A PDF suggestion from the NEI Webmaster

January, 2005

We've recently downloaded and tried the new Adobe Acrobat 7.0 Reader and have found it to be much faster than previous versions. We also suggest that you consider downloading the 7.0 "basic" version, which comes without all the extra bells, whistles and pop-up features...

Infected PDF files require Adobe Acrobat/Reader update

January, 2005

The existence of a security flaw in PDF files requires the upgrading of Adobe Reader and Acrobat software. PDFs are usually considered safe to open, and this is apparently the first exception since November 2000, when a hole was found in Adobe's version 4 software.

To eliminate the risk, take one of the following three steps. (1) Rename Adobe's eBook.api file, if you don't use Adobe eBooks; (2) Install the Reader 6.0.2 upgrade; or (3) Upgrade Reader and Acrobat to version 7.0. We recommend upgrading to Reader 7, just released last month, which is reportedly much faster than Reader 6.

iDefense has posted a description of the problem and workarounds for it...

Check here for the Reader 6.0.2 upgrade or the free Reader 7.0...

How do I speed up the performance of the Adobe Reader 6?

Speed Loading of PDF Files

By Neil J. Rubenking - 10/19/04

Our readers frequently ask why Adobe Reader 6 is so slow to load when they open a PDF file. The main reason is that the Reader doesn't load alone—it comes with a crowd of plug-ins. If you watch the splash screen carefully you can see their names flip past. Most people need only a handful of these plug-ins. If you'd like to load PDF files faster, follow these simple instructions:

* Launch Windows Explorer
* Navigate to the Program Files folder, usually C:\Program Files
* Below this, navigate to Adobe\Acrobat 6.0\Reader
* In the right-hand pane, find the folder named plug_ins
* Right-click it and choose Rename, changing it to plug_ins_NOT
* Create a new folder named plug_ins
* From the plug_ins_NOT folder, copy just three files to the new plug_ins folder: EWH32.api, printme.api, and search.api

That's all you need do. The next time you load a PDF file, only those three plug-ins will come along, and you should notice a significant speed improvement. If you need to read encrypted PDFs or if for any other reason you want to undo this change, simply close Adobe Reader, delete the plug_ins folder and rename plug_ins_NOT back to plug_ins.

What to Do When PDF Files Do Not Open?

If the Adobe Acrobat viewer doesn't display PDF files inside your Web browser as expected, try Solution 1 or update to the latest version of the Acrobat viewer. Some PDF's use security features that may not run in older versions. If these solutions do not fix your problem, try applying one or more of the other solutions listed below.

Solution 1 - Disable "view in browser" feature

Try disabling the "View In Browser" or "Web Browser Integration" feature in your Adobe Acrobat viewer. Doing this will convert your Acrobat viewer to display PDF outside your browser in a separate window. In most cases this will fix your problem.

Shown below is how to disable "Web Browser Integration"

Adobe Acrobat Reader 4.0 ( plug in )
Adobe Acrobat Reader 5.0 ( plug in )
Adobe Acrobat 5.0 ( full program )
Adobe Acrobat 6.0 ( full program and reader )

Adobe Acrobat Reader (plug in) 4.0

Go to < File > < Preferences > < General >

Remove "Check Mark"

Press < Ok >

< Close window >

Go to browser and try again to view the PDF.

When selecting the PDF file this time, you should get a window similar to the one above (may look different depending on the platform you are running).

Select < Open it > and a "second window" should open and display the PDF.

Adobe Acrobat Reader (plug in) 5.0

Go to...
< Edit > < Preferences >

Remove "Check Mark"

Press < Ok >

< Close window >

Go to browser and try again to view the PDF.

When selecting the PDF file this time, you should get a window similar to the one above (may look different depending on the platform you are running).

Select < Open it > and a " second window" should open and display the PDF.

Adobe Acrobat (full version) 5.0

Go to < Edit >< Preferences >< General >

Go to < Options >

Remove "Check Mark"

Press < Ok >

< Close window >

Go to browser and try again to view the PDF.

When selecting the PDF file this time, you should get a window similar to the one above (may look different depending on the platform you are running).

Select < Open it > and a " second window" should open and display the PDF.

Adobe Acrobat 6.0 ( full version and reader )

Go to < Edit > < Preferences >

Go to < Internet >

Remove "Check Mark"

Press < Ok >

< Close window >

Go to browser and try again to view the PDF.

When selecting the PDF file this time, you should get a window similar to the one above (may look different depending on the platform you are running).

Select < Open it > and a " second window" should open and display the PDF.

Solution 2 - Download PDF to hard drive

Make sure that the Acrobat viewer can read the PDF file by downloading it to your hard disk and then viewing it in the browser:

In Netscape Navigator 3.x or later:

Right-click (Windows) or hold down the mouse button (Mac OS) on the link to the PDF file, then choose Save Link As from the pop-up menu.

In the Save As dialog box, specify a name and location for the PDF file, and then click Save.

Choose one of the following options to open the PDF file:

In Navigator 3.x for Windows or Mac OS, choose File > Open File.

In Navigator 4.x for Windows, choose File > Open Page, and then click Choose File.

In Navigator 4.x for Mac OS, choose File > Open > Page in Navigator.

If you're using Navigator for Windows, choose either All Files or Acrobat files from the Files Of Type pop-up menu.

Select the PDF file you saved in step 2 and click Open. The Acrobat viewer should open the PDF file inside the browser window.

In Microsoft Internet Explorer 4.0 or later:

Right-click (Windows) or hold down the mouse button (Mac OS) on the link to the PDF file, and then choose Save Target As from the pop-up menu.

In the Save As dialog box, specify a name and location for the PDF file, and then click Save.

Choose File > Open and click Browse.

Choose All Files from the Files Of Type pop-up menu.

Select the PDF file you saved in step 2 and click Open. The Acrobat viewer should open the PDF file inside the browser window.

Note: If the viewer displays only a blank screen or returns an error after you've downloaded a PDF file to your hard disk, the viewer or the PDF file may be damaged. Exit the browser, restart the viewer, and try to open an Acrobat Online Guide from the viewer's Help menu. If the viewer can't display an online guide, the viewer itself may be damaged and you should contact Acrobat Technical Support. If the viewer correctly displays the online guide, try opening the PDF file you downloaded. If the viewer can display the downloaded PDF file, the PDF file isn't damaged; rather, your browser isn't working with the Acrobat plug-in. If the viewer still displays only a blank screen or returns an error, the PDF file is probably damaged.

Solution 3 - Check Security Options

If you use Internet Explorer 5.x, make sure that its security options recognize the Acrobat Control:

Note: This procedure changes Internet Explorer's security options for all ActiveX Controls. If you prefer to use stricter security, do not complete these steps.

In Internet Explorer for Windows:

Exit from Internet Explorer 5.x and your Acrobat viewer.

Start Internet Explorer 5.x.

Choose Tools > Internet Options and click the Security tab.

Choose the appropriate Web content zone for the type of PDF file you're trying to open (e.g. Internet or Local Intranet).

Click Custom Level to specify the security setting for this zone.

Select Enable for the options labeled "Download unsigned ActiveX controls" and "Initialize and script ActiveX Controls not marked as safe."

Click OK and then click OK again.

In Internet Explorer for Mac OS:

Choose Edit > Preferences.

Click Ratings and then click Options.

Select the option labeled "User Can See Sites That Have No Rating," and click OK. Contact Microsoft for more information on which security settings affect Internet Explorer's ability to download files.

Solution 4 - Are you looking at the correct window?

Make sure that you're looking at the browser window and not the Acrobat viewer window. The viewer runs in the background when you're viewing a PDF file in a browser window, and the viewer's window may not display the PDF file. If the browser window is inactive, activate it to view the PDF file.

Solution 5 - Large PDF's may cause problems

This item should not be a problem for any PDF on this SLAANEI site, since we don't have any PDF file larger than 4 MB. But for information purposes, some very large PDF files could force your Web browser to time out before it finishes downloading the file. If you find this a problem with other sites, ask the provider of the file to optimize it in Acrobat Exchange. For more information on file optimization, refer to the Acrobat Online Guide.
