I have on my system both Acrobat 8.0 and 7.0, and they're not playing nice. Not only does sm no longer show pdf's in browser tabs, it also crashes sometimes, after giving a message box saying "Can't load Adobe plugin" or something like that. Talkback: TB27126400M

nothing useful in the TB trace. Incident ID: 27126400 Stack Signature 0x006500ab b507a3a4 Product ID MozillaTrunk Build ID 2006102609 Trigger Time 2006-12-10 01:22:13.0 Platform Win32 Operating System Windows NT 5.1 build 2600 Module URL visited http://www.haokets.org User Comments Seamonkey dies when it has problems with the PDF plugin, saying "could not launch Acrobat" right before the crash Stack Trace 0x006500ab 0x5ea33400

Adding "Acrobat 8.0 & 7.0" to summary, for ease of search.

Will TechNote by Adobe pointed by Bug 336184 Comment #12 help you?

To Eyal Rozenberg(bug opener): Problem when both of Adobe Acrobat 7.0 and Adobe Acrobat 8.0 were installed? (Read the TechNote by Adobe, please.) Or crash problem even when combination of AcroRd32.exe/nppdf32.dll of single version is correctly used? If latter, crash problem when 7.0? Or 8.0?

Well, I can't help with this bug any longer since I no longer have both applications installed. This can be closed as WFM if you like.

Closing as WORKSFORME.
