MCL-1941Trying to install & play minecraft 1.7.2 or 1.7.4 ends with "Couldn't unpack natives!"
Have been playing minecraft almost daily since June 2012. Always worked fine.
On December, 5th, I got strange behaviour of minecraft which finally led me to (repetedly during the last few days) manually deleting all contents of the .minecraft folder as well as Java 64 bit through official Microsoft program delition mechanism.
After re-installing the latest Java 64 bit version I downloaded the MC launcher 1.3.6 but it always end with "Couldn't unpack natives!" in the Development Console". Tried multiple times.
Was hoping to have this solved in MC 1.7.4 but itdefinitley isn't. Also saw couple of similar reports from others yesterday but today I can't find them any longer?!

After three weeks research I gave up: The only way for my computer to get this fixed (MCL-1941) was to re-install Windows 7 Ulimate completely from scratch.
Some of the downloaded components were changed by whatever mechanism for whatever reason so that a "Hash did not match downloaded file" message as shown multiple times in the attached log of MCL-1941 appeared; finally leading to the famous "Could not unpack natives".
The explanation I found via google that might come closest to source of the actual problem behind that issue is that some program piece suspects some sound and/or picture files as malware and replaces them with some other arbitrary stuff leading to that "Hash did not match..." message. But although after deleting a couple of these "helpful" programms like "Avira ask search toolbar" the hash mismatch was gone; nevertheless minecraft crashed with some ogg file header issue...
