I also stumbled across this dell site from a different post It should allow you to redownload all OEM software including Adobe that was purchased on the pc. Unless anyone has figured anything else out. Since I have nothing left to lose, so I will be trying it. It's necessary to remove the residual activation information from the previous Acrobat installation." Gave me a little hope.

This residual activation information conflicts with the activation of the newly installed version.

I don't have cs4, but the last paragraph " If you previously installed Acrobat, then the serial number and activation information that was used during that installation is retained on your computer. They sent me this Error "Invalid serial number" | Acrobat 9 | CS4 I also have the same problem, I was told my support oem uses a different installer and can't help. I feel better knowing I'm not the only one stuck in a never ending support loop. When a retail version of Acrobat tries to read the volume-license AdobeConfig.xml file, Acrobat returns the error. The correct AdobeConfig.xml file is given the suffix. The AdobeConfig.xml file without the "aiwbf" suffix is written for a volume-license version. On some Dell computers, a duplicate AdobeConfig.xml file is created when Acrobat 8 Standard is installed. Rename the to AdobeConfig.xml by deleting the "aiwbf" suffix.

The following two files should appear in this folder: Please re-install Adobe Acrobat 8 Standard and enter a valid serial number when asked."Ĭheck the alm_config_files folder for a duplicate AdobeConfig.xml file.Ĭ:\Program Files\Adobe\Acrobat 8.0\Acrobat\alm_config_files

When you try to launch Adobe Acrobat 8 Standard on a Dell computer, the program returns the error message, "You have entered an invalid serial number. Here is the text from a very old document for Acrobat 8 KB if you want to try it but I don't know if it will workĮrror: "You have entered an invalid serial number." when you try to launch Acrobat 8 Standard on a Dell computer I wonder if this is related to the previous version issue with Acrobat 8 that displayed the same or similar error?
