i downloaded reader 11.3 ,do i need to uninstall older versions ?

If you have Reader 10.x or 11.x installed, there is no need to uninstall. Older, or much older versions should be uninstalled before installing a much newer version.

Do I need to uninstall older version of Photoshop first?

Nowhere in the FAQs or Install instrucitons, either the text or video install instructions, can I find any reference to the need or lack of the need, to uninstall an older version of Photoshop prior to downloading and installing the newer version. Specifically I will be upgrading from CS2 to CS5.
Should I then assume it is not necesary? And if so would it be wise once the upgrade is done, that then I should uninstall CS2?
Thanks
Forgot to mention I am using an older but competant desktop which funtions fine using CS2. Windows 32 bit, XP Sp3 Home Edition, 2.56GB RAM.

There is no need to uninstall CS2 before or after. You might find that some things are easier to do in CS2, creating PDF presentations etc. (now moved to Bridge)

Lightroom - do I need to uninstall older versions?

if I have photoshop lightroom 4.3 installed, do I have to uninstall lightroom 2.7
Message was edited by: Victoria Bampton - title changed to make it more descriptive

No, you don't have to.
Both versions can co-exist on your computer.
But keep in mind that Lr 4.3 updates the catalog created by Lr 2.7 (in fact it creates a copy of the catalog and updates the copy). Lr 2.7 is not able to read the Lr 4 updated catalog.
If you try to open it with Lr 2.7 you will get a message saying that this "catalog is too new".
Because Lr 2.7 cannot read the Lr 4 catalog I would recommend that henceforth you do your editing in Lr 4.3 only and use Lr 2.7 only to check things out (Lr 4 is quite a bit different than older versions).
If you would edit in both versions you would get two ever more diverging catalogs.

Many thanks.
Unfortunately, this sort of trouble has gotten more complicated to deal with ever since Microsoft pulled the Windows Installer CleanUp utility from their Download Center on June 25. First we have to find a copy of the utility.
Let's try Googling. (Best not to use Bing, I think.) Look for a working download site for at least version 3.0 of the Windows Installer CleanUp utility. (The results from mydigitallife and Major Geeks are worth checking.)
After downloading the utility installer file (msicuu2.exe), scan the file for malware, just in case. (I use the free version of Malwarebytes AntiMalware to do single-file scans for that.)
If the file is clean, to install the utility, doubleclick the msicuu2.exe file you've downloaded.
Now run the utility ("Start > All Programs > Windows Install Clean Up"). In the list of programs that appears in CleanUp, select any QuickTime entries and click "Remove".
Quit out of CleanUp. Restart the PC, and try another iTunes install. Does it go through properly this time?

Cannot install Adobe Reader 11.0.09 and Asian Fonts over older versions

I'm using a script to install Adobe Reader 11.0.09 and it works sometimes, but very often, there is an error saying it cannot install it because a previous version exists.
We have to manually uninstall older versions of Adobe Reader 11 and then re-run the script and then it works.
@echo off
cls
start /wait msiexec.exe /i \\appserver1\Apps\AdobeReader\11.009\AcroRead.msi /qb TRANSFORMS="\\appserver1\Apps\AdobeReader\11.009\AcroRead.mst"
start /wait msiexec.exe /i \\appserver1\Apps\AdobeReader\11.009\fonts\FontPack11009_XtdAlf_Lang.msi /qb
How can we change this script so that it will force installation over any previous version?
By the way, the installation was created with Adobe Customization Wizard and has settings enabled to remove any previous versions of Adobe Reader. So, the problem with installing over existing version could be from the Font Pack installation,

What does the verbose installation log say?

DO I need to Uninstall Prior Version of Reader to Install Udated Version

Hello, I am running a Dell XPS with Vista Home Premium. The PC came with Adobe Reader 7.0. When I try to run it, message states there is a compatibility issue between Vista and that version of Reader. I want to upgrade to 8.1.2 but would like to know if I need to uninstall the older version first before downloading and installing the newer version?
Also, I noticed a lot of people with problems installing 8.1.2. Is this version safe to install and use on Vista?
Thanks very much.

You don't need to delete the previous Logic Pro version before installing Logic Pro X. Logic Pro X is a new version and won't replace the old Logic Pro version, so if you like Logic Pro X and that's what you need after testing it, remove the old Logic Pro

Hi, my computer's too old to download 3.6.24 and it says that the older version will stop being supported soon, so how can I continue to use Firefox, I can't afford a new computer? It crashes a lot too, I've been told that's because it's old too.

It seems to crash after a period of time and then will keep crashing constantly if I keep trying to open up Firefox. It does the same with Safari. It's a mac running on 10.5.8. Is it possible to download and use older versions of Firefox? Help! Please.

There are some recovery programs out there if you google them - many with free trials. I haven't tried them so I have no opinion.Read any professional tech and user reviews you can find before you try one. I have read here in the past that some have worked for people who have posted here.
To help in the future, have you considered using Jump Desktop - Remote Desktop? I know it won't solve the problem you're dealing with now (unless notes were taken on your computer.) It's in the app store. It's the #1 paid app in the business category and the reviews are great. It allows you to see anything that's on your computer on your ipad. If you take your notes on your ipad then you might want to email them to yourself, put them on Word in your computer, for example, and then if you need them in class, you remotely connect your ipad to your computer and you will see your notes. This way you won't have to rely so much on the cloud. The explanation would be too long here, but you might want to take a look at it. You can use the free trial on jumpdesk.com and then if it works for you, buy it in the app store.
Meanwhile, it's hours since you sent this post. Hopefully others who can help solve your problem who are on this forum now can help you. I hope you get your notes back. Don't give up too quickly.
Hope this helps.

Need to reinstall older version new one does not support finger scanner

I updated to newest version how can i download older version that supported associated dpql files

Google Toolbar doesn't support newer versions of Firefox because Google decided that its functionality was mostly built into Firefox itself now or otherwise available via a Firefox addon:
* http://googletoolbarhelp.blogspot.com/2011/07/update-on-google-toolbar-for-firefox.html
Google provides the following help article on the topic:
* http://www.google.com/support/toolbar/bin/answer.py?answer=1342452&topic=15356
Note that Firefox 4 is not supported by Mozilla anymore. To get the required security and stability updates, users need to install the later Firefox updates (currently Firefox 7..0.1).

Need applescript studio older version

I have been asked to program for a company. what I would like to do is go back to an older version of Applescript studio what actually uses Applescript so I can create on interface with drop down windows and that cool floating gray-ish window. I dont know Obj-C.
what version of AS would that be. thanks for the info.

AppleScript is a set of system components, so you can't just drop in an older set.
AppleScriptObjC does use AppleScript, the main difference is in the way it accesses the Cocoa frameworks - AppleScript Studio essentially uses a bunch of terminology and handler wrappers around Cocoa methods that the Studio development team have gotten around to including, while ASOC can call Cocoa methods directly (a bit cleaner than Studio's call method kludge). You don't really need to know Objective C, but it does help a little when looking at the documentation - I know just enough to get an idea what some code snippet is doing, but don't ask me much more than that.
Older AppleScript Studio projects can still be edited and compiled in Snow Leopard's Xcode, so the components are still in there. Since Apple wants everyone to start using the new framework, the older project templates have been removed, but they can also still be used. If you really need to develop a new Studio application, for example to use on older systems, you just need to do a couple of things.
1) The AppleScript Studio palette can be enabled in Interface Builder by using defaults write com.apple.InterfaceBuilder3 IBEnableAppleScriptStudioSupport -bool YES
2) You need to get a copy of an AppleScript Studio project template. If you have access to a Leopard system installation, the easiest way would be to make a copy of the desired template from the */Developer/Library/Xcode/Project Templates/Application* folder there, for example the *AppleScript Application* template (you can also download the old templates from my iDisk here). You probably shouldn't modify anything in the /Developer folder, but you can use custom project templates from your user's *~/Library/Application Support/Developer/Shared/Xcode/Project Templates/Application* folder, so copy your project template there (make intermediate folders as needed).
Once the template is copied, you can select it when making a new project and use the old terminology as usual.

Do I need to and how to uninstall older version of JDK 7.0

Hi,all I have installed both JDK 1.7 update 21(1.7.0.210) and 51(1.7.0.510), and so I wonder do I need to uninstall the older version which is JDK 1.7 update 21, as they both show up in the list of `Programs and Features` on Windows. Second, I tried Java Uninstall Tool, it only reports `There are no older versions of Java on your computer`. So I wonder can I just use the `Programs and Features` that manually uninstall any version of Java if I need to.
cheers

As I also set up `JAVA_HOME` to `jdk1.7.0_21` when I tried to install Android Developer Kit, so do I need to update `JAVA_HOME` accordingly? The installation was tricky, and I don't know if it is this setting up `JAVA_HOME` step made the ADT installation work.
If the installation instructions of this product require setting a JAVA_HOME variable then yes, otherwise no.
Trying is certainly a good teacher, but I'd rather read documentation first to at least make it educated tries.

Do I need to uninstall previous version of Firefox before installing new version?

I am worrried about installing new version (3.6.13 ) since old version (3.0.15) is working o.k. Can you advise?

When you install a release version of Firefox (current version is 3.6.15), it will by default replace the existing version. There is no need to uninstall the old version first.
