Lion OS Downloaded but Not Installed???

Downloaded Lion OS to MacPro. Rec'd install prompt, agreed to terms and hit install/continue. It was not installed. How do I find it to install again. App store says downloaded and no option to re-download. I had/have OS 10.6.8 installed.

How do you know it isn't installed? Select About This Mac from the Apple Menu. What OS version is displayed?
If the installer wasn't deleted then you will find it in the Applications folder.

How to download but not install OSX Mountain Lion on Mavericks

Hi all
I would like to download but not install OSX Mountain Lion on my MBP which is currently running OSX Mavericks.
This however seems impossible. I think OSX Mavericks were already installed on my MBP and therefore it seems "impossible" to download it.
Now, why would I to do this? The answer is quite reasonable, due to certain demands related to an application portfolio I need Mountain Lion, because the portfolio is not upgraded to run on Mavericks. And, it is more reasonable to downgrade a version of OSX, rather waiting for the portfolio upgrade which can take years.
Yes, I need to downgrade my secondary MBP which also came with preinstalled Mavericks. This can be done, if I only could download but not install Moutain Lion.
It should be easy enough; download Mountain Lion, make an installer and make a bootable thumb usb stick. Then erase Mavericks and install Mountain Lion.
I have previously bought Mountain Lion so it is accessible to me in the App Store, but whenever I try to hit the Download button, I get a message saying this can't be done, since I am running Mavericks.
This bugs me, it should be obvious users needs the flexibility to swap whatever OSX version they need. It is still software.
So, how can I download but not install Mountain Lion on my newer MBP that came with preinstalled Mavericks?
I would like to see answers like:
"In order to get this to work, you first have to disable the locking mechanism in [...] " instead of "No, this is impossible to do"
Regards

Thanks for your reply Eric
Can't help wondering thought, people are ok with this?
Basically Apple are saying: "Do not attempt to install an older version of OSX which came preinstalled. If so, expect multiple failures." Really?! Has it always been so? For me it's not like I'm going to install Snow Leopard on my Late 2013 Retina MBP, but I would expect some form of backward compatibility between the previous version and it successor. Apparently this is not possible, and how is this even acceptable?
Personally, I am not going to downgrade, as if I had a choice, but I would and I expected however, the possibility to at least download the previous OSX version. What do you do if you have bought several applications, not necessarily online from App Store and buy yourself a new Mac with preinstalled Mavericks and after installing your "old" applications they fail to work properly? What do you do since downgrading apparently is not an option. So... again, what do you do?
If you don't have friends with an older Mac, you could be facing serious problems. And I'm not talking about gaming, but serious business.
I find this quite disturbing actually, and please tell me it's not so. There gotta be a way to do this?
I simply want to download the OS but I expect some registry values (like windows' registry) keeps preventing this.
It should be possible to simply download and not download and install in one operation, shouldn't it?
Regards

Hi Thomas, I was trying to drag it from the Launch Pad where it just bounced back again. Have now solved it by dragging it from the Application.
Thanks.

Downloading but not installing Mountain Lion?

I have a MacBook Pro with Retina display purchased since June 11 so I qualify for the free upgrade to Mountain Lion. I understand that I have 30 days to get the software for free once it is released. On the other hand, I would like to wait before installing the software until 10.8.1 or 10.8.2 are released to let some of the bugs be ironed out first. Is it possible to download ML but not install it (within the 30 day period)?

I would do as stated above except that I would set the install location to an external drive and then when the download finishes disconnect the external.
The reason for this is you may not have the option to NOT reboot the system after the download finishes. And even if you do have that option at the time the download finishes the next time the system reboots it may be set, in the EFI system or through some command placed on the hard rive, to start the install automatically.
At this time no one really knows how Mountain Lion will react when downloaded from the Mac App Store.
Also putting the download on an external drive allows to to actually install it to that external and run it from there to check it out before you do the install on your internal drive.

HT201210 My download for iOS 7 was interrupted, it has downloaded but not installed. it goes through routine Terms & Agreements and everything, but when i try to update it tries to verify the update then says that the update is not available.

I dont understand, when i try to update it will go through routine apple stuff, then it it will say " Software Update Unavailable (under) Software Update is not available at this time. Try again later." The thing is that i was downloading it and my wi-fi had restarted for some unknown reason and it downloaded onto my phone but not installed. and at the moment it is really bothering me because I have waited a long time for iOS 7 and I am not being allowed to update my phone to it and i just wanted to know how to fix it. Thank you.

I imagine a ton of people are attempting to download it right now. Simple patience, maybe keep trying, and if possible, try a little later. Think of it as all those people lining up at Apple Stores + about a million more.

Why can I download but not install Mavericks?

My Macbook Air will download 5 programs associated with Mavericks but will not install them. I get an error message that reads, "unable to install due to unexpected error". Help please!

Launch the Console application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Console in the icon grid.
Select
/var/log ▹ install.log
from the hierarchical list on the left. If you don't see that list, select
View ▹ Show Log List
from the menu bar. Then select the messages from the last installation or update attempt, starting from the time when you initiated it. If you're not sure when that was, click the Clear Display button in the toolbar of the Console window and then try the installation again.
Copy the messages to the Clipboard by pressing the key combination command-C. Paste into a reply to this message (command-V).

I want to download, but not install Mavericks.

I am not quite ready to upgrade to Mavericks, but would like to download it and not install it. I might install it on an external drive first, if that is possible. It appears to be a 3.5 hour download for me. Can I just start the download process and leave it? I am afraid it will automatically install if I don't catch it at the end of the download process. Thanks!
iMac 10.6.8

The 10.9.3 version of the installer is version 1.3.42. Use, "More Info'" Cmd-I to see that. If that is what you have, re-downloading should replace the previous one with the newer version.
I'm downloading the 10.9.4 version now and will post back its installer version number.
Okay, 10.9.4 installer version is 1.3.44.

I can download but not install iTunes 10.5 on my Win 7 computer

How can I install iTunes 10.5 on my Dell Windows 7/64 bit computer? It downloads but will not install- all kinds of error messages... AND I can't use a new iPod touch (4th gen) with iOS 5 presumably pre installed w/o 10.5 on the Windows 7 PC!!!!

Hi again! Fixed it myself, but here's what I did (in case anyone else encounters the same problem):
Control Panel > Programs and Features > Add or Remove Programs
1. Uninstall iTunes (if you're upgrading, but if it's a fresh install, disregard this step)
2. Uninstall Apple Mobile Device Support
3. Uninstall Apple Application Support
4. Uninstall Bonjour
5. Repair Apple Software Update. If you can't, try uninstalling. I couldn't uninstall or repair mine (the same error message appeared) so I used Microsoft Fixit Engine (http://support.microsoft.com/mats/Program_Install_and_Uninstall) to uninstall it.
6. Download the iTunes installer and run it. Voila!

Mountain Lion downloaded, but not installed.

I recently download Mountain Lion, but when the download finished, I recieved an error message saying "Product could not be installed. Check your internet connection." My internet connection was actually working fine. I would like to try and download again, but that would mean paying again, and I don't want to do that if I don't know for sure if it's going to work.

Check that your computer is compatible with Mountain Lion.
To check the model number hold down the option/alt key, go to the Apple menu and select System Information.
Mac Pro (Early 2008 or newer) model number 3,1 or higher
Your Mac needs:
OS X v10.6.8 or OS X Lion already installed
2 GB or more of memory (More is better)
8 GB or more of available space

Flash Player 10 will download but NOT install on Mac (10.4.11)

I have a MacBook Pro that has all of the necessary ingredients to run FP 10 (unless it requires Java, which also won't install - does the same thing that I am about to describe FP 10 doing)...I can download it, but as soon as I double click on the FP 10 icon, nothing happens. I don't get any install instructions, nor do I get an error message.
Is there something that I am doing wrong? Is there something I should be using to open the application prior to installation? This is really ticking me off, and I have had the same problem with the docx converter....

After upgrading to 8.0.1 Firefox will download but not install extensions after upgrading to 8.0.1

Windows Vista. Avast Antivirus with Sandbox feature.
Outside Sandbox - all extensions available. Within Sandbox - no extensions available and not able to install any extensions. ie Adblock Plus, No Script etc.
Before upgrading to 8.0.1 no problems in either mode. Add-ons appear to be intact in either mode.
When attempting to install an extension after downloading:
"(extension) could not be installed because Firefox cannot modify the needed file".
Reluctant to delete pluginreg dat file because all extensions are working outside Sandbox.

Hi,
You may have to "trust' the upgraded Firefox, if there is such a setting in Avast and install extensions after starting Firefox outside of the sandbox - normally. Not sure about Avast, but usually a sandbox would mean a virtual area like hard disk storage, registry settings etc. for the sandboxed app and once the application is closed or the computer is shutdown, everything that was done by the app or via the app is sort of vaporized and the application and it's settings are returned to it's previous permanent state.

ITunes will download but not install

I am trying to install the latest version of iTunes for Windows. I can successfully download the file, but it won't install because Windows Installer keeps trying to look for the files on a different drive that is no longer operational. How can I install the update?

Hey DrRuss,
Usually issues installing iTunes on Windows can be resolved after going through these troubleshooting steps. If one step does not resolve your issue, proceed to the next:
