Some users reported that my batch readerenable did not work, and they have installed Adobe Acrobat, after some checking, I got the answer, the installation of Adobe Acrobat has been changed, and need repair the installation of it.

The need to repair Adobe Acrobat can arise from a faulty installation or from file corruption that occurs at a later time. Adobe Acrobat 9 Pro provides a procedure to repair installation files without re-installing the program from the CD. If Adobe Acrobat is not running properly or you’re receiving a lot of error messages, the repair option will restore all installation files to their original state.

Instructions

1. Close all open programs. Frequently, installation programs need to access files that are also used by other programs. Closing all programs before you repair Adobe Acrobat will enable it to run without your input during the 10 to 20 minutes it takes to complete the repair. Moreover, you will be asked to reboot your computer at the end of the repair. If you reboot without closing all open programs, you may lose data.
2. Open Adobe Acrobat 9 Pro. Verify that no PDF documents are open. Although the repair should proceed without error, if you encounter problems it’s best not to risk corrupting an open file.
3. Begin repair. Click “Help,” and select “Repair Acrobat Installation.” This action will begin the repair process.
4. Reboot. Acrobat will notify you when the repair process is complete with a pop-up screen requesting that you reboot your computer. This can be done immediately or, if you have open programs and files that need to be closed first, it can be delayed. However, changes will not take effect until you reboot.
5. Verify installation. After rebooting, open Adobe Acrobat to verify that it is running correctly. Open a few PDF files and close them, perform some searches and so on. If prior errors occurred during specific operations, repeat those operations now. If you continue to encounter problems, check the “Troubleshoot Installation Errors” link in the Resources section below for a list of known problems and conflicts.from: http://www.ehow.com/how_6945861_repair-adobe-acrobat.html

It is a real case, and the author of Turn on Measure Tool in Reader for 25,000 PDF documents has been my customer, he bought my software Batch ReaderEnable, because he has already bought the license of Adobe Acrobat, so he just payed extra USD$39, and he can easily converted 25,000 PDF documents.
And, I’d like to correct something in his requirement,

I work for a city government and I have 25,000 scanned maps as PDF documents. Our users (they have Acrobat Reader(should be Adobe Reader) would like to be able to use the measure tool to measure distances on the maps.
From my research, it seems I need to turn on “Enable Usage Rights in Adobe Reader”(should be “Enable For Commenting and Analysis In Adobe Reader” aka “Reader Enable” and in Adobe Acrobat X Pro, it is called “Enable Commenting & Measuring…” ) in order for that tool to work in Adobe reader. Also from my research, it seems there is no way to automate, or batch process, these action for the 25,000 PDF files. There are some references on the web that LiveCycle can do this(Yes, Adobe LiveCycle can do it, but it is very expensive), but nothing confirmed, and when I called Adobe support they said in face, it was NOT possible to batch “enable usage rights“(“Enable Commenting & Measuring”). At. All. Period.
…

btw, Batch ReaderEnable Updates to Support Adobe Acrobat X Pro

My Batch ReaderEnable software supports batch convert PDF files with one of the following features,

• Enable For Commenting and Analysis In Adobe Reader(aka Reader Enable and called “Enable Commenting & Measuring…” in Adobe Acrobat X Pro)
• Enable TypeWriter Tool in Adobe Reader(aka TypeWriter Enable, called “Enable Adding Text in Document (that are not fillable forms)…” in Adobe Acrobat X Pro
• Enable usage rights for Adobe Reader (aka Usage Rights Enable called “Enable Additional Features…” in Adobe Acrobat X Pro)

btw, Batch ReaderEnable has three editions,

• GUI Version(Window Version)
• Console Version
• Hotfolder Automation/File Monitor/Folder monitor Version, automatically monitor the selected folder(with sub-folder) and convert the new PDF files in the folder
