Auto-SummaryIf Adobe Photoshop is giving you trouble during installation or after installation, follow these steps to resolve the issue:
1. If you encounter an error during setup, run an elevated command prompt as Administrator. For 32-bit Windows Vista users, navigate to C:\Windows\System32\ folder and for 64-bit users, use cd ..\SysWow64. Then, type regsvr32 jscript.dll and regsvr32 vbscript.dll, pressing Enter after each. If issues persist, reinstall the Adobe installer.
2. If Photoshop appears already installed, first locate hidden files and folders in Windows Explorer by following the provided steps. Then, use the uninstaller to remove Photoshop completely. After uninstalling, manually remove remaining folders and files from specified directories and registry entries. Backup any personal files before deletion.
3. Remove shared components used by multiple Adobe applications. Adobe advises against removing shared files if other Adobe apps are installed, as it may cause issues requiring reinstallation.
Following these steps should effectively resolve most Photoshop installation problems.
Is it literally telling you it's already installed, or is it just giving you an error during setup?
If error during setup: Run an elevated command prompt as Administrator. For Windows Vista 32-bit user, ensure that the command prompt is at C:\Windows\System32\ folder. For Windows Vista x64-bit, issue the following command to change to 64-bit folder in order to use the correct DLL files: cd ..\SysWow64
Type the following command and hit Enter: regsvr32 jscript.dll
and optionally (if problem persists),
regsvr32 vbscript.dll
Run the Adobe installer again.
If saying it's already installed: Before you begin
Some of these procedures require you to locate hidden files and hidden folders. Some procedures require you to locate files by their full file names, which include extensions (for example, example_filename.ini). By default, Windows Explorer doesn't show hidden files, hidden folders, or file name extensions that it recognizes.
To show hidden files, hidden folders, and all file name extensions in Windows Explorer:
1. In Windows Explorer, choose Tools > Folder Options.
2. Click the View tab in the Folder Options dialog box.
3. In Advanced Settings, select Show Hidden Files And Folders.
4. Deselect Hide Extensions For Known File Types.
5. Click OK.
Remove Photoshop using the uninstaller
The uninstaller is designed to remove everything installed by Photoshop. When you start Photoshop for the first time, or when you modify the preferences, new folders and files may be created. To ensure the complete removal of all additional folders and files, proceed to "Remove remaining folders and files for Photoshop" below after you use the uninstaller.
To use the uninstaller:
1. Choose Start > Settings > Control Panel > Add Or Remove Programs.
2. Do one of the following:
-- If you installed Photoshop from the Photoshop CD, select Adobe Photoshop CS2 and click Remove. Follow the on-screen instructions to remove Photoshop.
-- If you installed Photoshop from the Creative Suite CDs, select Adobe Creative Suite 2 and click Remove. Follow the on-screen instructions to remove the Photoshop component.
-- If you installed Photoshop from the Production Studio DVDs, select Adobe Production Studio and click Remove. Follow the on-screen instructions to remove the Photoshop component.
Note: When you run the uninstaller, you will be prompted to remove, keep, or transfer activation. If you plan to reinstall Photoshop on the same machine, you may want to keep your activation. However, after you complete the manual removal, you will most likely need to re-activate Photoshop. If you plan to install Photoshop on a different machine, you should transfer your activation.

Remove shared components
Adobe applications typically install a number of shared components that are often used by multiple Adobe applications. Information about removing these shared components can be found in the following knowledgebase documents:
328358 , "Manually remove Adobe Bridge (Windows)"
333451 , "Manually remove Adobe ExtendScript Toolkit (Windows)"
333450 , "Manually remove Adobe Help Center (Windows)"
