MultiBit uses compressed private keys. Armory does not support that yet.

It's important to note that the new wallet format did not make it into upcoming 0.92. Hopefully it will be in the next release after that.

Armory does not import compressed keys.
You could use the "wallet details" tab of bitaddress.org to convert to a private key starting with a '5'.

Oh thanks i was writing while you reply.
I think i have written the same things you told me, Right?
Thanks for support.
Hum, reading the import "Info" there's written :
"All standard private key format are supported except for private keys created by Bitcoin-QT version 0.6.0 and Later"
If Multibit have the same way to create Private Key as BitcoinCore, this is the reason why Armory is not able to import my key
But if this is true, it's a very bad things
......Nobody using Bitcoin-QT have actually a previous version than 0.6.....

I have installed previous Armory Version (not Beta), But Same Error.
You could use this key as example :
L3VFfypeZNfkXgT2XDvUcwexkWDChxkcDnEhPcSAPwQRivUsSLHS
No way to import inside programs.
Thanks for your help

Ill get someone to look into it.
Hum well i could try but it was a fresh install (i have installed last version yesterday)
Haha I would suggest reinstalling Armory before anything. Save what you need and give it a good fresh install.
It's a "Demo" Private Key 
I'm not so N00B
I'm not so N00B
Just saying, I would delete that private key.
I have done another attempt :
Installed Multibit LAST Version 0.5.18
Private Key
L3VFfypeZNfkXgT2XDvUcwexkWDChxkcDnEhPcSAPwQRivUsSLHS
Public Key :
1ACM4eBKfkH2VZKTVBKdBbxdFunyJbJU8k
Now, on Armory (0.91.99.8 Beta)
- Double Click on current Wallet
- Import/Sweep Private Key
- Paste L3VFfypeZNfkXgT2XDvUcwexkWDChxkcDnEhPcSAPwQRivUsSLHS into the Private Key TextBox
- OK Button
- Same Error

I have copied only the private key (after the export from Multibit)
Ex : Labc123abc123abc123abc123abc123abc123abc123abc123abc
or Kdef456def456def456def456def456def456def456def456def
Ex : Labc123abc123abc123abc123abc123abc123abc123abc123abc
or Kdef456def456def456def456def456def456def456def456def
Did you copy in the time stamp as well?
Hi, i'm trying to import a Multibit Private Key (is a base58 key right?)
I have done an export from Multibit (follow this guide https://multibit.org/en/help/v0.5/help_exportingPrivateKeys.html)
And i get the private key in plain text format (it's a copy/paste from the guide) :
Now, with Armory (Current Last Version) i try to import the key and i get the following error :
"The private key you have entered is actually not valid for the elliptic curve used by Bitcoin (secp256k1). Almost any 64-character hex is a valid private key except for those greater than fffffffffffffffffffffffffffffffebaaedce6af48a03bbfd25e8cd0364141"
I copy this message from another user who seems to have the same problem : http://bitcoin.stackexchange.com/questions/24632/import-private-keys-from-multibit-into-armory
Multibit export Base58 Key right?
And Amory doesnt import Base58 Key?
thanks for help
