Adobe Acrobat XI standard keeps asking to Validate the license key
I have a windows 7 64bit Standalone computer, with no internet connection. I installed Adobe Acrobat XI Standard version, the installation keeps asking me for the activation key.
I initially entered the Acrobat key in my standalone computer, a key was generated from the computer, then I entered the key in a second computer that has internet access (with my Adobe ID account), adobe activation key generated a key and I entered in my standalone computer. It works for a few minutes and then again asks to validate a key. Even when I think that it won't ask again, I logged on as a different user and here we go again . . . it keeps asking and asking to validate.
I have generated about 4 to 5 keys already from my standalone computer and Adobe Acrobat (activation website) has generated keys for me to enter in my computer, no luck so far.
Any help is appreciated.
Thank you
