Hi I am using OS 10.7.3 and Adobe Acrobat 9.5.0 Adobe Updater advises that there is an update to 9.5.1 (in this instance) and I start to download. The updater start to install the update and then comes up with an message: The Update could not be applied because the Adobe Acrobat application contents were modified since the original installation. Please reinstall Adobe Acrobat and check for updates again. Happens every time and I have not (knowingly) modified the application contents. I have even tried a manual installation of the update with the adobe support engineer on the phone. They have even tried via remote connect and failed - their solution. Yes you guessed it.

'The update could not be applied because the Adobe Acrobat application contents were modified since the original installation. Please reinstall Adobe Acrobat and check for updates again.' ​ I have not modified either of these since install (with the exception of installing their respective Adobe updates along the way) and was hoping that something has been discovered by now so that I don't go through the motions of reinstalling and updating both and then finding that they still won't update. Is everyone having this issue, or only some of us? And, is this incident isolated to Mac users only?

Does anyone know? It seems rather obvious that there may be something quirky about these particular updates since a few (or more) of us are having the same issue, without our having modified them as the install error message informs us.

I'm on an iMac 20' Intel (Desktop) DuoCore running a 10.6.8 Snow Leopard operating system. My original Adobe Acrobat Pro (v. 9.5.0) was originally installed along with the Adobe CS5 Design Premium package. I've had NO other issues until this latest set of 9.5.1 updates.

Any help out there? Thanks so much.

In addition, 'Reader' was renamed back to 'Acrobat Reader'. Following the introduction of Document Cloud, Acrobat.com were discontinued as their features were integrated into the desktop and mobile apps.
