Beginning troubleshooting

The tasks in this section can help you resolve the most common installation problems. Before you perform any of these tasks, back up all personal files. Always restart the computer after a system error occurs to refresh its memory. Continuing to work without restarting the computer can compound the problem.

To check how much RAM is installed, choose Start > Control Panel, and double-click System. The amount of RAM is listed on the lower half of the General tab in the System Properties window.

To check available hard disk space, open Windows Explorer, and then select the disk on which you want to install Acrobat. The amount of available space appears at the bottom of the Explorer window. (If the amount doesn't appear at the bottom of the window, choose View > Status Bar, and make sure that Status Bar is selected.) Make sure that the disk on which Windows is installed has at least 10% of its space available, even if you install Acrobat on a different disk or partition.

To increase available hard disk space, search for and delete any *.tmp files on your computer. For instructions, see the documentation included with Windows.

2. Check the DVD and DVD-ROM drives.

Dust or dirt on a DVD can interfere with an installation and prevent the DVD-ROM drive from recognizing the DVD. Examine the Acrobat DVD for dirt, dust, or fingerprints. Gently wipe the bottom of the DVD from the center outward with a soft, lint-free cloth.

Verify that the DVD-ROM drive can read other DVDs. If it can't, then examine the DVD caddy or loading tray for dirt, and clean it with a lint-free cloth. If it still can't read other DVDs, then contact the DVD-ROM drive manufacturer or the computer manufacturer.

3. Log in as an Administrator, and then install Acrobat.

Log in to the local machine with the Administrator account and then install Acrobat.

4. Create a different user account and then install Acrobat.

A user account can be corrupt or have security settings that prevent the installer from working properly. Installing Acrobat under a new user account can circumvent these issues. For instructions on how to create a user account, see the documentation included with Windows.

5. Install Acrobat from the hard disk instead of the DVD.

Device driver conflicts can prevent Acrobat from installing directly from DVD. Installing Acrobat from setup files copied to your hard disk can avoid conflicts.

To install Acrobat from the hard disk:

  1. Insert the Acrobat DVD into the DVD-ROM drive.
  2. Copy the Acrobat folder from the Acrobat DVD to your desktop.
  3. Run the Acrobat installer from the Acrobat folder on your desktop, and then follow the on-screen instructions to complete installation.

6. Install Acrobat in a simplified mode.

Device drivers and software that load automatically with Windows (for example, screen savers, virus protection utilities) can conflict with the Acrobat installer. To prevent conflict, reinstall Acrobat while Windows is in a simplified mode. This mode which disables some nonstandard device drivers.

To install Acrobat in a Windows simplified mode, do the following:

  1. Insert the Acrobat DVD into the DVD-ROM drive.
  2. Copy the Acrobat folder on the Acrobat DVD to the desktop.
  3. Disable startup items and restart Windows in VGA mode:
    1. Choose Start > Run.
    2. Type msconfig in the Open text box, and then press Enter.
    3. Click the Startup tab, click Disable All, and then click OK.
    4. In the System Configuration dialog box, click Restart.
    5. Press F8 when you see the message "For Advanced Startup Options . . . "
    6. Select VGA Mode from the list of startup options.
    7. In the Desktop dialog box, click OK to start Windows.
  4. Start the Acrobat installer in the Acrobat folder, and then follow the onscreen instructions.

  5. To get Windows back to normal startup mode:
    1. Choose Start > Run.
    2. Type msconfig in the Open text box, and then press Enter.
    3. In the General tab, choose Normal Startup. Click OK and restart.

Intermediate troubleshooting

If the tasks in the previous section don't solve the problem, try the following intermediate troubleshooting tasks.

Before you complete each task in this section, complete the following steps:

Note: These steps free up hard disk space and remove any damaged files (permanent and temporary) that the installer needs to overwrite but can't. Normally, the installer removes temporary files after it completes an installation. If problems occur, causing temporary files to remain, the installer can return an error the next time you try to install Acrobat.

  1. Exit from all applications.
  2. Uninstall Acrobat.
  3. Search for and delete any .tmp files on your computer.
  4. Delete the following items, if present, from the Documents and Settings/[ user profile ]/Local Settings/Temp folder:
    • Folders:
      • _istmp[ x ].dir
    • Files:
      • _ins[ x ]._mp
      • _inst32i.ex_
      • _inz[ x ]._mp
      • _isdel.exe
      • _istmp[ x ].dir
      • _setup.dll
      • _setup.lib
      • _wutl[ x ].dll
      • ~ins[ x ].~mp



        where " [ x ] " is any number

7. Install Acrobat to a different hard disk.

Hard disk problems can prevent Acrobat from installing correctly. By installing Acrobat to a different hard disk, you can verify if the original hard disk is preventing installation.

8. Repair and defragment hard disks, and then install Acrobat.

Installation problems can occur if hard disks contain damaged sectors or fragmented files. Repair and defragment hard disks by using either the error-checking tool and the Disk Defragmenter utility included with Windows or a third-party disk utility, such as Symantec Norton Utilities. For instructions, see the documentation included with Windows or the utility.

Run such utilities on each hard disk or partition. After you repair and defragment hard disks, install Acrobat in a simplified mode. (For instructions, see task 6.)

Note: Make sure that the disk utility repairs any errors that it detects. If you defragment a disk that contains errors, you can lose data. If the utility detects errors that it cannot fix, contact the computer manufacturer for assistance.

9. Check the system for viruses.

System viruses can cause erratic behavior and prevent Acrobat from installing. Use current anti-virus software, such as McAfee VirusScan, to check your system for viruses. Make sure that you have the latest virus definitions for the anti-virus software you use. Although virus infections are rare, they can cause strange system behavior, including system errors. Running virus-detection software regularly prevents viruses from damaging software on your system. For instructions, see the documentation for the anti-virus software.

10. Custom install Acrobat components.

An individual component can cause Acrobat to install incorrectly. By installing the components separately, you can isolate the one that causes the problem.

To custom install Acrobat components:

  1. Start the Acrobat installer.
  2. Click Next in the Adobe Acrobat 9.0 Setup dialog box.
  3. Follow the onscreen instructions to read the introduction, select a language, and accept the license agreement.

  4. Enter your name, your organization (optional), and the serial number for your copy of the program, and then click Next.
  5. Click Next in the PDFMaker Installation And Integration Information dialog box.
  6. Select a Custom installation, and then click Next.
  7. Click Next in the Caching The Installer dialog box.
  8. Deselect all the components to install the core features of Acrobat, and then click Next.
  9. After the core features are installed, start the Acrobat installer, and select Modify. Then select a desired component.
  10. Click Update to begin the component installation, and then click Finish to complete the installation.
  11. Repeat steps 9-11 to install each remaining component.

Advanced troubleshooting

If the tasks in the previous section don't resolve the problem, then hardware could be conflicting with Acrobat.

11. Try to install Acrobat on a different computer.

Try to install Acrobat on a different computer to determine if the problem is unique to your computer. If the problem is unique to your computer, contact the computer manufacturer. If the problem occurs on multiple computers, it could be a faulty DVD. Contact Adobe Technical Support.

12. Visit the Adobe User to User Forums.

You can see if other Adobe customers have a similar problem by visiting the User to User Forums at www.adobeforums.com.

If you confirm that the problem happens on other computers, Adobe Technical Support may be able duplicate and research the problem. Otherwise, see the system- or hardware-related information in Related Records.
