Error 1723. There is a problem with this Windows Installer package. A DLL required for this install to complete could not be run.I get this when trying to reinstall Java. I've searched for help on Google and all references indicate I need to reinstall the Windows Installer, but I cannot find any downloads to enable me to do this for the version shipped with the BETA.Any help would be very much appreciated.ThanksC

Can you install other applications that make use of Windows installer? If so, then your issue is probably with your Java download. Go here for an interactive installation: http://java.com/en/. Go here to download the full binaries for an offline installation: http://java.sun.com/javase/downloads/index.jsp. If you do have issues with installing other applications via the Windows installer, open up an elevated command prompt and type SFC /VERIFYNOW. Wait out the scan. When finished, do a SFC /? to see the available actions you can take. Is your Windows 7 a clean load or an upgrade?

Hi, If other applications also cannot be installed with this error code, please check if PRC service work properly. Thanks.

I have had the same problem when reinstalling/repairing Quicken 2007. any ideas?

I tried this and it did not work. any ideas? I can install other programs.

There is a problem with the MSI software and not in any other app. It is required that Win 7 RC should update it at the earliest.

Hi there, I had similiar problem. In my case problem was caused by deleting java binaries from "Program Files\Java" (instead of uninstalling it). I've fixed it by copying these files from another computer, then I was able to uninstall remaining Jva update from "Program and features"and finally I could install offline version of JRE. Artur

I went through and search the registry for java and jdk and deleted everything that looked like it shouldn't be there anymore. Took a long time and who knows if I broke other stuff, but at least was able to reinstall java.

Currently, I have a variation of this problem - only worse. I am using Windows7 Pro 64-bit. The PC crashed with IE8 open. I rebooted and now cannot access any web sites that are Java based. Our own web site, www.nyghtfalcon.com, loads to the point that a java script runs, then the page stops loading. At first I thought it was IE8 so I loaded the IE9 beta. No better. I thought it might be IE so I installed FireFox which I don't like and that also can't run any java based sites. I followed all the directions noted above. I even ran SFC - the /VERIFYNOW option didn't work. I ran a full scan and no items were reported. I ran the veryfile option and it told me it couldn't verify the java download. I manualled cleaned the registry again, deleted all the java files I could find (save for application specific java files - like those used by Adobe products) and I still get this error and java won't install. Other applications install properly. There are no reported RPC errors. This is one of six PCs that were XP Pro. All were updated/upgraded to W7Pro 64 in February of this year. This is the first problem we have encountered. This is a product PC.... We are getting desperate.

Thanks C Yesterday, I just updated my Java using Update Checker, and it appear to my uninstalled files that, there's no icon on my new Java, and I try to uninstall it, it always appear the error 1723, and I install the real Java in the Java.com and now I have two Java, but the another one has no icon, and now.. I have this Bloom apps, for uploading photos for my Facebook, and now.. I can't get through it, because.. it need a registry refers to nonexistent Java. what that mean??? need help!!!

I have the same problem. I think it is disgraceful that Microsoft do not fix this. Everything else works on my PC for installing updates etc. but I cannot find a solution to this one. I have been in IT software for over 20 years and reasonably PC savvy (but not a techie) and tried registry cleaner, deleting java directories wherever I could fins them. But still no success. And Microsofts own installer will not reinstall.. Surely some technical wizard out there can fix this??

Yeah im getting an error for when i try to uninstall the program JAVA Update 6 it says error 1721. There is a problem with this Windows Installer Package, etc. So i tried to re-download JAVA and i get this error " lib/ext/dnsn.jar: Old File not found. However, a file of the same name found. No update done since file contents do not match. Now, i recently have downloaded a JAVA.JDK for BLUEJ computer program writing software but im sure thats not anything to do with it so if anyone knows anything please help
