CS6 Error 16 Code after installing on new computer.

I just purchased a new Mac Pro Desktop. My old machine used Snow Lepoard and this is Mountain Lion. After migrating data from my ole machine to this one, I am unable to open any program in CS6. When I attempt to, I receive a Error 16 advising me to uninstall and reinstall the software. This would result in a couple of years of up-dates, etc. How can I correct this problem?

please review your installation logs for specific error messages which may have occured during the install process. You can find details on how to review the install logs at Troubleshoot with install logs | CS5, CS5.5, CS6 - http://helpx.adobe.com/creative-suite/kb/troubleshoot-install-logs-cs5 -cs5.html.

Acrobat X Pro won't open at all after installing on new computer. Please help! It is from the CS6 Suite

Hi, Can anyone help me? I had to change my computer, so I re-installed my whole CS6 Suite. Everything works except my Acrobat X Pro... It won't even open!! I am using a Windows 7 PC ... I even had Dell try and help me... the only thing they where able to do was help me be able to see .pdf docs in Reader! But I can't open a document, or create one, block sensitive info, nothing!

Hi Lisley56, I found the solution there is a Plug in for Acrobat X Pro that came with Adobe Suite CS6... I downloaded it and that did it!!! It's called "Acrofix". Try looking it up in the Adobe website!!! I hope it works!!

After installing a new computer, we added firefox and I was wondering if there is a way to restore my gadgets that I had before in a simple way.

I had gadgets like local weather, moon phases and Chicago Tribune.
Do I have to search for them again or can I get them back easily on the home page?

The only OSX update that you have available is Snow Leopard (10.6) which you can purchase from the Apple online store and it comes on a disk. In order to install subsequent OSX's such as Lion, Mt. Lion and Mavericks (which can be downloaded and do not require a disk) it requires that the MBP have 10.6.8 installed.
That of course assumes that your unidentified MBP qualifies for those operating systems.
In short, to proceed any further, you will have to accommodate Snow leopard.
Ciao.

Also, I am wondering if you have any tips to speed up streaming speeds on videos without installing an update. I can no longer watch Netflix or Hulu due to how slow my computer streams videos now. Besides updating my Mac, is there any way to solve this? What may be causing this issue?
In regard to the above, please read this article:

After installing a new version of Firefox, I get the error message "The procedure entry point JS_GetOperationLimit could not be located in the dynamic link library js3250.dll" when I try to start firefox. Elsewhere in the forum a complete reinstall is suggested; however, I can't do that because of my company's IT policies. Is there any way to solve this problem WITHOUT a complete reinstall? Thank you!

If you can't reinstall Firefox yourself then you need to contact your IT department and ask them to check the Firefox installation.
It is possible that some files got broken with the latest update.

i see that i have a problem after installing my new hard drive on my macbook pro mid 2009 version. I put a new hard drive, with all of my information from my old drive installed on it, into the computer. but now have the blinking question mark folder. I see that it means that it isn't reading the new hard drive.
did i miss a step between transferring all of my information from my old hard drive to the new hard drive and installing the new hard drive into the computer. I believe that i installed properly. it was quite easy.
thanks for your help

It means there is no bootable system on the drive. If you still have access to the old drive, then I suggest you boot from it then clone it to the new internal drive. Use OPTION boot to boot from the Recovery HD on the old drive:
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
     1. Select Disk Utility from the main menu then press the Continue
         button.
     2. Select the destination volume from the left side list.
     3. Click on the Restore tab in the DU main window.
     4. Select the destination volume from the left side list and drag it
         to the Destination entry field.
     5. Select the source volume from the left side list and drag it to
         the Source entry field.
     6. Double-check you got it right, then click on the Restore button.
Source means the external old drive. Destination means the new internal drive.

... With the latest software updates for OS X, I've read that anti-virus software is largely superfluous for Mac. Any opinions to the contrary/negative experiences?
Almost. Anti-virus software is completely superfluous for Mac.
I have tested most of the commonly available Mac "anti-virus" products under controlled conditions. The only differences between them are their varying degree of worthlessness. Some are malicious and will corrupt your Mac. The vast majority of Mac problems reported on this site are the direct result of using such products.
OS X already includes everything it needs to protect itself from viruses and malware. Keep it that way with software updates from Apple.
A much better question is "how should I protect my Mac":
Never install any product that claims to "speed up", "clean up", "optimize", or "accelerate" your Mac. Without exception, they will do the opposite.
Never install pirated or "cracked" software, software obtained from dubious websites, or other questionable sources. Illegally obtained software is almost certain to contain malware.
Don’t supply your password in response to a popup window requesting it, unless you know what it is and the reason your credentials are required.
Don’t open email attachments from email addresses that you do not recognize, or click links contained in an email:
Most of these are scams that direct you to fraudulent sites that attempt to convince you to disclose personal information.
Such "phishing" attempts are the 21st century equivalent of a social exploit that has existed since the dawn of civilization. Don’t fall for it.
Apple will never ask you to reveal personal information in an email. If you receive an unexpected email from Apple saying your account will be closed unless you take immediate action, just ignore it. If your iTunes or App Store account becomes disabled for valid reasons, you will know when you try to buy something or log in to this support site, and are unable to.
Don’t install browser extensions unless you understand their purpose. Go to the Safari menu > Preferences > Extensions. If you see any extensions that you do not recognize or understand, simply click the Uninstall button and they will be gone.
Don’t install Java unless you are certain that you need it:
Java, a non-Apple product, is a potential vector for malware. If you are required to use Java, be mindful of that possibility.
Disable Java in Safari > Preferences > Security.
Despite its name JavaScript is unrelated to Java. No malware can infect your Mac through JavaScript. It’s OK to leave it enabled.

Popup windows are useful and required for some websites, but popups have devolved to become a common means to deliver targeted advertising that you probably do not want.
Popups themselves cannot infect your Mac, but many contain resource-hungry code that will slow down Internet browsing.
If you ever see a popup indicating it detected registry errors, that your Mac is infected with some ick, or that you won some prize, it is 100% fraudulent. Ignore it.
Ignore hyperventilating popular media outlets that thrive by promoting fear and discord with entertainment products arrogantly presented as "news". Learn what real threats actually exist and how to arm yourself against them:
The most serious threat to your data security is phishing. To date, most of these attempts have been pathetic and are easily recognized, but that is likely to change in the future as criminals become more clever.
OS X viruses do not exist, but intentionally malicious or poorly written code, created by either nefarious or inept individuals, is nothing new.
Never install something without first knowing what it is, what it does, how it works, and how to get rid of it when you don’t want it any more.
If you elect to use "anti-virus" software, familiarize yourself with its limitations and potential to cause adverse effects, and apply the principle immediately preceding this one.
Most such utilities will only slow down and destabilize your Mac while they look for viruses that do not exist, conveying no benefit whatsoever - other than to make you "feel good" about security, when you should actually be exercising sound judgment, derived from accurate knowledge, based on verifiable facts.
Do install updates from Apple as they become available. No one knows more about Macs and how to protect them than the company that builds them.
Summary: Use common sense and caution when you use your Mac, just like you would in any social context. There is no product, utility, or magic talisman that can protect you from all the evils of mankind.

Old computer died and I am trying to install Illustrator CS5 on new computer.
Last version I had before CS5 was/is Illustrator 10,which has been installed on new computer.
CS5 install says I need CS2,3 or 4 before installing 5, but old computer went directly from 10 to CS5.
How can I repeat this 10 to CS5 install?

It does not seem likely that CS6 was upgraded from version 10. You might want to check your purchase history in your Adobe account to see if there is some missing link in the chain of purchases you made.
You can always try contacting Adobe support thru chat to see if they can find information or otherwise assist you in this matter.

I can no longer transfer photos from my mac to my i pad via i cloud
Accordong to i photo on my mac the photos are in i cloud
There is plenty of storage available
Don't know if it is just a coincidence, but problem arose after installing a new wi fi printer

There are apps such as Simple Transfer which allow you to transfer photos to/from your iPad and your computer via your wifi network - they will copy into the Camera Roll album in the Photos app on your iPad

After installing mavericks my computer no longer boots. I had 10.6.8. I've been told I need to zero my hard drive. Is that the same as erasing? Is zeroing absolutely necessary? If u zero will I have any OS at all?

My MacBook is mid 2010 or 2011 and was running 10.6.8. After installing mavericks my computer tries to boot, says it has to restart and that circle goes on and on. Disk utilities says everything is running okay and reinstalling mavericks twice didn't help. I was told my hard drive needs to be zeroed. How is that different from erasing and is it necessary as opposed to erasing? After I back up on an external drive (I know I should have done that before hehe) and erase or zero, what will happen to my operating system? Will I have the ability to reinstall mavericks or do I need to out a copy of it on the external hard drive? I'm wondering this because I don't know if my computer will be running snow leopard or anything at all after I erase or zero since I'm not entirely sure what those terms entail. Thanks for any help!

Ooops.
I upgraded my 10.6.8 system to 10.7.5. ..No problem, but my practice is to connect an ESATA dock to my macpro. install to the drive in the doc, use migration assistant to migrate my data and apps.   use the os in the doc for 2 weeks, if no issue then I delete the OS partiton in my Internal System Drive, do a carbon copy clone to the internal drive.
I just did the similar to upgrade to mavericks.   I installed to a new hardrive in my docking station.   (black widow esata dock). I noticed 10.9.1 is slow stayed with 10.7.5 as my operating system. now and then I would boot 10.9.1 fire up the console utility and fix the issues that made it slow....
Now I am at the "burn in stage" mavericks is now running fast and stable.   I'll use all my apps and if it does not break with the applications I run I will eventaully cc my 10.7.5 OS drive to the docking station, file the drive away.. and take my 10.9.1 drive in the doc and cc it to my internal system drive.
I always wipe out a partion when installing a new OS. Zeroing out is a bit more thorough, you will know if your drive is junk... but it's overkill for me.
I figured repartion is ok.
I'm 2 weeks away from doing a carbon copy clone from my 10.9.1 os drive in my dock to my internal drive.
by the way.. I am running Mavericks on a 8 core macpro 2,1. I have a modified bootloader that has an arbitration layer EFI32 to/from EFI64 emulated.
pretty cool.
And from new system standards, the old macpro stacks up pretty well:
