adobe reader not working on 64bit
I'm returning to Linux after several years, so I'm a semi-newbie with this OS.
I've had trouble installing Adobe Reader on Ubuntu 12.10. My PC is a 64-bit model and I tried the two command strings below. I don't understand the message I keep getting, because the .bin file should be in clear view. During my last attempt, I tried installing the Reader in the Desktop directory, with the following results:
roy@roy-EP45-UD3L:~/Desktop$ sudo apt-get install AdbeRdr9.5.4-1_i486linux_enu.bin
[sudo] password for roy:

roy@roy-EP45-UD3L:~/Desktop$ apt-get install AdbeRdr9.5.4-1_i486linux_enu.bin
E: Could not open lock file /var/lib/dpkg/lock - open (13: Permission denied)
E: Unable to lock the administration directory (/var/lib/dpkg/), are you root?
Any help would be appreciated!
Thanks in advance,
