Adobe Acrobat 9.x co-existance issues with previous versions

Better think twice about integrating Adobe Acrobat 9.x into your environment.  From Adobe KB Technote 333223.

Although you can install Adobe Acrobat 9.x or Adobe Reader 9.x on a computer that contains an installation of previous Acrobat versions, it is not recommended. Acrobat 9.x Professional and Acrobat 9.x Standard use the Acrobat 9.x version of PDFMaker and Adobe PDF printer. When two or more versions of Acrobat are installed on the same computer, removing one version of Acrobat may disable functionality.

If two versions of Acrobat are installed on the same computer, only the Acrobat 8.0.x version of PDFMaker and Adobe PDF printer will be used, although conflicts may occurs if multiple version PDFMaker files are attempting to load.

When multiple versions of Acrobat exist on a machine, the running version will be used to display PDF files regardless of the preferences.

Removing previous versions of Acrobat or Adobe Reader after you install a more recent version can disable functionality. Repair the current version of Acrobat after removing the previous version. If the repair process does not restore all functionality, reinstall the current version.

Note: Adobe Technical Support does not recommend or support having multiple versions of Acrobat or Adobe Reader installed on the same machine (for example Acrobat 8, with Adobe Reader 9 or Acrobat 7 with Adobe Reader 8) . Acrobat and Adobe Reader have numerous components that have similar functionality and can cause conflicts on a machine. The most prevalent among these conflicts involves the plug-ins for rendering PDF files in the browser, PDFMaker inside of Office Applications, and the Adobe PDF printer. Using the Version Interoperability table below, remove all versions of Acrobat and Adobe Reader, and then install the current version.

  1. I am currently running 4 systems on a Microsoft Home network through a Netgear RP 614 Router and a Netgear WG602 WAP. Two systems are running under XP Pro SP2. One of these is a notebook connecting via 802.11b. The other is hardwired and running Adobe Acrobat V 8.1.2. The third is running under XP Media Center Edition SP2 The MCE is running Adobe Acrobat V5.0. The most recent addition is tunning under Vista Home Premium MCE with SP 1. I had originally installed Acrobat V8 on this unit and upgraded to Version 9 – which, during its installation indicated that V 8 would be uninstalled permanently on the system on which I was installing V9. It further encouraged me to re-install V8 on another system, if I so desired – thus the installation of V8 on the previously described system. The installation of V9 seemed to hang a little at the end, but finished with the “Installation successful” message and I clicked on finished. Ever since that installation, I have not been able to access, download and install updates to Acrobat Flash for Firefox V3 – neither can I access Adobe.com on this system using either Firefox V3 or IE V7 – although while flash videos will play using IE V7, they do not play using Firefox V3. To further complicate and confuse matters I am unable to access adobe.com on any of the systems on my network using either IE V6 or Firefox V2 – while flash videos do play on my other systems. Immediately I thought the problem was that somehow adobe.co m had been blocked by my router – a check with my router configuration and a call to Netgear support confirmed I had covered all of the bases. I then took my laptop to a another WIFI network and had no problem accessing Adobe.com. My next step was to do a “repair” on my Version 9 installation of Acrobat (remembering the hang at the end. This produced no improvement in ability to load the plug- ins for Firefox V3 or to access adobe.com. I then did a comparison check of the sysinfo for the reinstalled V8 and the repaired V9 relative to plug-ins. The list for V8 is at least 4X greater that that for V9. I then called adobe tech support, died on hold and contacted the HQ in San Jose and no one has yet to return my call – hence this note to you as your site came up in a Google search. Do you have any suggestions.

    Thanks in advance for your anticipated support,

  2. I resolved the problem at 1500 this afternoon. This was reading several posts on windowsbbs.com on an identical problem. After reading through 3 pages of threads, the individual with the problem arrived at the solution – UPGRADE THE ROUTER’S FIRMWARE & REINITIALIZE IT it worked like a charm. I upgraded Netgear RP614 firmware 614V1.11 to the latest and last available 614V1.14. I hope this helps anyone else who might be experiencing the same problem.
