Cannot update acrobat 9.0 pro

[Guest]

I have acrobat 9.0 pro which could be updated to version 9.4.5. I reinstalled the windows 7 system recently and reinstalled the acrobat 9.0.0. When apply the first update package 9.1.1, I got an error 'the upgrade patch cannot be installed because the program to be upgraded may be missing .....'.  I re-downloaded all the packages from adobe.com, still the same error. What's wrong?

Hi ,

You might be experiencing this issue due to incompatibility of Acrobat 9 with Windows 7.

It was good with the same system before re-installation, windows 7 pro 64-bit. By searching the solution from the internet, somebody mentioned update 9.1.0, where can I download it?
