"Some installation files are corrupt." Trouble Upgrading iTunes.

Please help. I have been trying to upgrade iTunes from the apple site, but everytime I try I get this error message, "Some installation files are corrupt." If anyone has any advice, it would be greatly appreciated. Thank you.
Windows XP

I also had this problem and solved it by deleting the downloaded file, turning off the firewall and Cybersitter (content filter) and downloading itunes setup again. It then worked perfectly. I therefore recommend you disable any firewall or filtering software you may have (temporarily of course) and try again. Good luck.

CRVS2010 Beta -CRforNET40_x86 - I get 'Some installation files are corrupt'

Hi,
I just downloaded CRforNET40_x86 from the "Blogs" page and got the 'Some installation files are corrupt' error message on trying to run/extract the files.
The message also asked me to download the file again but it would seem pointless as I didn't get any download errors so I'm assuming that the file may be corrupted. Would you please have it checked so that I can try downloading it again.
Thanks,
Michael

Sorry Ludek for not specifying the link.
I downloaded the file from "/people/blair.wheadon/blog/2010/07/29/crystal-reports-for-visual-studio-2010-beta-2-and-runtimes-now-availableCystlR%2528SAPWeblogs%253ACrystal+Reports%2529".
Anyhow, I decided to download it again and this time it did run properly/extract and install. Don't know why it didn't work/run the first time but the main thing is that it worked.
Thanks for your prompt response.

Some installation files are corrupt. Please download a fresh copy and retry

Hello,
I have installed BusinessObjects XI 4 SP02 on server 2008 R2. BO Client tools with sp02 and Patch 8 is also installed.
When tried to install BO Server patch 8 (ENTERPRISE02P_8-10009484) I get this error;
"Some installation files are corrupted. Please download a fresh copy and retry the installation."
while unzipping, WinRAR window throws below message in red;
CRC failed in dunit
\crystalreports.boe.clientactions.java.webpath_bundle-4.0-core-64\content.cab
I have tried twice with fresh copy downloaded on same server and still can't pass this error.
Loading latest patch such as patch 10 is last option since all client machines here are on patch 8.
Has anyone seen this behavior?

Hi,
I'm installing an updated version of Dashboard Design (SP04 Patch 0 - includes FP3). However, during the extraction of the installation file, I get the following message :
"Some installation files are corrupt.
Please download a fresh copy and retry the installation."
I tried to download the application again from SAP Service MarketPlace but the same message rises during installation.
The downloaded file is XCELSIUSENT04_0-20006661.exe
Did anyone manage to correclty install this version ?
Thanks for your feedback.

CRVS2010 Beta- Some Installation files are corrupt

Hello,
I am trying to download the CRVS2010 beta. It downloads and when I run the cr4vs2010.exe I get this error:
"Some installation files are corrupt.
Please download a fresh copy and retry the installation"
I have tried redownloading multiple times with different browsers to no avail. I need this downloaded ASAP as we have multiple crystal reports that were ported over from VS 2008.
Please Help.

Hi Burns,
I just downloaded from the US link and ran the installer and it worked for me. It extracted all of the files and it appears the setup engine is almost the last file it extracts.
I believe this is a permission issue. Does it get as far to create this folder:
C:\Program Files (x86)\SAP BusinessObjects\InstallData\logs
or any \SAP BusinessObjects folders?
Try adding the EXE's to the trusted list in your Anti-virus software and/or firewall and or anywhere else Windows may be blocking executables.
Thank you
Don

ITunesSetup says some install files are corrupt, iPod wont be read by pc..

My ipod and itune were working fine earlier today and before, but whenever i try to update to the latest verion the install says some install files are corrupt, and now my itunes suddenly no longer reads my ipod... This is like the 20th time this ipod not being read by pc problem has occurred and it's really making me never trust apple with pcs again.

2. "I ran the system rescue cd and fsck'ed both partitions" -> Did you get any direct filesystem error message from the system?
3. What happens if you try to delete the corrupted files and restart ? Does it become corrupted too every time?
4."X sometimes won't start, I get a black screen and I need to power down by holding the power button." -> Which driver/kernel/xorg version do you use ? I've experienced such a situation with the nvidia-185.18.31 driver.
Thank you for your quick response.
1. Is it safe to delete the corrupted files in /var/log? I already deleted viminfo after it got corrupted the first time, but it happened again.
2. In the rescue cd, fsck quickly said "it's ok" without checking. Is there a way to force it to check? The man page doesn't say. The longer check I get sometimes when booting ("hasn't been checked in the last X mounts yadda yadda") shows only "fixed write time in the future" from time to time.
3. The Xorg.0.log particularly gets corrupted after the hard restart that I issue when X fails to start and a black screen locks up the pc.
4. xf86-video-ati is 6.12.2-2, kernel26 is 2.6.30.4-1. xorg-server: 1.6.3-2. The black screen issue will be (I hope) solved in the other thread I made (link in first post), but I have the suspicion that both problems are very closely related (one is the cause for the other, or some sort of vicious circle.)

IPod nano Software Download - Files are corrupt

Just purchased an iPod nano. Tried to install the software. When it reached the iTunes portion it flashed a message that "Some installation files are corrupt. Please download a fresh copy and retry the installation." I went to the website and did that. Results were the same. Ideas?

Itunes cannot run because some required files are missing...vista 64 bit OS

I'm running on a Vista 64 bit HP computer, and I have been trying to download itunes for the past couple days and all it says is Itunes cannot run because some required files are missing please reinstall itunes...I have no idea what to do...i have looked around the forums for information and I guess I'm not the only one having issues using a 64 bit OS. Btw the 64 bit Itunes won't work either. It does the same exact thing...

all it says is Itunes cannot run because some required files are missing please reinstall itunes
I'd like to check for malware with that message, Nico. (With modern versions of iTunes, if files really were missing, iTunes would be much more likely to do a repair install of itself when you wen't to launch it, rather than returning the old-fashioned files-are-missing message.
Download and install the free version of MalwareBytes AntiMalware. Update your MBAM definitions and run a full scan of the PC. (Takes about 2 hours on My Lenovo.)

After the scan completes, find the log file for the scan, and paste the contents of the log into a reply here.

ITunes can not run because some required files are missing.

I got a message that said something like "iTunes can not run because some required files are missing. reinstall itunes." I tried to reinstall iTunes but I kept getting that message. So, i uninstalled it, and tried to install it again. this did not work. I think that Quicktime is actually what is broken, because iTunes installs fine, but the Quicktime installation failed. When the installation failed, i got a message that said, "Installation failed: error code: -3"
I then tried installing Quicktime with the standalone installer. The installation got further, but it then failed as well, giving the error code -1603.
What can I do to get this reinstalled, and if you can't answer that, how can I contact Apple from Iraq? Thank you.

hmmm...that happened to me at one point to, and I'm trying to think back, I believe I was able to uninstall it by using the standalone installer.....
Try these steps and see if anything helps, and then in the troubleshooting section, look up the specific error number you are receiving...

ITunes 6.0.1 for XP wont install, says installation file is corrupt -

Is this the same error as other people have been getting?
It says Installation file is corrupt, download a fresh copy and try again.
Same error.
This is happening on my friends windows XP machine, it happened on my dads,(problem solved, dont know how??? just d/l it and it worked when i was trying to fix it before i did anything) and on a work mates.
Today, because of this, he formatted his pc, and put everything back on. He tried to install iTunes as soon as he possibly could, no luck. deleted any trace it left, and installed SP 2 etc all the updates. Still no luck. Exact same error.

hi Lee!
It says Installation file is corrupt, download a fresh copy and try again.
hmmm. this has been known to be caused by an nvidia firewall:
http://discussions.apple.com/click.jspa?searchID=-1&messageID=813136
... but if that doesn't seem to be relevant, you could also try downloading from the "QT + itunes" site:
http://www.apple.com/quicktime/download/win.html
... or using a different browser for the download.
if no joy with that, we could also try cutting the Gordian knot:

You should first uninstall iTunes completely.
This is not an easy task!
Read this article on how to remove iTunes completely
http://www.howtogeek.com/howto/23959/completely-remove-itunes-and-other-apple-so ftware-from-a-windows-computer/
Then download the latest version of iTunes for your Windows Version and install it.

I'm getting a message that says itunes cannot run b/c some required files are missing. Please reinstall itunes. I'm scared to, I don't want it to replace my current itunes and lose all my music!

Reinstalling iTunes simply replaces the application. It shouldn't affect your media. You do have backups, right?

Application files are corrupted. How do I reinstall application files?

I own the macbook Pro. My application files are corrupted. How do I reinstall them?

"Any more ideas?"
The point of my reply was for you to apply the 10.3.9 Combo Update over your installation. Repairing Permissions is always a good idea before and after any update or upgrade. Did you try this and still having Java problems/errors?
This will not harm anything to apply the Combo update over your OS.
You did not post which version of 10.3 you are using but you may wish to check to see if this Apple Knowledge Base article applies to your situation:

"This ipod cannot be updated. The files are corrupted and unreadable"

This message now appears when I connect my ipod to itunes....
"This ipod cannot be updated. The files are corrupted and unreadable"
The ipod still works and charges, but it will no longer let me add new files to it. The contents of my ipod are still displayed as usual on itunes, so it obviously is reading it to some degree. It advises me to run a chkdsk utility, but I have no idea how to do this.
Has anyone encountered a similar problem? Does anyone know how I can fix this problem?
Many thanks

If your iPod is corrupt then you have no choice but to restore it.
Before you do that, you may have some success getting the music off it and onto your hard drive again.
Check out the instructions/suggestions here.

Your application files are corrupted!

I recently purchased a new MacBook Pro. I also have a three year old MacBook Pro that the new one is replacing. When the new one was removed from the box, it was running fine. It also asked me some questions concerning it being a replacement, so I said 'sure' and it wanted me to run the Migration Assistant. So I ran the Migration Assistant for the next four hours.
When it was completed, it said everything was copied successfully. Now, whenever I log onto the new MacBook, I receive the following error message:
"Your application files are corrupted! For security reasons please reinstall the application." Then there is an OK button.
I have tried reinstalling the application files (I think). Also, it only happens when I logon. So, I made a new account thinking the account may be the problem, but the new account shows the same error message. I tried holding down the Shift key until the progress bar appeared, but still no luck.
The old MacBook ran, or still runs fine and error free. What is my next step?
Thank you.

Recovery Mode and reinstall.
Or erase and reinstall.

About TimeMachine backups and Recovery Mode
http://support.apple.com/kb/HT1427
http://www.apple.com/osx/recovery/
OS X Lion and later let you:
Start from OS X Recovery using your Time Machine backup disk. With OS X v10.7.3 and later, Time Machine backs up the Recovery System on your Mac to your backup drive as well. This lets you use your Time Machine drive to start up your Mac if needed.
OS X Recovery:
http://support.apple.com/kb/ht4718
OS X Internet Recovery
Mac models introduced after public availability of OS X Lion include the ability to start up directly from an Internet-based version of the OS X Recovery system. OS X automatically uses this feature when the Recovery System on the hard disk isn't available (such as when your hard disk encounters an issue, or when your hard disk has been replaced or erased). OS X Internet Recovery lets you start your Mac directly from Apple's servers. Starting up from this system performs a quick test of your memory and hard drive to check for hardware issues.
OS X Internet Recovery presents a limited interface at first, with only the ability to select your preferred Wi-Fi network and, if needed, entering a passphrase. Next, OS X Internet Recovery downloads and starts from a Recovery System image. From there, you are offered the same utilities and options as a local Recovery System.
Requirements for reinstalling OS X using Recovery
Reinstalling OS X using OS X Recovery requires broadband access to the Internet via Wi-Fi or an Ethernet connection. OS X is downloaded over the Internet from Apple when OS X Recovery is used for reinstallation
If you use Internet Recovery to reinstall OS X, it installs the version of OS X that originally came with your computer. After installation is finished, use the Mac App Store to install related updates or later versions of OS X that you have previously purchased.
