
Unfortunately, clicking on Change Program won't offer "Unknown application"
as a choice, but merely change it to a different inappropriate program.

Ok, I got it now but I can only associate my *.dll file with a new program. I
don't see the undo association option. What I want is to let the dll file
like it was before I made the change by mistake. In other words: "to undo the
open with option..."

Thank you GTS

Gotcha. I think you're right on target then re. having to fix it in the
registry.
