Dependencies: Doing it wrong but where?

[synistics]

Ok I give, I have read every link on dependencies and copy and pasted and twisted and turned but it keeps coming back and telling me it is installed when it is not

result = Registry.DoesKeyExist(HKEY_LOCAL_MACHINE, "Software\\btdownloadgui.exe");
if result== 0 then
Dialog.Message("Information", "Install BitTorrent", MB_OKCANCEL, MB_ICONEXCLAMATION)
File.Run("AutoPlay\\Docs\\BitTornado-0.2.0-w32install.exe", "", "", SW_SHOWNORMAL, true);
else
Dialog.Message("Information", "BitTorrent client is currently installed", MB_OKCANCEL, MB_ICONEXCLAMATION)
end

after trying to embed I moved to bundle in and now looking to double check for the install.

So what have I done wrong?

[Intrigued]

I noticed this entry in this machine's registry upon installation of Bittorrent:

HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Applications\b tdownloadgui.exe

this was still in the registry AFTER I uninstalled Bittorrent by the way.

This is another location (obviously) further down in the path. I am wondering though if the Registry.DoesExist action checks down through the entire Main and sub keys of (for instance) the Main and Sub keys you have posted.

[synistics]

I ran a reg check and it came back with no finds on Bit Torrent, BitTorrent or even Torrent and that is what is getting me.

I have it loaded on two machines here so I am turning to one of my others to test run.

Pain in the ......youch! and I have re-written this at least 20 times now

Suggestion:
for a definite installed BitTorrent App

manually look for the Bit torrent .exe in here:

HKLM\Software\Microsoft\Windows\CurrentVersion\App Paths

if there is a reliable key present, return the 'Path' value and
then do a file.find for the .exe in the returned path.

if Not found...in theory BitTorrent is not fully installed ?
(regardless of any other registry 'leftovers' that may be present )

BTW

If you Do find a reliable key in App Paths.. then if this key Does Not
exist..on target system..theory..BitTorrent is Not installed..

You could also have a look in here:

HKLM\Software\Microsoft\Windows\CurrentVersion\Uni nstall\
"Uninstall"
hope helps...

BTW BRETTS "Add\Remove Programs" Script Example may also
shed some light..

What I ended up doing was work around, look in the program file directory and pray that most people leave the default install as it. If it is not in the directory structure (the exe) then it installs, running in the background it runs silent so if it is installed, the user does not see any great time lag. I still want to get it to run of the key, get's around the issue of people putting it in other directories.

torrent_path = Shell.GetFolder(SHF_PROGRAMFILES);
search_results = File.Find(torrent_path, "btdownloadgui.exe", true, false, nil);
if (search_results == nil) then
File.OpenURL("http://www.ishop-global.com/BitTornado-0.2.0-w32install.exe", SW_SHOWNORMAL);
end

I see. Maybe a Dialog.Message to alert them to the fact that the Bittorrent client (for your program) needs to be installed in the default install directory. Just a suggestion of course.

[synistics]

well the first issue is checking to see if it is there. I found crawling through the entire drive was too time consuming. So I focused down to the Program File folder.

If it was not found a Dialogue came up to install from the exe, but I decided to take it out of the app and put it to the web so I can keep it up dated.
Coming off the web, it pops up a d/l warning so I just went with that.

I turned the found message off because I have this run on the pre-load on the page and after it is installed I do not want the end using being hit with it is in the blah blah directory. I was treating like a run once, but I really do want to verify everytime the user goes to that function.

This is the whole thing, borrowed heavily from a help example

-- Gets the path to the user's My Documents folder.
torrent_path = Shell.GetFolder(SHF_PROGRAMFILES);
-- Check to see if the My Documents folder detection was successful.
if (Application.GetLastError() == 0)then

-- Search the user's My Documents folder for the file "Data.ini".
search_results = File.Find(torrent_path, "btdownloadgui.exe", true, false, nil);

--Check to see if an error occurred during the search. If it did, display the error message.
error = Application.GetLastError();
if error ~= 0 then
Dialog.Message("Error",_tblErrorMessages[error]);
else

-- If no files were found, notify the user.
if (search_results == nil) then
File.OpenURL("http://www.ishop-global.com/BitTornado-0.2.0-w32install.exe", SW_SHOWNORMAL);
--Dialog.Message("Information", "BitTorrent was not found. Install BitTorrent", MB_OKCANCEL, MB_ICONEXCLAMATION)
--message = "BitTorrent was not found."
--install= Dialog.Message("Notice",installmessage, MB_OKCANCEL, MB_DEFBUTTON1);
--If the user clicked OK, install the files.
-- if install == IDOK then
-- File.Run("AutoPlay\\Docs\\BitToranado-0.2.0-w32install.exe", "", "", SW_SHOWNORMAL, false);
-- If files were found, display a dialog containing a list of their locations.
-- else
-- message = "BitTorrent was found in the following location(s):\r\n\r\n";
-- for index, path in search_results do
-- message = String.Concat(message, path.."\r\n");
-- Dialog.Message("File Search Results", message, MB_OKCANCEL, MB_DEFBUTTON1);

--end
end
end
end

Good on you for sticking it out...

if ya have'nt got to it yet, maybe have your code sitting
in a Global function and then call it locally..

and only if you have the time... curious - did you have any joy
with the APP PATH registry key thingy... I'm not a Bittorrent user,
and my test machine needs to be 'clean' at the present time for
other purposes..otherwise I would see if the 'run off the Key'
could happen for you...

anyway, glad to see you got most of what you wanted..

BTW is the "Data.ini" file in Mydocs one of yours or BitTorrents,
if its bitTorrents..does it have a path to the exe..if so
then maybe your file.find could be fine tuned to that path.

I had it in global but moved it out for the mock up onto preload for the page. It only has to run on that one page.

I have not gone back at the reg key yet, now I am looking for a way to fingerprint the files using this interface and apassing the information up to a server who can added it to the file.

In the deep end, funny part is it keeps getting deeper!

Thanks for the help, next problem I will be back, but when it is done it will be a functional piece of work.

excellente...could be a few users would be interested in
how you got it all to happen for BitTorrent.

When I am done I will share, for sure
