Adobe Acrobat Reader in 64 bit Ubuntu

Some time ago I installed the official version 9.1 of Acrobat reader on my 64-bit Ubuntu desktop. If I remember correctly I had downloaded the distro-independent installer from Acrobat's website.

A few months ago an update to Firefox caused it to crash if Firefox were open at the same time. It took me a while to realize that was what caused it. At first I just realized that if I ever tried to open a PDF file from a web page it crashed, but other times it worked fine. Finally I realized the other times were any time that Firefox wasn't open.

A bit of Googling led me to a few threads about a known issue with Adobe 9 that caused this. Well, kudos to the Adobe guys because they listened, found and fixed the problem. Adobe 9.1.2 fixes the problem.

Since I'm running a 64 bit OS and Adobe only releases 32 bit Linux versions, I had to force the install of the Debian package by doing:

sudo dpkg -i --force-all AdbeRdr*

Now, no more crashes with PDF's. Yes, I know I could use eVince in Linux to natively display PDF files, but I've found a few display bugs with more complex PDF's and when Adobe is kind enough to produce a Linux version, I might as well use it.

I was using Acrobat Reader 9.1.1 on my Jaunty 64bit and had some issues with it (could not save a copy!).
Now with Version 9.1.2 this annoying bug is gone :)
I'm not sure if I had tried the new version without your report! Thanks for saving me some nerves ;)

That's why the blog - more

That's why the blog - more to save MY nerves than anyone elses though - you have no idea how often I refer back to this blog like a notebook to see how I did something in the past.

no joy

I was hoping these instructions would work for me on Debian64 (lenny), so I tried, it, and it DID install fine, but it can't find some blah blah, which IS on the machine, but apparently acroread is looking in the wrong place, and, of course, this being a closed-source, proprietary app, I can neither dig in there and tell it to look in the right place, or even find where it is looking and link or copy the lib to that location.
Adobe can suck my left one. Jerks.
They should just make a linux 64bit version.
