Windows Installer error 1721
Well, I know you don't really need to hear it, but you are probably better
off just saving data and rebuilding. I recomend the "FAST Wizard" to help with that. (If you have a net connection for storing data, this is especially good) Save settings and data with the Files and Settings Transfer Wizard (FAST wizard): Go To: http://www.aumha.org/win5/a/fast.htm -- Was this post helpful to you?

Windows Installer error 1721
I get this same error mesage when I try to install anything new after trying
to uninstall a program called "Mailshell Anti-spam Outlook Addin" I have gone intot he registry and deleted anything with the "Mailshell" word in it and have cleaned and compressed the registry. The Add/Delete programs doesn't see a trace of anything left and all the files are gone from the c:\Program Files directory. How can you remove the trigger that tells Windows Installer to look for such a file?

Windows Installer error 1721
I ran the Windows Installer CleanUp Utility and found nothing that looked
like the "mailshell" installer or files. Everything was just the normal windows update and jave stuff. It seems that there is a file, or list of files that contain items for the Windows Installer to use. I checked in the c:Windows\installer directory for anything that related tot he "mailshell" and found nothing. Where else should I look? "Mark L.

Windows Installer error 1721
It would do no harm to reinstall OE. I would try it to see if something in an
OE dependancy was changed by this mailshell. Search for msoe50.inf(The default location is C:\Windows\Inf folder) Right click the Msoe50.inf file, and click Install.

Windows Installer error 1721
I am still getting the error after reinstalling OE. As a side note, I tried
to uninstall the Java "JRE" and got the error. I tried to update my accounting software "Peachtree" and got the error. It doesn't seem to be tied to the Microsoft Outlook that I am using for a mail program, but to the Windows Installer. Any other thoughts? Is there a file or log that I can dump to look at to determine where the Windows Installer is getting the item to try and install? "Mark L. Ferguson" wrote: It would do no harm to reinstall OE.

Windows Installer error 1721
My guess would be that you are getting some Permissions error in the
registry. You might try a reinstall of the Installer, but that probably won't work either, if it's the registry. Running a downloader Installer install runs into the same issue. You might try Windows Defender. It's Software Explorer can look at a lot of those issues.

Windows Installer error 1721
Is there some way or program that will search the registry and find this
"mailshell" installer. I tried running regedit and searching for mailshell. I found a few items and deleted them with not fix for my installer issue. I have run ccleaner (www.ccleaner.com) which seemed to be a fairly good cleaner, but it did not detect this invalid installer. "Mark L.
