420009 - Installer cannot open mozmapi32.dll

Status: RESOLVED DUPLICATE of bug 404609

(Thunderbird :: Installer, defect)

Description

[Chris]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.12) Gecko/20080201 Firefox/2.0.0.12
Build Identifier: Thunderbird 2.0.0.12

My older version of Thunderbird attempted an automatic update yet could not update all files.  After multiple attempts, I uninstalled and began installing build 2.0.0.12 from scratch.  I received the following message:  "Error opening file for writing", that file being mozmapi32.dll.  To make matter worse, i am unable to delete the Thunderbird files already written to my hard drive by the faulty installation.  If I try, I get the message that mozmapi32.dll cannot be deleted.  If I attempt to reinstall on top of the remaining files, I once more get that this file cannot be opened for writing.  I have unchecked "read only" but this has not helped. Help!

Judging by the duplicates of the update bug (bug 340535) and of the various installer bugs, 90% chance that it's quickcam, the software for a logitech webcam, that has mozmapi32.dll locked, and shutting that down will let you install/update. If not, someone in any of the support channels in http://www.mozilla.org/support/thunderbird/forums should be able to help you track it down, or sneak around it by installing in a different directory.

I had this problem, and it was the web cam. Shutting the web cam down, solved the problem.
