Many 64 bit programs don't work on Ubuntu 64 bit

[TritBit Software]

Many 64 bit programs don't work on Ubuntu 64 bit. Wine, skype, android sdk doesn't find executable, while 32 bit versions just work. Examples:
for wine
$ wine
bash: /usr/bin/wine: No such file or directory
$ whereis wine
wine: /usr/bin/wine /usr/share/wine /usr/share/man/man1/wine.1.gz
for Android sdk
$ ls
aapt aidl dx llvm-rs-cc llvm-rs-cc.txt source.properties
adb dexdump lib llvm-rs-cc-2 NOTICE.txt
$ ./adb
bash: ./adb: No such file or directory
for skype
$ skype
bash: /usr/bin/skype: No such file or directory
$ whereis skype
skype: /usr/bin/skype /usr/share/skype
I think many others programs have the same problem.
