eRROR 1723 wINDOWS INSTALLER PACKAGE dll NOT RUN

Error 1723 - There is a problem with this windows installer package. A DLL required for the install to complete could not be run.

This might be a privileges/permissions type of problem?

Try right-clicking on the actual Setup.exe and selecting the "Run As Administrator" option?  Do so even if your user is an Admin.

How to troubleshoot a problem by performing a clean boot in Windows Vista or in Windows 7

Have you tried cleaning out your Temp folder, you can do it by typing %temp% in the Start Menu RUN box.  This will open your Temp folder, there you can delete everything that Windows will allow you to do so.

It may be necessary to show Both Hidden and System Files, and also to uncheck "Hide known file types" in Control Panel/ Folder Options/ View, to navigate to the mentioned Temp location.

This example might or might not work for you with your program it uses the built-in Administrator account to perform the install?

"It seems that the "Run as administrator" command only gives you some administrative privileges, and they're not enough to install Java (and OpenOffice, by association). In order to get around this, you need to actually log into the built-in administrator. Open a command prompt with admin rights by clicking start, typing cmd into the search/run box, and hitting CTRL-SHIFT-ENTER. At the prompt, type:

net user administrator /active:yes

Then log out of your regular account and back in as the built-in administrator, where you might be able to install the program. When you're done, log back into your regular account and, for security purposes, disable the built-in administrator account using:

net user administrator /active:no "

Use the Vista instructions in this to reset to default the security settings.

How do I restore security settings to the default settings?
