Intermediate troubleshooting
If the tasks in the previous section don't solve the problem, try the following intermediate troubleshooting tasks.
Note: These steps free up hard disk space and remove any damaged files (permanent and temporary) that the installer
must overwrite but can't. Normally, the installer removes temporary files after it completes an installation. If problems
occur, temporary files are not removed. 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 the error-checking tool and the Disk Defragmenter utility included with Windows. You can also use a
third-party disk utility, such as Symantec Norton Utilities. Run these utilities on each hard disk or partition. For
instructions, see Windows Help or the documentation included with the utility.
After you repair and defragment hard disks, install Acrobat in simplified mode. (For instructions, see task 6 in
"Beginning troubleshooting.")
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 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. Click Next.
