ITunes 7: unknown publisher?

a message keeps coming up that iTunes is from an unknown publisher and i can only click 'ok' so i can't go any farther in the installation. It also sometimes says something about a cabinet?
It first says: Error 1905.Module C:/Program
Files/iTunes/iTunesminiplayer.dll failed to unregister. HRESULT -2147220472. Contact your support personnel
Then it says: The cabinet file: 'itunes.cab' required for this installation is corrupt and cannot be used. This could indicate a network error, an error reading from the CD-ROM, or a problem with this package
please help me....thanks so much if you do!

hmmm. with the unknown publisher message it might be worth checking through this Microsoft KB doc:
(MS) You cannot install some updates or programs
... if you can get a functional itunes installer (one that doesn't throw that publisher message), but still run into trouble with the 1905, try working through the general advice in the following document:

Cannot install itunes - message "unknown publisher & no digital signature

I have been using itunes for ages but on Tuesday when i tried to update my IPOD it froze so i then checked that i had the most up date itunes by downlading the latest version which i have done loads of times without any problem. THis time however every time it downloaded it came up with the error message "unknown publisher" and "no digital signature". It gave the option of running the program still but then it would just close and not do anything!!
I have been to the apple shop and my ipod has been sorted although everything has been wiped as they had to restore it. I have again today tried to download itunes but am still getting the same message so cannot put music back onto my ipod to use!!
I use windows vista and have an ipod touch. We hav also tried another computer but are still having the same problem. Any ideas??
Thanks

Should I just get the itunes setup folder from a person that has got it already?
Yes, that usually works. (So long as we can get an undamaged installer onto the PC with one of these, it will usually install fine.)
Another thing that is worth a try is seeing if you can connect to a different wireless network, and downloading the installer while you're connected to the internet that way. (The wireless router being grumpy is a common cause of this sort of thing, so by connecting to a different network you're taking the grumpy router out of the equation.)

Getting an "unknown publisher" error when downloading itunes

I am trying to download the latest version of Itunes. I keep getting an "Unknown Publisher" message from Internet Explorer. I went through the troubleshooting and removed all apple apps. Now I am stuck. Any ideas?

That suggests that the installer is getting damaged during the download.
I'd first try downloading an installer from the Apple website using a different web browser:
http://www.apple.com/itunes/download/
If you use Firefox instead of IE for the download (or vice versa), do you get a working installer?

Cant download itunes update dur to Unknown Publisher - please help!!!

Please help me I don't know what to do next. When I try to update itunes it downloads but then comes up with a message telling me download failed due to unknown publisher. I tries following advice from another post but this didn't work.
Thanks in advance
PS also cannot download new iphone software but i will post that in the iphone section ...

Thanks that worked - do you know why that is?
excellent news, Jay.
We (the one's of us who are troubleshoting the error) think it's something to do (in some cases) with the network settings on certain kinds of network setups (possibly if you're connecting to a LAN which has an internet gateway, rather than, say, connecting wirelessly to a router plugged into a DSL or Cable modem. Bloody Yeti discusses that in this post:
http://discussions.apple.com/message.jspa?messageID=10547579#10547579
Off in a different thread (I've just discovered) Bloody Yeti was also simultaneously discussing trouble with recovery mode, so plausibly the two issues (getting the ipod software and getting the iTunes installer) are connected:

ITunes "unknown publisher" error

I tried to update iTunes to v8 via Apple Software Update but it failed due to some error with the updater. I uninstalled Apple Software Updater and also iTunes 7.1. I tried then to install iTunes 7.1 so I can re-download Apple Software Updater and I'm getting an error saying "unknown publisher" and even if I try in install iTunes 8 nothing at all is happening.
Any ideas?

Download itunes 10.3 - unknown publisher??

when i try to download itunes 10.3 I am getting a internet security warning pop-up screen that states Name: itunes64Setup.exe Publisher: Unknown Publisher... then it goes on to say that 'this file has been blocked because it does not have a valid digital signature that verifies its publisher.' How on earth could it be that Apple would not be up to date? any ideas as i reckon i have tried this 10 times now. I also tried to save the file and then open. that doesnt work either. I am set up as administrator so that isnt a problem i dont think....??

Hi.
I was having the same problem. Have you rectified the issue since your post.
if not, are you connecting to the internet through a wireless router. if so you need to connect through a LAN and this will allow it to be installed.

"Unknown Publisher" error message during installation

Ok, I have tried for several days and even got ahold of Microsoft on this issue. Every time i go to download Itunes the download is ok, but when it goes to install Itunes, I ALWAYS get "Unknown Publisher" error message and installation is cancelled. How do i resolve this issue? Any ideas?????

Welcome to AD!
Some folks have had success by downloading and installing QuickTime standalone, then installing itunes after QT. iTunes needs QT codecs to play audio & video.

Make sure to get the version withOUT itunes.

Digital Signature/Unknown Publisher

So I was trying to download iTunes 10.5. The first time I did it a "digital signature" message popped up and then retarted the download, but it popped up again. I went on to this discussion board to find some help. Some discussions said to delete (remove) everything apple and restart the iTunes. I did this and now I am getting a message that says "unknown publisher" everytime I click the "run" button. I have tried to download this iTunes about 8-10 times in the past two days.
some discussions say to try Firefox, but I don't want to do that. My last resort is to call the tech support and ask them for help because last time this happened it took us about a couple of hours.
Thanks in advance!

How are you downloading iTunes?
Generally speaking it is best to download it from here:
http://www.apple.com/itunes/download/
Rather than using update. You need to save the file on your PC and run it from there.
If that doesn't work can your try another browser?
Also it might be worth restarting your router.

Cannot download firefox... due to error of unknown publisher using windows 7

firefox%20Setup%203.6.13.exe
unknown publisher
could not download
previously was downloaded...and I was reinstalling it... but can't... I changed my security setting to Medium to see if this would help

Yeah, the 64-bit tip isn't going to help.
Let's instead try reregistering your Windows Installer Service.
First, launch a command prompt as an administrator. In your Start search, type cmd then right-click on the cmd that comes up and select "Run as administrator".
At the command prompt:
Type %windir%\system32\msiexec.exe /unregister and hit enter.
Type %windir%\system32\msiexec.exe /regserver and hit enter.
Close the command prompt, restart the PC and try another iTunes install.

HELP - unknown publisher error

In preparation of my new iphone turning up tomorrow - thought would download itunes. Never used it before. 3 hrs in and still not installed!! Keep getting Unknown Publisher Error. Things I've tried so far: using Mozilla instead of IE. Emptying Temp folder. Downloading QT separtately. Numerous restarts. Help me please!!!

You've been doing the sensible things with your troubleshooting, lee.
How are you connecting to the internet?
For example, my Lenovo T61 is connecting wirelessly to a LinkSys WRT54G wireless router that is plugged into a Motorola SB5100 Surfboard cable modem.
What sort of setup do you have?

Can't install Firefox on Windows 7 home premium. Get a Security warning "Unknown publisher".

Tried downloading from link below:
http://www.mozilla.org/en-US/firefox/all.html
It downloads, but a internet explorer security waring pop up stating
Name : Firefox%20Setup%207.0.1.exe
Publisher: "Unknown Publisher".
If I click Unknown Publisher, it let me install a certificate, but then I run the set up it says that "file is correpted".
I tried downloading firefox from few different places but the result is the same. please help.

Run the Creative Suite Cleaner Tool, try again. and if you bought it used, you will have to run a Transfer an Adobe product license to handle activations properly.

Unknown publisher message

Been lurking in the forums for a while - and I've found many
useful responses already. I've got a question that I've seen asked,
but never really answered, so I'll throw it out again.
We're publishing standalone EXE files from Captivate 2.0 for
our people to use. We're linking to them through a separate
customized html page (using EXE rather than html/swf for now
because we have video files embedded, and the EXE simplifies things
for now by creating one file rather than multiple files per movie -
several other reasons, but we've played with everything as
options). For now, the EXE files are located in the same folder as
the html page.
We briefly tried linking to the EXE files through hyperlinks
in a Word document. This triggered a single dialog box asking if
the user really wanted to open the file. We're changing this launch
page to an html page for several reasons. Unfortunately, when
linking directly to the EXE files from our new launch page, we get
two dialog boxes, which is pretty inconvenient. The two messages
are:
1) Do you want to run or save this file? (of course - that is
why we linked to it...) --> Run
2) The publisher could not be verified. Are you sure you want
to run this software? (Unknown publisher error) --> Run
First, is there any way to get around one or both of these
dialogs? It seems to me to be a Windows and/or browser security
issue, but I can't seem to get around the issue.
Second, if I can't get around both of these dialogs, has
anyone been able to use a digital certificate to prevent the
Unknown Publisher error? If so, any good resources on how to do
this?
Thanks in advance!
David
Update:
I think I found a decent solution for this. I am using
MenuBuilder, making relative links to the executable files (link to
the file on your computer, then delete everything but the filename
to make it relative to the MenuBuilder file's location), and then
exporting the Menu Builder as an EXE file. This seems to eliminate
all of the dialog boxes... It works like magic from my computer,
but I haven't yet deployed it, downloaded all the files from the
Web, and then tried it. We'll see...
Thanks for the suggestions.
David

Thank you for the responses. Yes, I agree that the html/swf
will be the better option for us down the road - this is more for a
short term phase of our project.
We aren't accessing the EXE files directly from the Web -
they are downloading them to their own computers, along with the
html file we've created to launch the files, and then accessing
them locally for classes. We've developed a custom LMS-type of
application to host the files - the next version of that app will
let them download everything in a packaged zipped format, so we'll
use the html/swf outputs at that time. It was just too confusing
for our users to use multiple file types (swf, html, flv video,
etc.), when the EXE made it simple to download and use.
For the present, however, I'm still trying to figure out the
best way to avoid our extra dialog boxes... I believe the fact that
they are downloading the files from the web may contribute to the
problem, but I get the same message when I access the local files
I've created through an html link.
Any other recommendations, or does anyone have any experience
digitally signing Flash .exe files so that we could be a trusted
publisher? I'm hoping that this could be a partial solution - we
should have a valid certificate, but I'm not sure if I can do it
with Captivate files.
Thanks,
David
