Itunes 10 installs but says unknown publisher invalid digital signature

i need help as i would like to upgrade to itunes 10. I have tried absolutely everything such as restarting computer and resetting tools on internet.
it installs perfectly but once it has finished it comes up with an error message saying unknown publisher. this application has a n invalid signature
please help as i need to upgrade my ipod touch version to 4.1 as well as itunes 10.

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.)

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

For general advice see Troubleshooting issues with iTunes for Windows updates.
The section Install missing components may allow you to install Apple Application Support.
The steps in the second box are a guide to removing everything related to iTunes and then rebuilding it which is often a good starting point unless the symptoms indicate a more specific approach. Review the other boxes and the list of support documents further down the page in case one of them applies.
Your library should be unaffected by these steps but there is backup and recovery advice elsewhere in the user tip.
If the advice above doesn't resolve things you could try this alternate version:
iTunes 12.1.0.71 for Windows (64-bit - for older video cards) - itunes64setup.exe (2015-01-28)
which is a 64-bit installer for the 32-bit version of the core application, similar to previous 64-bit releases.
Or roll back to the previous build:
iTunes 12.0.1.26 for Windows (32-bit) - iTunesSetup.exe (2014-10-16)
iTunes 12.0.1.26 for Windows (64-bit) - iTunes64Setup.exe (2014-10-16)

I'm trying to get iTunes 10.5 but my computer told me 'the signature is invalid'

I'm trying to get iTunes 10.5 but my computer told me 'the signature is invalid'
How can I solve this?

Hi Rick,
by "repair" I mean I went to the control panel, option - programs and features, and in the list of all my installed programs I selected "Apple Software Update". On top of the screen you find the options Uinstall, Change and Repair. I clicked the repair button and that did the trick. After the repair I could uninstall the program. I also uninstalled iTunes, Apple Application Support, Apple Mobile Device Support en Bonjour, thus all Apple programs. Then I installed iTunes 10.5 again and everything went fine.
Success,
Peter

HT1420 Please help.... cannot get into the ITUNES account. It says unknown error has occured. Is there a problem with ITunes?

Please help.... cannot get into the ITUNES account. It says unknown error has occured. Is there a problem with ITunes?

Same thing happened with my iPhone 4S - no one is any help. Thanks Apple for such a crappy update! I've called Apple, they say the SIM card needs replacing, I go to my service provider they tell me nothing wrong with the SIM card - provider tells me I now need a new phone. Sheesh! If someone has a solution to this it would be greatly appreciated.

ITunes invalid digital signature

I tried to update iTunes the other day. After it installed it rebooted and then said "files missing". So I tried to download it again but it was horribly slow (which I attributed to the Christmas rush). I figured I would wait until today. Now I keep getting a message saying "Invalid digital signature". WTH?

Perfect, thanks.
I see that one's got an SPI firewall:

By way of experiment, try disabling the firewall and doing another iTunes download. Are you able to get a working installer this time?

ITunes won't download- "invalid digital signature"

I'm trying to download the new version of iTunes. It starts to download fine, but at the very end, a box comes up and says that windows has cancelled the download because of an "invalid digital signature" and then just x's itself out. How can I solve this problem?

BigChap posted this reply ealier - it worked great for me.
right click on Internet Explorer on your desktop and choose Properties/advanced and check the box "allow software to run or install when signature is invalid".
hit Apply. then close Internet Explorer and restart. got to download site and choose "run" instead of "save". worked for me after dozens of other attempts failed

Cannot install Apple iPod and iTune downloads (invalid digital signature)

Every time I try to install something from apple.com it won't let me. It brings up a message box that says something like "Invalid digital signatue" and it won't even give me a choice as to whether or not to download it. Has anyone else experienced this? If so, how did you fix it?

I try different browsers and they all have certificate notice alert.
New IE on win8 by default not allow to enter secure page with expire certificates.
I hope that cisco will make new firmeware with functionality to add costume certificate pfx for example.
Cisco support lower encryption type. Every new windows encrase cryptograpgi that IE support by default. Look IE about to see type 64 or 128 or 256…
On xp will work good, but we are now in era of win 8 with IE that support by default 128 or 256 depending home or server version.

Invalid Digital Signature and corrupted files???

ever since i have been asked to upgrade to 7.2, i have not been able to ugrade to 7.2 due to a invalid digital signature. and when i tried to DL music it always says corrupted file try again later, been like that for a week, and i have a spy-sweeper which i've disengaged to see if it helped, nope.

ever since i have been asked to upgrade to 7.2, i have not been able to ugrade to 7.2 due to a invalid digital signature.
although the following document refers to a slightly different error message, perhaps give it a try:
iTunes: Windows reports that iTunesSetup.exe is not a "valid Win32 application"
... but if no joy there, try the following Microsoft document:

JRE - Error 1330 (Invalid digital signature in data1.cab)installing1.6.0_13

I cannot install jre6 update 13. All attempts from using full offline download result in the following error message:
"Error 1330. A file that is required cannot be installed because the cabinet file C:........\Java\jre1.6.0_13\Data.cab has an invalid digital signature. This may indicate the file is corrupt."
It looks like there is a problem with the 1.6.0_13 consumer JRE offline installer once it was digitally signed. Is it possible the digital signature of the Data1.cab file was corrupted during extraction. I am wondering if Sun needs to rebundle this offline package again.
I have disabled virus checking, and whatever else I could think of!
System is Windows XP SP3.
Has anyone else experienced this problem, or have any suggestions?
Thanks,
Paul

Afternoon,
I have had this error on a hand full of WXP SP3 workstations running 1.6 update 16. I am not a smart person, but I do know how to search. I found a fix a tried on a similiar error.
On one of my problem children I did the following.
As Admin verify rpc service is started.
from a CMD prompt
regsvr32 softpub.dll
regsvr32 wintrust.dll
regsvr32 initpki.dll
regsvr32 dssenh.dll
regsvr32 rsaenh.dll
regsvr32 gpkcsp.dll
regsvr32 slbcsp.dll
regsvr32 cryptdlg.dll
I believe the initpki.dll took a few to respond. After that I restarted and tried the install on the problem child again. Success. Since then I have been going back to my other problem children. I try the install without the fix and have not had a issue, YET, installing update 16. It's PFM.

Every time I try to download itunes 10. says unknown publisher. Whats next?

every time I try to download itunes 10.5.8 after waiting up to 50 min. each time it wont download and has the message unknown publisher. Whats the next step?

This forum is for questions from those managing sites on iTunes U, Apple's service for colleges and universities to post educational material in the iTunes Store. You'll be most likely to get help with this issue if you ask in the general iTunes forums.

HT5770 Cannot install QuickTime 7.x security update and why does the file say 'unknown publisher'?

I downloaded QuickTime 7.x security update (recommended by my VP), but I cannot run. I am getting the message 'Unknown Publisher', but when I click run, nothing happens?

Hello,
Seems someone from Apple corrected the problem.
I just downloaded a new version, again, due to upgrade to a larger HDD, and the new installer does have Apple name identified.
So try it again.
Good luck.

I can't download yahoo games. when i do i get a page saying "unknown publisher" won't open

Can't download yahoo games. The Oberon company tells me it is either my windows firewall or my microsoft anti virus. What can I do to resolve this problem? Some games do make it through but only a few. Thanks for the help.

Hi PonyBoy,
When you see the "unknown" Publisher, does it give you the chance to Click and allow the program to run? If so, then Click Yes (or some form of the affirmative).
If there is no question of the type described (no chance to download / run the program),
THEN
You can adjust the settings in Windows Firewall to ask you before blocking new programs. It can become a pain to answer all the time, so use this setting when you need it and then switch back to normal blocking.
You may need to have administrative control to change the settings - if the settings won't change for you, log in using an account that has Admin rights.
The settings are outlined in this help file:
Understanding Windows Firewall settings
The setting you will use:
"Notify me when Windows Firewall blocks a new program" "If you select this check box, Windows Firewall will inform you when it blocks a new program and give you the option of unblocking that program."
NOTE:
If you are in a Public place (not at home, and not in a safe environment), the Public settings are more restrictive to better protect your computer. You can change the settings, but you do open your computer to other "nasties" out there - Open / Change the settings for Public at your own risk.
You didn't say anything about another (non-Microsoft) kind of AV software you might have...
If you have another (additional) Anti-Virus on your computer, there should be rules you can use to change the way incoming traffic is handled. If you have Norton, it will block things that you've never heard of, it will lock up your computer, it will misbehave. Nothing can be done about Norton, IMO. You need a good Anti-Virus program to protect your computer - invest some time and find a decent program. Avast, AVG (both have free versions), and even Kapersky (pricey and inelegant), are better than Norton. If Norton is all you have and all you can get - keep it - it's better than nothing and will do some good.
I hope this helps.
