Got the following from a PC Help Forum.
When you start Adobe Photoshop, it returns the error "Unable to continue because of hardware or system error. Sorry, but this error is unrecoverable." When you try to save a file from Photoshop, it returns the error "Could not load alert resource!"
Do one or more of the following:
If you use Windows XP, run the Windows Program Compatibility Wizard to ensure that Photoshop isn't running in a compatibility mode:
1. Choose > Start > All Programs > Accessories > Program Compatibility Manager.
2. Click Next, and then select an option to locate Photoshop.
3. Select Adobe Photoshop, and click Next.
4. Select "Do not apply a compatibility mode," and click Next.
5. Uncheck any options for Select Display Settings for the Program, and click Next.
6. To test Photoshop with the new compatibility settings, click Next. Proceed as follows:
-- If Photoshop starts, exit it from it, return to the compatibility wizard, and select "Yes, set this program to always use these compatibility settings." Click Next, and follow the on-screen instructions to complete the wizard.
-- If Photoshop doesn't start, exit from the wizard, and see the other solutions in this document.
Defragment the hard disk where you installed Photoshop. To defragment the hard disk, use either the Disk Defragmenter utility included with Windows or a third-party disk utility, such as Symantec Norton Utilities.
If you installed Windows XP over a prior version of Windows, perform a clean reinstall of Windows XP, and then reinstall Photoshop:
1. Back up the files you want to save, for example, Photoshop files you created.
2. Uninstall Photoshop, and then uninstall Windows XP.
3. Perform a clean install of Windows XP: That is, select New Installation for Windows XP, not Quick Upgrade.
4. Reinstall Photoshop.
For more information, see "Windows XP Install Notes."
If you upgraded from Mac OS 9.0.4 to OS 9.1, remove and then reinstall Photoshop.
Note: Before you reinstall Photoshop, be sure to move any personal files from the Photoshop folder to another location.
Rename all AdobeFnt.lst files on each hard disk (for example, to AdobeFnt.old), and then start Photoshop.
Troubleshoot for damaged fonts:
1. Create a new folder (for example, C:/TrueType).
2. Choose Start > Settings > Control Panel, and double-click Fonts.
3. Move TrueType font files, excluding those installed by Windows, from the Fonts folder to the folder you created in step 1. (If you use a third-party font utility, such as FontMaster 6.0 included with CorelDRAW 6.0, remove the fonts using that utility. For instructions, refer to the documentation for the utility.)
Note: Don't move the TrueType fonts installed by Windows. For a list of the fonts installed by Windows, see "What TrueType fonts are installed by Windows?"
- Restart Windows and Photoshop, and try to re-create the error:
-- If the error recurs, one or more fonts installed by Windows may be damaged. To restore these fonts, reinstall Windows.
-- If the error doesn't recur, one or more of the fonts you moved are damaged. To identify the damaged fonts, move a few fonts back to the Fonts folder, restart Windows and Photoshop, and see if the error recurs. Repeat until you identify which fonts cause the error, and then reinstall them.
1. Drag the Fonts folder from the System Folder to the desktop.
2. Use the Extensions Manage control panel to disable all font utilities, such as Alsoft Master Juggler, Adobe Type Manager (ATM) Deluxe, Extensis Suitcase, or Adobe Type Reunion (ATR).
3. Restart the computer. The system creates a new System Folder: Fonts folder that contains the standard Mac OS fonts.
4. Restart Photoshop, and try to re-create the error:
-- If the error recurs, it isn't font related. You can reenable font utilities and move fonts back to the Fonts folder.
-- If the error doesn't recur, one or more of the fonts you disabled are damaged. To identify the damaged fonts, move a few fonts back to the Fonts folder, restart Mac OS and Photoshop, and see if the error recurs. Repeat until you identify which fonts cause the error, and then reinstall them.
Photoshop may not start or run as expected in a compatibility mode in Windows XP.
As you add, delete, and move files on a hard disk, its available space is no longer a single, contiguous block. If Photoshop is installed on a disk that has insufficient contiguous space, it may return an error when you try to start it or save files.
If you install Windows XP over a prior version of Windows, the upgrade installer doesn't update various Windows version-specific printer drivers, browser plug-ins, COM modules, configuration files, and registry entries. As a result, Photoshop may be unable to start and instead returns an error.
If you upgrade from Mac OS 9.0.4 to OS 9.1, you may need to reinstall Photoshop so that the Photoshop installer updates the new OS with the necessary Photoshop and system files.
When the Photoshop type engine starts, it reads information provided by the font manufacturer and then creates or updates the AdobeFnt.lst files. Multiple or damaged AdobeFnt.lst files may prevent Photoshop from starting.
Photoshop may also return an error if a font or the Fonts folder (Mac OS) is damaged.
