"iCal software cannot be installed on this computer"...why?

I deleted iCal a few months ago because there was something strange going on with it and I figured I'd just redownload it. Well, last week I finally got around to it and it keeps saying "iCal software cannot be installed on this computer." My software is all up to date so I'm about to pull out my hair in the process of figuring our why the heck it's saying that.
Does anyone have ideas of why this could be? Or should I just bring my computer in to my Apple store and have them figure it out?
Thanks so much for any help!!

Lauren Beth,
Welcome to Apple Discussions.
To reinstall iCal:
1. Insert the Leopard Installation disk into the computer.
2. The disk will appear on the desktop.
3. Double click on the "Optional Installs" folder.
4. Double click on the "Optional Installs.mpkg."
5. Click on (Continue) in Introduction.
6. Click on (Continue) in Software License Agreement.
7. Click on (Agree) to agree to the terms of the software license agreement.
8. Click on the disclosure arrow ▶ next to Applications.
9. Select (✓) iCal.
10. Click (Continue).
11. After iCal has been reinstalled, download and install the Mac OS X 10.5.8 Combo Update to bring iCal up to the most recent version.

The grey discs will only install on the model of Mac with which they shipped. If these discs didn't ship with your Mac, and they don't work with your Mac, well then there's not much you can do.
As far as it being legal or not, it is illegal to install this software on more than one Mac at the same time. If the original owner of these grey discs is no longer using the software and has removed the software from his system, and he has not retained other copies of it, then it is legal for him to transfer ownership of the software to you, and legal for you to use it. But that's not of much help to you if you don't have the correct model of Mac.
Get the black retail Tiger install disc from amazon.com or elsewhere. It will work on all Mac models with built-in firewire.

This Software Cannot Be Installed on This Computer

This seems to be a fairly common problem, but I haven't yet found a definitive solution. Basically, we decided to reinstall 10.4 on a couple computers (1.8 GHz iMac G5's) at work. It worked fine on the first computer, but it won't let us even install on the second.
The 10.4 disc is inserted, and the computer boots up fine, and takes you to the language select screen. However, once I hit continue, it brings me to the "Install Mac OS X" screen, and says "This software can't be installed on this computer" and gives me the option to Restart or choose a different startup disk (there aren't any others).
Now, we have a half dozen Macs here, and at least 3 sets of install discs. However, I've tried the three I could find (2 iMac G5 install discs, and one regular 10.4.4 disc) and they all give the same error. Should I keep looking for another install disc, or is the problem something else. Thanks!

Ah, right, I should mention that we already attempted an erase and install (I think... I wasn't here for that part). Either way, it won't even let me get that far. The only thing I can choose is the language. After that, it says "Preparing Installation" followed immediately by the Install window popping up, looking like it's going to work, then saying "The software cannot be installed on this computer."
The only things I can do from that point are choose the things in the Utilities menu. I've already tried repairing the disk. Any other ideas?

PowerBook G4 "this software cannot be installed on this computer"

Hello Everyone,
I recently bought a new MacBook Pro and I wanted to give away my Powerbook G4. I tried using the factory install discs to wipe as well as Mac OS 10.3 retail discs. I thought the hard drive have Mac OS 10.4 was a problem, so I wiped the drive and bricked my computer.
When I try to install Mac OS or use the factory install discs, it gives me the error "this software cannot be installed on this computer"
Does anyone know how to correct this?

If you have access to an Apple Store Genius, by all means.
By "too old" it's not that the disks age and go bad, but the installer checks what exact model you are trying to install onto. You get the error message if it's not a compatible OS and machine, such as the OS being older than the machine needs.
If there's no way your disks could have gotten mixed up with others, it's a mystery that someone with other troubleshooting tools (like a range of retail OSX disks) may have to figure out. Did you ever actually install OSX from these disks? Perhaps they were always wrong and you never knew it?

IMac says This Software Cannot Be Installed On This Computer

My iMac has just had a new HDD fitted and im trying to re install 10.4 on it and it comes up with "ALERT - This Software Cannot Be Installed On This Computer" what can i do?

1) You must use the either Original Tiger Install DVD set or a later Retail Upgrade Disc than came with that iMac?
2) The Partition Map Scheme of most off the shelf drives is normally Master Boot Record and it must also be changed to GUID Partition Table.
1. Boot from your install DVD, Upgrade Disc or Bootable Clone and open Disk Utility.
2. Highlight the new HD in the list of drives and select the Partition tab.
3. Under Volume Scheme select 1 Partition and click on the Options... button.
4. Select GUID Partition Table in the drop down window and click OK.
5. Set the Format to Mac OS Extended (Journaled) and click the Apply button.
6. Once thats done then you can do a clean Install, Restore your Bootable Clone.

Alert - This Software Cannot Be Installed On This Computer

I need your assistance. I have this refurbished iMac G5 that my father gave me several years ago. I believe he purchased it directly from Apple or from an authorized seller. I have all of the cds it came with. Long story short, I am trying to install the OS using the discs provided and it keeps cropping up with the alert message - This software cannot be installed on this computer. I have 2 gray CDs - it says it's iMac G5 Mac OS X Install Disc 1, Mac OS version 10.4, AHT version 2.5.1. I also have another disc that will go further along in the installation process but stops because I do not have OS 10.3 installed. This CD is black with an X and says Mac OS X Tiger Includes Xcode 2, CPU Drop In DVD, Version 10.4. I performed the Apple Hardware Test and everything passed. I tried partitioning it like other users have offered but it still comes back with the same message.
Your suggestions and assistance will be most welcome! Let me know if I should include any other details.

Hi,
I have all of the cds it came with...
I have 2 gray CDs - it says it's iMac G5 Mac OS X Install Disc 1, *Mac OS version 10.4*, AHT version 2.5.1.
I also have another disc that will go further along in the installation
process but stops because I do not have OS 10.3 installed. This CD is black with an
X and says *Mac OS X Tiger* Includes Xcode 2,
Something is not right -
If gray discs marked 10.4 really did ship (or were supposed to ship) with your computer, then you would *already have* a Tiger version, and there would be no role for the Tiger upgrade DVD. In fact if your computer really is a model that came with Tiger originally, then you couldn't now install Panther on it even if you had Panther install discs.
I believe that the iMac G5 model that came with grey 10.4 Tiger discs was the 2005 "Ambient Light Sensor" (ALS) model. To be sure you have that model, you can obtain its serial number from the base of the computer as shown on [this page|http://support.apple.com/kb/HT1749] and then plug the last 3 characters into the identifier box on [this page|http://www.everymac.com/ultimate-mac-lookup].
What model did it report? If your iMac is not an "ALS" model, then you probably have the wrong original install discs. If you do have that model, then perhaps the HD was not formatted correctly before you tried the install. Let us know.

Yes, I'm using the gray 2 disc set of Lepoard, full version, and yes I chose the GUID type partition.
Do you know what the error log messages mean? or how to fix it so it will install as now I have nothing. I don't have any Tiger disks to go back to because I got my Mac Mini used.
Any help is greatly appreciated. Thank You, Jill
It sounds as if the CD set you have is not for the computer you purchased. Each CD set is made specifically for the computer for which it ships with. That CD set will not work on any other computer.

"This software cannot be instaled on this computer."

I am attempting to install tiger onto a Macbook Pro. These are the install disks that came with the mac, but it says that they cannot be installed on this computer. Any Ideas?
The disk says:

Thanks

I seems to be a serious problem to install tiger on brand new allu imacs or macbooks pro. I spent two afternoons working with two different apple care experts without getting a satisfactory solution. They will let me know a solution soon!!!
The closest you can get is the following: 1) partition the HD of the allu imac using leopard tools, 2) start the allu imac using target modus, 3) connect an white intel based imac and allu imac with firewire cable, 4) start the white imac and install in the tiger partition os x tiger -at least 10.4.7; 5) restart the allu imac with the alt key and the tiger volume; 6) install imac software update 1.2.1 (tiger); 7) upgrade to 10..4.11.
That is the far you can go. The drawback is, you can use only airport in your network, the built-in ethernet interface cannot be configured. May be, this can help you in the meantime.

Software cannot be installed on this computer

Hello all
I've been looking around this forum for a while now and have found similar problems to mine but there haven't been any exact answers to my question
I was horsing around with my computer and managed to somehow foul up my btree on my internal hard drive rendering it useless. No fear, wiped the drive, popped in my grey installation disk that came with my computer which I bought from Apple. None of this eBay stuff. I get the ever popular Alert...You cannot install this software on this computer message.
I understand that the grey bundled discs are computer specific, and as previously stated, are in fact the ones that came with my computer. So my question is whether or not they are tied directly in to the hardware that the computer was shipped with.
I pulled my mini apart and upgraded the memory about two years ago. I found someone that commented that the bundled OS X installation DVD didn't work on his computer because of that same fact. But someone else immediately responded and shot that down, saying that upgrading your computer memory won't hinder the OS X installation.
let me know what you think

Mac Mini 1.42 Ghz G4 Mac OS X (10.4.7)

There is no connection between the OS X installer discs and the specific computer, only with the specific model. Installing OS X is also unaffected by how much RAM is installed or even if the RAM was upgraded as long as the amount of RAM installed meets the minimum required for the version of OS X being installed.
If you were able to boot the computer from the OS X Installer Disc, then you can install OS X. What you may need to do is re-prep the hard drive:
Extended Hard Drive Preparation
1. Boot from your OS X Installer Disk. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Installer menu (Utilities menu for Tiger.)
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. Otherwise, click on the Partition tab in the DU main window.
3. Set the number of partitions from the dropdown menu (use 1 partition unless you wish to make more.) Set the format type to Mac OS Extended (Journaled, if supported.) Click on the Partition button and wait until the volume(s) mount on the Desktop.
4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
5. Set the format type to Mac OS Extended (Journaled, if supported.) Click on the Options button, check the button for Zero Data and click on OK to return to the Erase window.
6. Click on the Erase button. The format process will take 30 minutes to an hour or more depending upon the drive size.
After formatting has completed quit DU and return to the installer. Proceed with the OS X installation.

Error message "this software cannot be installed on this computer" - itunes

I had used this software called "uninstaller" like a "Yank" file, to uninstall my old itunes due to computer problems.
I had also used my software restore CD to reinstall my old itunes 3 back. Right now, I have downloaded the newest itunes to upgrade my itunes, at the start of the installation page, error message above appears.
I have the right requirements for ver itunes 6. I have a G3 800Mhz ibook, Mac OS X 10.2.8. Why does error message appears? What can I do to solve this problem? Reformatting my com is the least i want to do...again...
Any help will be very much appreciated....thanks!

Are you using a retail 10.5. upgrade DVD or did you borrow the 10.5 DVD from another Mac? Also please check to see if your iMac meets the minimum requirements for 10.5 which are:
Mac OS X v10.5 Leopard requires:
A Mac computer with an Intel, PowerPC G5, or Power PC G4 (867 MHz or faster) processor
512 MB memory or more
A DVD drive for installation
9 GB of available disk space or more
Some features require a compatible Internet service provider, fees may apply.
Some features require Apple's MobileMe service; fees apply.

Powerbook 6,7 (ibook g4?) hard disc died. Installed new disc. Ibook G4 restore disc (v10.4) produces error " This software cannot be installed on this computer" what can I do?

I formatted the drive using the disk utility and restarted and it still gives the same message.

Boot from the restore disc and select Disk Utility from the Installer or Utilities Pull-Down menu. Take a look in Disk Utility near the bottom when you have the drive (not the Volume under the drive) selected. Is the Partition Scheme listed as Apple Partition Map?
If not, then you need to correct that by selecting the Partition tab, click "Options" and click the Apple Partition Map radio button, then click the "OK" button and then click the "Partition" button on the DU window. If you didn't have APM at the beginning of this exercise, that should solve the problem.
Your 6,7 should be either this machine or this one.

Leopard won't install on Core Duo - "Cannot be installed on this computer"

Hi,
I have a white MacBook 2GHz Intel and took from a friends black Macbook 2.2GHz Leopard DVD's to install since he will use a mac for Vista. When I try to install it I get a message "This software cannot be installed on this computer" !!! I was surfing on the net but this is usualy problem with old mac's but I cannot believe that my NB is not supported ?!?! Can anyone help ? Also, Apple Hardware Test from Leopard DVD's is giving the same message.

No they are not. 10.5 OS/X install disks are universal. They will not mention MacBook on them. You can not use these CD's on another machine for two reasons: first they will not work. second: it was a license violation for them to be given to you.

Leopard Mysteriously "Cannot be installed on this computer"

I've been trying to install Leopard on my (slightly used) Intel MacBook since last night over and over. Every time I boot and start the Leopard Installer, the first thing I see is a window that says "This software cannot be installed on this computer". I've checked all over the internet and my computer and everything (to my knowledge, and patience) is up to date. I have absolutely no idea why this installer just doesn't want to work. I'm installing Leopard from my father's installer disc "1" that came with his MacBook Pro. I'd like to get this all done before my personal deadline (January 7), so if anyone could help me out (quickly!), it'd be greatly appreciated.
Thanks,
R_P.

"Federico_82" is correct. The gray disks that are shipped with the computer can only be used on the computer they shipped with and will not run on any other machine. You need to purchase the "Retail" version of 10.5 to install it on your machine.

This software cannot be installed on the computer/sibling link error

I have been helping a friend overseas troubleshoot her computer.
http://discussions.apple.com/thread.jspa?threadID=1741148&tstart=0
We are at the point where she was able to get her data off the drive and would now like to reinstall her system.
She has a refurbished iBook which was running 10.4.11 with software updates. Her startup disks are in the states as she is in a village in Africa. She has borrowed disks which contain 10.4.8 and is receiving the message that +"This software cannot be installed on the computer."+ Would this be due to different versions and trying install an older OS onto a computer with a newer OS?
She had a sibling link error on her hard drive, so we were able to recover data. I was hoping to reformat her hard drive to remove the error and reinstall the system. Would this error effect the installation process?
Thank you.

If this is an iBook model she will need to use a retail Tiger installer or the discs that came with her computer. She could try with Leopard if the iBook meets the requirements:
System requirements
You must have a Macintosh computer with:
an Intel processor or a PowerPC G4 (867 MHz or faster) or G5 processor
a DVD drive
built-in FireWire
at least 512 MB of RAM (additional RAM is recommended for development purposes)
a built-in display or a display connected to an Apple-supplied video card supported by your computer
at least 9 GB of disk space available, or 12 GB of disk space if you install the developer tools

I understand, while you may have knowledge with PCs you don't have the diagnostic tools available to you to professionaly diagnose a Mac. Apple does not make those tools available for the general public, they are only available to Apple and AASPs. To install the OS on the machine you need to locate the original 10.5.x install disc that shipped with the machine and insert it into the SuperDrive. Below are Apples instructions for setting up the machine:
Turn on the computer.
Insert the Mac OS X Install DVD into the optical drive, or insert the MacBook Air Software Reinstall Drive into the USB port.
Restart the computer.
Press and hold the "C" key while the computer starts up. The computer will start up using the Install media. Alternatively, press and hold the Option key at startup to select the volume containing the installer.
If your are using a wireless mouse, a mouse icon should appear asking you to turn the mouse on so that the computer can discover it.
Select a language, then press the right arrow key.
Click the Utilities menu, the choose Disk Utility.
Select a volume to erase (usually called Macintosh HD).
Click the Erase tab.
Click Erase... Important: This step will completely erase your hard drive. If you have installed Microsoft Windows using Boot Camp, or have multiple partitions, this procedure will erase the partition you select.
A dialog box appears asking if you want to erase the partition: click Erase.
After the partition is erased, choose Quit Disk Utility from the Disk Utility menu.
Part Two: Installing the operating system
When the Mac OS X Snow Leopard Installer screen appears, click Continue.
When the license agreement appears, click Agree.
Select the disk you erased. It should now be highlighted with a green arrow.
Click Install. A status bar appears on the bottom of the screen while Mac OS X installs.
An Additional Information screen appears, advising you that you operating system has been installed. Click Continue.
An Install Succeeded screen appears. Click Restart.
Part Three: Completing the Mac OS X Setup Assistant
When the restart has completed, a welcome video plays, then country/region selection screen appears.
Select your country or region and click Continue.
Select a keyboard layout and click Continue.
A migration screen appears. If you wish to migrate your data from another Macintosh, see Migration tips and tricks. If you do not wish to migrate, or want to migrate later, select "Do not transfer my information now" and click Continue.
A Wireless Service screen appears if you have wireless services available within range of your computer. Select "On" and click Continue.
If the network is password protected, you be asked for a password when you select it. Type the password and click Continue.
An Apple ID screen appears. This is used to purchase content from the iTunes store. When complete, click Continue.
