Windows says the itunes download file is corrupt and will not install

Im trying to install itunes on my new windows 8 pc. It seems to recognize my software and takes me to a download the 64 bit file (iTunes64Setup.exe). Once the download completes, the file appears in my windows download manager with the message "The signature of this program is corrupt or invalid". If I right click and chose install anyway, I get a message saying that Windows prevented this from running.
I then found the 32bit download file (iTunesSetup.exe). I get the same results as above. Any ideas how to fix this?

I get that all the time with all sorts of programmes. I normally shut down my pc, unplug it, wait for the light to go out on the back, plug back in reboot and it works (with most of my downloads) try this, it might fix it, it might not. I tried this the other day after it kept telling me it was corrupt, then it came down and installed fine. I do this now with every update of every program, if I forget they will all say they have an 'invalid signature' or 'corrupt from source file' etc. Hope this helps you. Also I have to do this before I download music as well, because otherwise it seems to come down with the stupid DRM still on the file, meaning I can't put it on my ipod, convert it or even play it on my system.

If you see the "Purchased" option on the main screen of the iTunes Store, here's what I'd do:
1) Go into your library and delete the file if it downloaded. If not, go to your downloads and delete it from there to stop it from download.
2) Go to the Purchased pane in the main iTunes Store section, locate the item, and try the download again.
Also, you may wish to turn off any anti-virus or anti-malware programs before you try this again, as that sometimes is what can be blocking the download. Otherwise, contact iTunes Store Support:

Select "Save" instead of "Run". Once downloaded, double click the iTunesetup.exe to install.

I have CS6, Master Suite. The application manager program is corrupted and will not load. What can I do?

I'd report the problem to the iTunes Store.
Log in to the Store. Click on "Account" in your Quick Links. When you're in your Account information screen, go down to Purchase History and click "See all".
Find the item that is not downloading properly. If you can't see "Report a Problem" next to the entry, click the "Report a problem" button. Now click the "Report a Problem" link next to the item.
(Not entirely sure what happens after you click that link, but fingers crossed it should be relatively straightforward.)

My ipad connects to wifi for email but when I try to download a game it says the game is 100mb and has to connect to wifi to download? It also won't connect to icloud to download photos?

It's trying to download when you are connected via cellular. Turn cellular Off and then connect via wifi.

I need to install Firefox, but every time I try and download it, the downloaded file is corrupted and I cannot install Firefox on my Windows 7 Desktop PC

I had Firefox installed as my standard webbrowser, but recently it started having problems in regards to websites, some websites wouldn't work as they should. For instance I couldn't open my hotmail email account, it was just a blank white page. Or I would get just code and text on a site that I would normally see images and a designed lay-out. The problems started after I used a demo PC-cleaning program, which removed unnecessary files from my computer. I figured it removed necessary files for firefox to work properly. So I uninstalled Firefox using the uninstaller (but keeping bookmark information etc.) and tried dowloading Firefox 5.0 but the download always crashes or gives me a corrupt file

Do a clean (re)install:
* Download a fresh Firefox copy from http://www.mozilla.com/firefox/all.html and save the file to the desktop.
* Uninstall your current Firefox version and remove the Firefox program folder before installing that copy of the Firefox installer.
* Don't remove personal data when uninstalling.
* It is important to delete the Firefox program folder to remove all the files and make sure that there are no problems with files that were leftover after uninstalling.
You can initially skip the step to create a new profile, that may not necessary for this issue.

Hi, DickmoAZ.
Thank you for visiting Apple Support Communities.
This sounds like a permission issue most likely with the iTunes Media folder. Here is an article that will help you troubleshoot this issue.

I just upgraded my mac book to 10.6.8 and downloaded the new version of itunes. When I try to open it and error message appears saying, "The iTunes Library file cannot be found or created. The default location for this file is in the "iTunes" folder.

I just upgraded my mac book to 10.6.8 and downloaded the new version of itunes. When I try to open it and error message appears saying, "The iTunes Library file cannot be found or created. The default location for this file is in the "iTunes" folder in the "Music" folder."
I have tried a few things but iTunes closes right after i click okay. Anyone know anything?

Look in your Home > Music folder. There should be an iTunes folder there and it should have a number of files and folders including one called library.itl You want to guide iTunes to that file. If you don't see that file or folder then in your next post you will have to be very specific as to what you do see or how you have your iTunes set up because that's where it should be according to default settings.

ITunes comes up saying the iTunes library files cannot be saved. an unknown error occured

iTunes comes up saying the iTunes library files cannot be saved. an unknown error occured
what should i do

Note: Close iTunes completely before doing any of this.
After getting this error, I found a bunch of Temp files in the same folder as my iTunes library. The thing that stuck me as odd about this was that there were 4-5 of them labeled "Temp File.xml", "Temp File2.xml", etc. and when I tried to select any of them, the selected file(s) would mysteriously disappear. I ended up Selecting everything except the Temp File.xml files, and moving it elsewhere (I actually just put in a new folder in the parent folder).
I then deleted/"Move to Trash"ed the folder that used to contain my Library, and renamed the new folder to have the same name as the old folder.
Then I clicked on the iTunes icon (hold down option/alt from before you click, until the "choose library" dialog appears), and chose my old iTunes Library. This re-linked my old library and restored it to how it was before error (-48) started rearing its ugly head.
(Windows users, when you re-open iTunes to link your library back in... you double click the icon, then immediately press-and-hold "shift" until the dialog appears)

I tried down loading mozilla firefox to use as a web browser. It was downloaded 100% then when prompted to "run" the error message comes up with a red cross and the message'This file is corrupted" and won't let me proceed. What do I do now?

It is possible that your anti-virus software is corrupting the downloaded files or otherwise interfering with downloading files by Firefox.<br />
You can try to disable the real-time (live) scanning of files in your anti-virus software temporarily to see if that makes downloading work.

Probably the file got corrupted during the download? Download it again.
If that does not correct the problem, can you share that file download?
