OK. So here are some questions that Adobe should answer.
The license agreement I presume applies to my software installation permits one copy at home or on a laptop. It appears to permit that second copy only for the licensed user, so that it has two different license setups. The one is a machine license and the second is a user license. Forget for the moment what this does for the user who needs more than one user profile or even a different user on more modern machines to serve as a workable backup or for other reasons. And forget for the moment if Adobe is now able to determine these uses. If Adobe were smart about this, they would disclose immediately what is being done to prevent installations, as should Symantec. Failure to do so involves actions inside one's computer that these companies should carefully consider before continuing this process.
For Adobe: PLEASE LET US KNOW WHAT IS HAPPENING IN CONNECTION WITH YOUR LICENSING SYSTEM, AND WHAT HAS CHANGED DURING THE PAST FEW WEEKS (OR MONTHS) AS APPROPRIATE. USERS HAVE A RIGHT TO KNOW.
Next, the Deactivate portion in the Help | Activation menu works at times and at other times does not.
For Adobe: PLEASE LET US KNOW WHY THIS IS HAPPENING.
Installation is prevented in part by some portion of the operating system whether working in XP compatability mode or with the program working as an administator.
For Adobe: PLEASE LET US KNOW WHAT IS NOT WORKING.
The major issue here is not automatic installation, it is the failure properly to instruct everyone on what is happening and why. There are undoubtedly other problems here since the printer is not functioning and other things are not working. Worse, Office 2007 is not working with Acrobat, one of the main (if not only) reason some of us have bought Acrobat.
For Adobe: PLEASE LET US KNOW WHETHER AND WHY YOUR SOFTWARE IS FAILING, AND WHAT ELSE CAN HAPPEN. IN PARTICULAR, PLEASE LET US KNOW IF WE CAN JUST BUY ANOTHER LICENSE AND THIS WILL BE CORRECTED. THIS DID NOT WORK WITH SYMANTEC, WITH WHOM I BOUGHT FIVE ADDITIONAL LICENSES AND THEY STILL DID NOT INSTALL. I BELIEVE, BUT AM NOT CERTAIN, THAT THEY OFFERED ME MONEY BACK ON ALL OF ONE TYPE OF THEIR SOFTWARE BUT NOT ON ANOTHER THAT I TRIED TO SEE IF IT WOULD WORK. ESSENTIALLY, ALL SOFTWARE FROM SYMANTEC FAILED TO WORK ON THIS BOX, REQUIRING ME TO STOP USING ALL OF IT. I HAD TRIED TO USE CS3, AND PLANNED TO BUY A FULL VERSION. NOW I AM ALMOST CERTAIN NOT TO DO SO BECAUSE OF THESE LICENSE FAILURES.
