Adobe reader 8.0

down load the adobe program compatible with mac o.s

You can use a PDF readersuch as Foxit PDF Reader which allows you to select text which you can then copy and paste.

try the steps below:
1. Right-Click on the PDF file.
2. Select Properties
3. On the General tab,
3.1. Check the Opens with: if its set to Adobe Reader
If not, click the Change button and select Adobe Reader

If the same thing happens, Uninstall all Adobe Reader installed on your computer. It is an indication that the installation is corrupted that's why it is not being detected.

I suggest that you can try to use Foxit PDF Reader instead which for me I find very convenient in opening PDF files.

Please let me know if the following has been helpful.

Adobe Acrobat is a family of computer programs developed by Adobe Systems, designed to view, create, manipulate and manage files in Adobe's

Plug-in from Adobe. It reads documents in PDF format on any platform.


A program from Adobe that lets you capture a document and then view it in its original format and appearance


Adobe has changed the names of the products in the Acrobat family regularly, also splitting-up, joining, or discontinuing products. Between version 3 and 5, Standard and Professional versions were one product simply called Adobe Acrobat.
As of October 2009[update], the current main members of the Adobe Acrobat family are:
Adobe Reader 8/9 Icon

• Adobe Reader 9 (Windows, Mac and Unix)
• Adobe Acrobat 9 (Windows & Mac only; no Unix version)
  • Adobe Acrobat 9 Standard
  • Adobe Acrobat 9 Pro
  • Adobe Acrobat 9 Pro Extended (includes Adobe Presenter)

The latest version
Version 9.0 Adobe Acrobat 9.0 was released July 2008:[10][11]

• PDF version 1.7 (and prior) supported. There are Adobe extensions to PDF 1.7 for Acrobat 9.
• Product Family includes: Acrobat Standard 9 (Windows only), Acrobat Pro 9, Acrobat Pro Extended 9 (Windows only).
• Pro Extended Version includes Adobe Presenter and the features of Acrobat 3D.
• The ability to create Acroforms was restored to Acrobat Standard in this release (in versions 6 through 8, Acrobat Professional was required).
• Enable real-time collaboration of PDFs with synchronized document views and chat.
• Improved Web Capture for capturing entire web pages or just some parts into PDF.
• Integration with acrobat.com to enable storage and sharing of PDF files.
• Personalize a PDF Portfolio with customizable templates for navigation and branding.
• Compare and highlight the differences between two versions of a PDF document.
• Insert FLV (Flash) or H.264 video for direct playback in Adobe Acrobat and Adobe Reader.
• Convert a variety of video formats to FLV for playback in PDF.
• Create PDF maps by importing geospatial files that retain metadata and coordinates.
• OCR PDFs (Paper Capture) using ClearScan. Adobe ClearScan technology creates custom Type1-CID fonts to match the visual appearance of a scanned document after optical character recognition (OCR). ClearScan does not replace the fonts with your system fonts or substitute them by Type1-MM (as in Acrobat 8 and earlier versions), but uses these newly created custom fonts. The custom fonts are embedded in the PDF file (this is obviously mandatory). If the OCR does not recognize a word with enough confidence, then the image (bitmap) of the word is shown in the PDF and the text is put above but hidden (same as what is made in "Searchable Image" mode).
• Adobe Reader 9 drops support for Adobe Reader Extensions 5 and 6 which permit Adobe Reader client software to save changes to filled-in forms in PDFs. Adobe Reader Extensions 6.1 and newer are still supported. Legacy PDFs will still be viewable, however they will open with the warning "This document enables Reader capabilities that are no longer enabled in this Reader version."[12]
• On March 10, 2009, Adobe Reader 9.1 was released which addresses a number of customer workflow issues and a critical security vulnerability while providing more stability.[13]
• On May 12, 2009, Adobe Reader 9.1.1 was released which addresses two critical security vulnerabilities.[14]
• On June 9, 2009, update version 9.1.2 was released which addresses a number of critical security vulnerabilities.[15]
• On July 31, 2009, update version 9.1.3 was released which addresses a number of critical security vulnerabilities.[16]
• On October 14, 2009, Adobe Acrobat 9.2 was released (added support for Windows 7 x86/x64 and fixed many security issues).[17]
• On January 12, 2010, Adobe Reader 9.3 was released which addresses a number of critical security vulnerabilities.[18]
• On February 16, 2010, Adobe Acrobat 9.3.1 was released which addresses two critical security vulnerabilities.[19]
• On April 13, 2010, Adobe Acrobat 9.3.2 was released which addresses several critical security vulnerabilities.[20]

When you select Advanced > Enable Usage Rights in Adobe Reader the Enable Usage Rights in Adobe Reader dialog box shown in Figure opens




Click Save Now and your file is enabled with the four items described above. You need Acrobat Professional for all enabling features. These commands are not available to Acrobat Standard users (Acrobat Standard available for Windows only in Acrobat 8). When you select the Enable Usage Rights for Adobe Reader menu command and click Save Now all enabling features are added to the PDF.

pleas say thank's

It sounds like you may have more than one version of Adobe Reader and/or Adobe Acrobat installed on your computer (not recommended) and the system is probably confused about which one to use when opening a .pdf document.
Right-click any .pdf file located on your system, and then, click Open With and then click Choose Default Program.


In the window that opens, select the program that you want your system to use when you open a .pdf file (in your case it should be Adobe Reader 9.1). It *should* be listed under the Recommended Programs section but if it is not then you will need to use the Browse button in order to located Adobe Reader on your system. If the correct program is already selected, then I suggest you unselect it and then reselect it. Make sure the "Always use the selected program to open this kind of file" check-box is checked. Then hit the OK button.
As stated earlier, it is not recommended (and not supported) for you to have more than one version of Adobe Reader installed at a time. You should do the following if the above solution does not work for you:
In Windows, go to Start Button > Control Panel > Programs > Uninstall a program
Look through the list of your installed programs for Adobe Acrobat and/or Adobe Reader. Uninstall them both (if you have more than one installed) then download and run the Microsoft Installer Cleanup Utility to remove all traces of Acrobat Reader.
Now re-install your latest version of Acrobat Reader only.

Solution: Remove Adobe Reader 7.0 and reinstall it.
Remove Adobe Reader 7.0, reinstall it into the Program Files/Adobe/Acrobat 6.0 folder, then try again to create a PDF document with Acrobat Elements 6.0.
1. Remove Adobe Reader 7.0 using Add or Remove Programs, and then restart.
2. Install Adobe Reader 7.0: At the Destination Folder panel, click Change Destination Folder and select Program Files/Adobe/Acrobat 6.0. Click OK, then Next to continue the install.
Background information
Acrobat Elements 6.0 is designed to work with Acrobat Reader 6.0. In order for Adobe Reader 7.0 to work with Acrobat Elements 6.0, install both applications in the same directory. Install Acrobat Elements 6.0 first, so you can install Adobe Reader 7.0 and select Program Files/Adobe/Acrobat 6.0 folder as the destination folder.

Very simple fix. Now and then after an Adobe Acrobat update Office will disable Adobe Acrobat as it is an add on. All you need to do is re-enable Adobe Acrobat. In Office 2007 goto Word Options, Add-ons, and at the bottom of the page is Manage. Click on the down arrow and select Disabled Items and click on GO. Re-enable Acrobat and you should be fine. In Office 2003, goto Help and selects disabled macros and re-enabler Acrobat.
