AS 2.0 Detect Acrobat Reader

Hi,
Is there a code to detect if you installed Acrobat Reader?
Thanks

Just wondering if the Netgear software package was installed for this device? It might not show up because the driver is not installed.

Detecting Acrobat Reader

I'm detecting Acrobat Reader in Flex using ExternalInterface and Javascript. Is there a better ( more reliable) way? I'd think flash player would already know this info?

Nope I'm not using AIR, it's a browser app. I do it by including this JS in my HTML wrapper:
// initialize a variable to test for JavaScript 1.1.
// which is necessary for the window.location.replace method
var javascriptVersion1_1 = false;
// initialize global variables
var detectableWithVB = false;
var pluginFound = false;
function goURL(daURL) {
     // if the browser can do it, use replace to preserve back button
     if(javascriptVersion1_1) {
          window.location.replace(daURL);
     } else {
          window.location = daURL;
     return;
function redirectCheck(pluginFound, redirectURL, redirectIfFound) {
     // check for redirection
     if( redirectURL && ((pluginFound && redirectIfFound) ||
          (!pluginFound && !redirectIfFound)) ) {
          // go away
          goURL(redirectURL);
          return pluginFound;
     } else {
          // stay here and return result of plugin detection
          return pluginFound;
function canDetectPlugins() {
     if( detectableWithVB || (navigator.plugins && navigator.plugins.length > 0) ) {
          return true;
     } else {
          return false;
function detectPDF(redirectURL, redirectIfFound) {
     pluginFound = detectPlugin('Adobe','Acrobat');
     // if not found, try to detect with VisualBasic
     if(!pluginFound && detectableWithVB) {
          pluginFound = detectActiveXControl('PDF.PdfCtrl.5');
     // check for redirection

     document.writeln('End Function');
     document.writeln('</scr' + 'ipt>');
Then in my Flex app, I call this:
hasAcrobat = ExternalInterface.call('detectPDF');
It works well actually. When I posted the question, I thought it wasn't returning the correct value all the time, but then realized the user had Acrobat installed but it wasn't the browser plug-in it was a stand alone version. I belive this script can only detect the browser plug-in.

Acrobat Reader not detected

Hi
I have enrolled in the Microsoft IT academy, and was able to complete the work, when one day the check at the beginning no longer detected acrobat reader plugin. i updated and reinstalled acrobat reader, but it is still not picking up the plugin. how do i fix this?
thanks

Interesting, thank you. Just a mistake, I think, or a very old site. It stopped being called Acrobat Reader almost 10 years ago.
My advice is to test that Adobe Reader is able to show a PDF in your browser window (NOT in the Adobe Reader window). Here's a link to try: http://www.adobe.com/products/postscript/pdfs/PackingLightBrochure.pdf
What happens?

Possible Adobe Acrobat Reader Problems?

I recently tried to bring up up a website that requires Adobe Acrobat Reader and he site stated it could not detect Acrobat Reader on my computer. I went to the Adobe website, which listed reader 9.4 for OS X 10.4.11. Is Adobe Reader similar to Flash Player where Adobe is not Supporting Mac Power PC and you are not able to load the most recent Reader for your computer? After loading from the Adobe site, I tried to mount the web page again. This time I did not get the notification that it did not recognize Reader on my computer. But it produced a dark screen with an in-progress circle rotating in the middle of the screen. After 5 minutes the web page still had mounted and I started wondering what the cause might be. Is there a later version I can load that will support OS X 10.4.11?

Hi Darrell, you guessed it...

Nothing for PPC.
Might see if PDF plug-in helps...

Acrobat Reader installed detection via JavaScript

I am curious whether or not Adobe plans on using AcroPDF.PDF.1 as an indicator of the most current version of Adobe Reader (for activeXObjects in Internet Explorer). I know that this will work for detecting whether Reader 7 is installed but now that I think about it, when Reader 8 comes out, if a user already has Reader 7 installed, obviously AcroPDF.PDF.1 will be defined in their registry so eval("new ActiveXObject('AcroPDF.PDF.1')") will return true. Does anyone know, Adobe specifically, how the next version of Reader will be classified in the ActiveX list (or registry key). Will it be AcroPDF.PDF.2?
The reason why I am asking is because I need to detect whether or not our clients have the latest version of Acrobat Reader installed for printing documents from our site. I apologize in advance if the following code looks really messy. This is my first post and I just pasted my code directly into the textarea box. Here's what my detection code looks like and works fine for now (but when Reader 8 comes out....hmmmm):
if(window.ActiveXObject) { // Internet Explorer var tryReader7 = true; for (var iVer = 20; iVer >= 0; iVer--) { try { if(tryReader7) { /********************************************* Check to see if Reader 7 is installed first. TRUE: Break out of loop FALSE: Set flag to false so that this check isn't executed each pass through by the loop *********************************************/ tryReader7 = false; // We only want to check ONCE var Reader7Exists = eval("new ActiveXObject('AcroPDF.PDF.1'); "); if(Reader7Exists) { // User met Adobe Reader Version Requirements oReader.installed = "True"; oReader.version = max_ReaderVerReq +".0"; oReader.message = aMessageStatus[4]; //"Adobe® Reader® installed" oReader.needsUpdate = 0; break; } } var ReaderExists = eval("new ActiveXObject('PDF.PdfCtrl." +iVer+ "'); "); if(ReaderExists) { // User met Adobe Reader Existence Requirements oReader.installed = "True"; oReader.version = iVer + ".0"; oReader.message = aMessageStatus[4]; //"Adobe® Reader® installed" break; } } catch(e) { // (minimum|maximum) version not detected oReader.message = aMessageStatus[7]; //"You do not have the latest Adobe® Reader® installed or enabled. } }

I am trying with Reader 9.
I am not trying to print from the server. The printing will happen on the client computers that is why I am trying to print using javascript from an html page. My clients do have different versions of Reader from 6 to latest
Is there any way to achieve it with out installing anything else on the computers?
Thanks,

This.print(pp) with interactive type silent or automatic does not work after upgrade acrobat reader 9 to acrobat reader 11

After an upgrade of acrobat reader 9 to acrobat reader 11 the automatic printing of a pdf. The pdf is opened, but the print does not happen. With acrobat reader 9 it works. But with acrobat reader 11 the printing does not happen.
I discovered when you specify pp.constants.interactionLevel.full it works on acrobat reader 11. But when you specify pp.constants.interactionLevel.silent or pp.constants.interactionLevel.automatic it does not work on acrobat reader 11. But with the full option we have a dialog print box
we do not want.
In our jsp we load a pdf document and create a message handler to detect the print events of a pdf document that is in an <object> tag.
In the pdf document we add

From the JS API Reference of the print method:
Non-interactive printing can only be executed during batch, console, and menu
events.
Outside of batch, console, and menu events, the values of bUI and of interactive are ignored
and a print dialog box will always be presented.

SignatureValidate() method not working in acrobat reader 5

Hi All,
Will the method signatureValidate() work in acrobat reader 5. the same pdf validation which is working in acrobat reader versions >= 7 and not working in version 5. Kindly let me know if there are any alternative methods available to detect the digital signature field changes in lower versions. Urgent help required on this.
thanks in advance.

Did you ever figure this out? I am also having problems with the "No Hand" javascript which turns off the (not very helpful) page-forward hand icon (a hand symbol with a down arrow) which confuses our users when in fullscreen mode. We create interactive PDFs and everything worked fine up to Acrobat X/Reader X. Now in XI it doesn't allow the internal link icon (pointing finger) nor weblink icon (pointing finger with W) to appear. It just remains a plain o’ hand icon no matter what you mouse over even though there are links present.

How do I activate Acrobat Reader at start up?

How do I activate Acrobat Reader at start up?

shauniemac,
Gulliver & Allan are absolutely correct.
The Startup Chime is part of the power on self test, and resides in the ROM.
If a fault is detected during the test, you will not hear a normal startup chime.
It is not an audio file that can be changed to another sound.
The Startup Chime is also needed to run certain troubleshooting procedures, such as resetting the PRAM.
Here ae two more utilities that will allow you to manipulate the volume.
Psst & Startup Chime Stopper.
You can also depress the Mute key went starting up.

Annotations on Acrobat Reader iPad

On my iPad 2, in some PDF documents, I cannot start annotations at the exact location of my preference; for example, annotations start at the end of the line and this cannot be changed.
Normally, for most PDF documents, the start and end of an annotation can be moved by the user.
Here is what I suspect is happening: the starting and ending point of an Acrobat Reader annotation may be moved word by word. This means that the Reader code detects where words break. In some documents (PDF books mostly, I would be happy to provide an example of such a document should it be asked of me) word breaks are not detected correctly.
It would be great if you could address this issue in a future update.
Thank you very kindly for your time and kudos on your otherwise EXCELLENT *FREE* Acrobat Reader for the iPad!

Windows 7 check registry for acrobat reader install

How can I check registry to detect if Acrobat reader (any version) is installed. I need to check this for Windows 7 and Windows Server 2008.
For Windows XP I was able to do this by searching for key: HKLM\SOFTWARE\Adobe\Acrobat Reader\10.0\Installer OR HKLM\SOFTWARE\Adobe\Acrobat Reader\9.0\Installer
and looking for the value of Path key.
Please let me know. thanks

SInce this is the Acrobat forum and not the Reader forum, I have no idea. You might try the Reader forum for the Adobe Reader product. There has not been an Acrobat Reader since version 5, and then it was also a different product.

Acrobat Reader update/download fail

I have Acrobat Reader 2.0.0.0. When I attempt to open it, I am required to download updates. The final update is upgrading to version 2.3.0.0. The problem is when I attempt to do the download/update, an error is detected and the download fails. What should I do?

You mean Acrobat.com? This is an outdated software which has been replaced with online services at https://www.acrobat.com/

"there is a problem with adobe acrobat/reader. if it is running please exit and try again. (523.523)

We are getting the following error "there is a problem with adobe acrobat/reader. if it is running please exit and try again. (523.523)" and a gray screen appears (Image not viewable) with multiple users. We are using Adobe Reader XI (11.0.05) and (11.0.06). The current workaround is to log off the website and log back in. Once the user logs back in, the pdf will appear. However it occurs anywhere from 2-8 times in a day. Anyone else having this issue or know of another workaround? Any suggestion with how to fix? Please help!!

Hi Valerie,
Please let me know the version of Adobe Acrobat/Reader & operating system installed on your computer?
Also, try this:-
Launch Adobe Reader/Acrobat.
From the menu, choose Edit -> preferences -> General
Uncheck the option for "Enable Protected Mode at startup"
Restart the Adobe Reader and web browser.
Regards,

I have installed adobe flash player. I can not open the file. In plugins under tools it is not showing. It shows acrobat reader being there but not flash player. Any ideas?

Flasher Player should be listed as a plugin in tools for it to work?

Chrome - Adobe-Acrobat/Reader can not be used to view PDF files in a web browser.

I can't view PDF files via Chrome (it works on Internet Explorer but I prefer Chrome) - the error below has arisen recently on Chrome, though I can't see what has changed.
"Acrobat plug-in
The Adobe-Acrobat/Reader that is running can not be used to view PDF files in a web browser. Please exit Adobe Acrobat/Reader and exit your Web Browser and try again."
I have looked through Forum articles on similar errors and have tried the following(text copied from other Forum entries)

None has solved the problem. However it still works ok with IE. But I want to stick with Chrome because I find IE is so slow!
I am using Vista, with Adobe Acrobat standard 9.5.2 and Google Chrome version 23.0.1271.64 m which is marked on Chrome as 'up to date'
Does anyone know why I might be getting this error on Chrome but not IE?

I think I have discovered the answer to my own question!
I have disabled Adobe Reader plug-in, and can now see PDFs in Chrome.
(Steps: Chrome Menu, Settings option, Click Advanced Settings link, then Content Settings button, then select Disable Individual Plug-Ins, and a list of plug-ins is offered to enable or disable).
I then get a different result depending on whether or not Chrome PDF viewer is enabled - with it enabled I see the PDF document in Chrome, or with it disabled then the option is offered to download it, but either way I can get it it via Chrome without having to run Internet explorer in another browser window.

Does any one came accross the following message trying to view PDF's in web browser? "Adobe Acrobat/Reader that is running can not be used to view PDF documents in Web browser. Please exit the Acrobat?Reader application and try again". Thanks for your help! Barbara
