Acrobat Javascript and older versions of Reader

Hi,
I have created a basic Acrobat Javascript for my PDFs which reside at the document level.
What i want to know is, how backwards compatible is Acrobat Javascript? Will it work in older versions of Adobe Reader?
I have not managed to find much on this so any info would be appreciated. I just need to make sure the script runs to all my users regardless of what version of reader they are using.
Is this possible?
Thanks.

In addition to George's statement, you might also check the JavaScript version a specific Acrobat version supports; there have been a few useful changes in Core JavaScript 1.7 and 1.8 (in the Array object), which may prevent your script running properly in Acrobat 7 (and older).
On the other hand, with the exception of "security" annoyances, old code (developed in Acrobat 4 or so) usually still works in Acrobat 10. This means, that you can program for a specific Acrobat version, and it should be fine with several newer versions as well. If not sure, check the documentation (mentioned by George) and try it out.

Acrobat 9 create pdfs that older versions of reader can open

I use Acrobat to create pdfs for my classes. This session, many of my students can not open the pdfs that I created with Acrobat 9. This is especially true of students with older Operating systems and older versions of reader. Is there a way that I can create pdfs in Acrobat 9 that these older readers can open?

You should be able to set the backward compatibility in the Adobe PDF printer. There is a setting for the version there.

PDF saveable in older versions of reader?

We are wanting to make our scholarship application available online and I know that in the past a fillable form could not be saved with just the reader program. I know the newer version permits that, but I was interested to know which versions of the reader do not offer users the feature of being able to save the fillable pdf for future use.

"Backward compatibility" (with older versions of Reader) and "Extended Features" (the ability to save a filled form and email it) are Save settings in Acrobat (Reader has nothing to do with it). Additionally, Acrobat's EULA specifically places a limit on the number of forms you can legally extract data from (500) if created with Acrobat Pro. If you expect more than the limit to be returned, you'll need to look into an Enterprise plan with LiveCycle for form creation or your organization may violate the EULA for Acrobat.

Hello, adobe reader on my smartphone automatically updated to DC. However, reader worked better on my smartphone, how could i get the older version, adobe reader, back? Thanks

Question is above.

Hey ferdinanda26896064,
You can download the older version of reader from: Adobe Acrobat Reader DC Install for all versions
You need to select the version from the drop-down list

1) The older version of Bonjour can not be removed. Contact your technical support group.
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. 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 Bonjour entries and click "Remove".
Quit out of CleanUp, restart the PC and try installing iTunes again. Does the install go through properly now?
(If you do find a clean download site for the correct version of CleanUp, please don't tell me where it is. Without wishing to sound paranoid (although I grant it does sound paranoid), there is a non-zero chance that posting links to download locations for the utility here at Discussions leads to that download location being shut down.)

When uninstalling an older version of reader, I get an error message about transform paths

I tried to uninstall version 8.1.2, and I get an error message to verify that the specified transform paths are valid. Some body please help. I could use the 90mb of space it's taking up.
My system is a laptop, vista 32 bit. No security update issues are involved. I am running version 10, and simply want some memory back.

Claudia, thanks for the link. It removed the old version in about 30 seconds Microsoft Fixit looks like a great repair tool. Thanx for the hook-up. Redbaron8.
                                                                                Think of your family and friends often.
Always keep an eye on your enemies,
and be sure you know the difference between them!

If you feel you need erasing 90 MB. I would suggest getting some additional storage medium (external HD, ...). In any case, you may want to try the following: Run this fix from Microsoft: http://support.microsoft.com/mats/Program_Install_and_Uninstall Uninstall Reader using Add/Remove Programs

Usage of Leopard, Tiger and olders versions

Hello,
For my study I'm searching for information of the usage of Leopard and older version of MAC OSX. Has anyone an idea?
I can't find anything usefull on google
Regards,

First that article was written a few years ago. The prices of external drives has dropped much since then.
The flaw in what the article purports is that when the internal drive crashes, usually everything is lost. Even a corrupt boot sector or partition table or even a bad install can turn the drive into a boat anchor. And backing it up would require a separate backup for each OS and each partition.
It might sound convenient, and it is, until the HD fails and then it's a disaster.
I have Tiger on an external drive which is very small and if I wish, I can take it with me. It also serves as storage for other data and for TM.
The general rule of not putting all your eggs in one basket certainly applies here.
What you plan will probably work, but it is not something I would ever recommend or do myself.
On my PCs, I used to partition my drive so I could run Windows and Linux. I had multiple partitions for the several parts of Linux that can exist in their own partitions. When harddrives became inexpensive I installed a second drive for Linux and unpartitioned my original drive for Windows only. It's not only simpler, it's much safer.
This is only my recommendation, and nothing else. Maybe we all have to do things like this once. Just be careful and remember you must be very careful not to ever crash any of the partitions.

So I updated the itunes and now it won't open it, it states a message "the itunes library.itl" cannot be open because it was created by a newer version of itunes, I have unistalled and re-installed newer and older version and still i get this message.

I updated and now i can't use the itunes. I have unistalled several times, installing newer and older versions but still i get this message. Is there anything i can do to fix this problem??

Try the following user tip with that one:

How do I find and older version of instagram for iOS 6.1.6

How do I find and older version of instagram for 4th generation touch iOS 6.1.6?

In iTunes on your computer, download the App you want a compatible version for using the same Apple Id that the iPod has for the App Store. For Paid Apps its best to consult with the App maker to make sure there is a compatible App. With the App Downloaded to iTunes on a computer you can go into The App Store App on your iPod, Tap on Purchased, and Look for the App there. Tap on it to begin the download. It will likely say its not compatible, but if there is a compatible version it will offer to download it.
Install the latest compatible version of an app on an earlier version of iOS or OS X - Apple Support

Hi Manoj,

I have installed a free download from an older version adobe reader and it will not uninstall?

Most programs unistall easily from the control panels add/remove programs icon application.
This older version i installed on my computer will not uninstall.
Any sggestions.
It tends to stall out or not uninstall at all.
There is not even an unistall choice available any more on the add/remove programs.

You can try using this tool to remove all traces of previous version(s) of Reader:
http://labs.adobe.com/downloads/acrobatcleaner.html
Then, you can download the offline Reader installer from
http://get.adobe.com/reader/enterprise/
After downloading, restart your computer and run the installer before doing anything else.

Can Acrobat Pro 9 create pdf forms that are readable by older versions of Reader?

I have just downloaded the Trial of Acrobat Pro 9, and my client now tells me they only have Acrobat 5, and can't open the pdf form I've made in 9. My form uses text fields and checkboxes, tooltips but no validation or calculation. Does anyone know if it is possible to save this form in a way that is backwards compatible with Acrobat 5?
Failing this, does anyone know what version of Pro I need in order to add fields and still allow v5 to open the files?
thanks!
- Thea

I did not read your original post carefully. As far as saving a form that is readable in AA5, AA5 should be able to read an AA9 form as long as you did not use any of the new fancy things in it. In the meantime, simply save the form using either Reduce File Size or PDF Optimize with the compatibility set to AA5 or AR5. That process will strip any special issues from the PDF I think. At least that is my assumption. I create PDFs that are AA5 compatible all the time by simply having the properties of the Adobe PDF printer set to AR5 compatibility. As far as the form feature, that is really just a matter of being sure you use features that are AA5 compatible as I have suggested and saving, possibly using one of the two options I have mentioned. In most cases, AR5 will be able to read it even if you do not save in that process, but do not get fancy in the structure.

Older version of Reader

I need to have 11.0.2 in order to read a file from Grants.gov. I have 11.0.3 and cannot find the older version on your web site to download. Please help. I must submit the grant very soon.

You may have Acrobat set as the default app for handling PDFs, and that's the cause.
In the Reader Preferences under General
Click Select Default PDF Handler
Select Reader from the drop down and click Apply. This will stop Acrobat 9 from opening PDFs unless you choose to open with it.

Can I buy and older version of Indesign

Hi
The latest version of Indesign is to expensive for me. Could I buy an older version somewhere?
Thanks for your response
Elisabeth

You can try Amazon or other third party retailers - but be sure to check they are a valid Adobe retailer as there are scam sites out there.
Also - if you're a student you can get the Student and Teacher Price which is a lot cheaper than the full version, however the EULA stipulates different uses for commercial and private use depending on your locale - check the EULA before purchasing if you intend to use it commercially.
InDesign Creative Cloud is also available - it's a pay per month or an annual subscription.
And you don't have to get the entire suite you can get just InDesign for a small fee for a month, or subscribe for a small fee for the year.

Only if it's on a computer you have access to, or in a backup of it.
