Try running the MS Installer Cleanup tool. Then you should be able to delete anything you need to.
Thank you for responding! I tried running that on a testbed/sandbox machine to test it out before using this fix on a live machine, and it resulted in me NOT being able to reinstall any Adobe Reader, any version, at all. When I tried to reinstall 8.1.x or 9.x, the download manager just reported that it was "unable to install" with not much else to go on.
It also left the Adobe Reader add-on installed in Firefox, and there was no way to uninstall it.
I'd love to try using the MS Installer Clean-up tool if I could understand exactly how I should proceed with it - exactly what steps I need to take.
Can you help me here? Again, I appreciate your response and look forward to getting this problem behind me!
"Try running the MS Installer Cleanup tool. Then you should be able to delete anything you need to."
I ran it on the Adobe Reader installation and I still couldn't delete those DLLs.
I've followed these uninstallation instructions to the letter. What's got these files locked?
I tried unregistering them that didn't work either - got "DLLUnregisterServer in AcroIEHelper.dll failed. Return code was 0x8007005"
Thank you for any suggestions.
The problem with the download manager, is not the same as unable to install. Try avoiding the download manager by downloading the full installer from the Adobe ftp site. Assuming you want Reader 9.2
I'm starting to get really confused as to what sequence of events I need to perform now.
I still have to uninstall Reader 8.x somehow, right? Do I follow the manual uninstall instructions at all now? Do I run the MS installer cleanup, and if so, is it lieu of the manual uninstall instructions, or in addition to, and if so, at what point? What about the undeletable 8.x DLLs?
Can you give me a summary of the sequence of steps that I need to follow in order to get rid of 8.x and get 9.2? It doesn't have to be very detailed - just a framework that I can follow and I'll take it from there.
Is there anyone else who can help me? I can't believe that this can be that difficult - I'm just overlooking something.
I don't know why these files are locked; it may have something to do with ownership.
Search Google for 'taking ownership', or also 'file unlocker'; this may help you to get the problem solved.
