Quickcam10.exe will break your Thunderbird 2 install or upgrade
105 comments Added on 04/19/07 by Kris

Thought I would be cool and upgrade to Thunderbird 2 this morning from verion 1.5. Thunderbird is my trusty email program that keeps me connected to the outside world . . . my window to the world from the Smith manpit.

As a user for the last three years I know better:

than to have thunderbird or firefox open during upgrade
not back up the address book
not backup my email

Did my duty, began the install and kaput, "Error . . . r\n\r\nmozMapi32.dll . . .". Shit! But not a big surprise given my Thunderbird upgrade experiences.

Did my searches for the dll and ended up in a couple of places that didn't help but this one did.

Solution:

stop Quickcam10.exe (yeah, bizarre)
run install again
rejoice that the email gods have smiled upon you

24	I had the exact same problem, except mine was just quickcam.exe. I'm running Vista Business x64, and was exasperated. I tried to install a new TB on top of the old one and this just broke the current install without fixing the issue. If it wasn't for this page, I would have been stuck.

25	My thunderbird was stuck during its update process. I coundn't figure out what was going on. But, finally, I found the answer on this page. Thanks!!!

26	Had same problem and fixed it with the web cam solution. Excellent. Anyone have a fix for Thunderbird forwarding of pictures. Attachments don't seem to forward correctly.

27	Yup, this helped me also. Thanks!!!!!

34	Posted by: Kris at: 9:25am 11/24/2007
35	This tip is useful. stupid logictech Quickcam 10.0 interfaces with thunderbird mozmapi32.dll. Go figure why quickcam needs to lock that dll. It must be a bug.

39	Worked straight away after a lot of previous frustration.Thanks. I have had more than a few problems since installing Logitech's Quickcam. Looks like a wrong choice (it also crashes Skype which was the reason for getting it in the first place!)

69	Just thought I'd add some input for those of you still bewildered: I closed anything Logitech (and several other programs), but was still met with the same conundrum. I read elsewhere that removing the mozmapi32.dll file from the the Thunderbird folder would work--and lo and behold! It did! Or at it has so far.

73	Thunderbird had downloaded an update without my knowledge, then asked me if I would like to install it now. I didn't think much of it, and just clicked yes. It was after this that it was just stuck in a continuous cycle of error codes and frustration. Lo-and-behold, Quickcam10.exe is the culprit. Typical Logitech, they make great products, but their software just leads to frustration. Thank you, Google. And thank you, Kris.
73	Posted by: Trevor M at: 1:29am 05/02/2008
74	Yes, great, thanks! One has wonder, "Why?" Damn Quickcam10!

75	Just sending more love your way ... I ran into the same problem just now when Thunderbird tried to autoupdate itself. Finally, after deleting Thunderbird and trying to do a clean reinstall, Windows kicked up the mozmapi error message, which led me here. You rule.
