I have another software program that allows me to read in PDF files. This worked great in Adobe 9 but once I upgraded to Adobe Reader X 10.0.1 I can no longer see the PDF files when browsing the directory for them in the this other software. Other people using both applications are not having this problem.

What version of Reader are you using? Some newer .pdf files ure using formatting codes that older versions of Reader cannot decipher and thus fail to open. Older files will still read regardless of the version of reader. Ensure you have the most recent version of Reader and try again.

Check for any updates and optional updates in control panel.

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]

What error-message(s) do you get when you try?

If you're referring to the _free_ Acrobat Reader,
use Add/Remove Programs to uninstall it.
Then, download the latest version of the software from http://www.adobe.com -- most of the updates will already be integrated into the download.

If you're referring to the "full" software (that creates PDF files), find your original software, and license-key. Then, use Add/Remove Programs to uninstall it.
Restart your computer.
Reinstall from the media, using the license-key.
Then, do the "check for updates" within the software.

Don't panic,many people face this problem.You can use a third-party tool,such as advanced word to pdf 5.0,It is good in preserving the formatting.

when you send a job to your printer from the internet it is basically the same as downloading the program first before it can be spooled. this is causing a time out problem with your printer.
