I have exact same issue.  I own a copy of CS5.5 Master Collection.  I am trying to install just Acrobat X Pro on my new PC (64-bit with Windows 7 Professional) and I get an error message that says 'Invalid Serial Number' when I enter the Serial Number I have.

Use the chat option here to ask for you activations to be reset:

Wjat do yoi mean activation can be reset?


If you had this suite installed previously but never deactivated it, it could be a case where you need to have your activations reset, though nothing you have shown so far indicates that is the case.  Still, if you have no other installation on another machine then it cannot hurt to contact Adobe Support thru chat and ask them to reset your activations.  That way you are sure to have the two activations you are allowed available to you.

Where did you purchase it from?

When was it purchased?

What operating system?

What are your computer specs?

Have you installed it in the past?

I bought it from one German company who bought it from Adobe

I bought it before two or three years

Windows 64 bit

PC is strong enough

I tried to install it but not succeeded

Windows 7, 8, or 10?

If it is 10 that could explain the issue.  The software is too old for the system.
