6.0 standard invalid serial number

Question

Can someone help me out on this? I needed to reinstall 6.0 standard but now the serial number that I am entering is showing as invalid. Is there a solution short of buying new?

Hello,
I am sending a solution, try this it may resolve your issue,
Product type :- Acrobat 6,7,8,9.
Issue  :- Acrobat has technology in such a way that if you uninstall, reinstall it on the same windows computer or upgrade it to new version at the same windows computer, when you try to serialize this program during installation or after launch, it gives you error as "invalid serial no.",
Reason :- Reason is when you uninstall it or install the upgraded version which tries to uninstall the old version, at times it dosn't delete the registry keys from the registry editor at windows, so when you try to install the same version or upgraded version of Acrobat, Acrobat registry keys conflict with each other as they are almost at the same location.
Important Note :- Before you try this solution make sure you back-up the HKEYS on which you will be work, (To back-up right click on the HKEY, select option Export)
Solution :- 1) A) At Windows XP > go to start > go to run > in the run search bar type the command as "regedit", search for the same
                   B) At Windows Vista / 7 > go to start > go to search bar at the bottom of the startup menu > type "regedit", search for the same
                2) Regedit will open the registry editor > go to left hand side panel where you will see all the registry keys starting with HKEY
                3) Go to HKEY_CURRENT_USER, double click on that, same way go to Software/Adobe/Adobe Acrobat, Delete the key Adobe Acrobat.
                4) Same way go to HKEY_LOCAL_MACHINE/Software/Adobe/Adobe Acrobat, Delete the same
                    ( You may or may not see Adobe Acrobat key on both the HKEYS, if you see this key on only one HKEY, delete that, it may still work)
               5) Run the installation again.
