May 17, 2017 Adobe Employee. I want serial number for photoshop cs6. Correct answer by SheenaKaul. New Here, May 16, 2017.
Complete the following steps if you enter the serial number for your Creative Suite or stand-alone Adobe product and get the error message “This serial number is not valid for this product.'
Make sure you are using the correct installer for your product and platform.
Make sure that the number you enter is the serial number.
If your serial number is for a different language than the installation language you select (for example, you purchased a German Creative Suite, but attempt to install it in English), you will get an invalid serial number error. Reinstall the product, choose the correct language, and enter the serial number when prompted.
Note:
The following language-specific software installs two language packs. You can install in one language and enter the serial number from the other without getting an invalid serial number error.
Activation database files that are corrupted or have incorrect file permissions can prevent your product from installing correctly.
Delete the Adobe PCD folder and caps.db file from the following locations:
Windows:
Mac OS:
Restart your Adobe application. Enter the serial number when prompted.
If you are not prompted to enter a serial number or the application won't open, uninstall and reinstall the application.
Uninstall the application, if necessary. For Creative Suite applications, uninstall the entire Creative Suite, not just a single application.
Note:
If you are having problems with a stand-alone version of Lightroom, you must uninstall several files manually, after running the uninstaller. For instructions, see Uninstall Lightroom manually.
Reinstall the applications, using the Creative Suite installer and serial number.
The Creative Cloud Cleaner Tool can remove installation files for Creative Suite applications that are corrupted or that are causing problems with a new installation.
Note:
The Creative Cloud Cleaner Tool is designed to run after you uninstall your Adobe application. Run the appropriate uninstaller to remove the application producing the invalid serial number error first, and then run the Creative Cloud Cleaner Tool.
Uninstall the application. For Creative Suite apps, uninstall the entire Creative Suite, not just a single application.
Note:
If you are having problems with a stand-alone version of Lightroom, you must uninstall several files manually, after running the uninstaller. For instructions, see Uninstall Lightroom manually.
Download the CC Cleaner Tool.
Windows:AdobeCreativeCloudCleanerTool.exe
Mac OS:AdobeCreativeCloudCleanerTool.dmg
Caution:
Make sure to quit all Adobe Creative Cloud applications and terminate all CC processes before running the Creative Cloud Cleaner Tool.
Run the CC Cleaner Tool, following the onscreen instructions to remove the desired application.
For detailed instructions on how to run the CC Cleaner Tool, see Use the Creative Cloud Cleaner Tool to solve installation problems.
Note:
Check the system requirements before downloading and installing the product.
In the serial number dialog box, delete the serial number and select I Want To Try. Then click Next.
In the Software Setup dialog box, select I have a serial number and want to license this product.
Occasionally, a user account can become corrupted and prevent the Adobe installer from accessing or creating the necessary files and folders. Create a different account, log in to the new account, and then try to reinstall the Adobe application.
