One of the methods:
1. back up both wallets from qt and armory (I hope you know how to do backup) (export private keys)
2. delete blockchain from %AppData% folder.
(1) Make sure Armory is closed. If you run Bitcoin-Qt/bitcoind yourself, close that as well.
(2) You need to find the Bitcoin-Qt/bitcoind home directory in your file browser. It can be found:
Windows: C:\Users\<username>\AppData\Roaming\Bitcoin
Linux: /home/<username>/.bitcoin
MacOSX: /Users/<username>/Library/Application Support/Bitcoin
(3) Within that directory, remove all files and folders EXCEPT wallet.dat. The only file remaining should be wallet.dat!
(4a) If you don’t run Bitcoin-Qt/bitcoin manually (or don’t know what I’m talking about), just start Armory. It will run bitcoind in the background, which will resynchronize with the network (4 to 48 hours depending on your connection).
(4b) If you run Bitcoin-Qt/bitcoind manually, restart it. Wait for it to finish synchronizing with the network (4-48 hours depending on your connection). A green checkmark will appear in the bottom-right corner when it’s done. Then start Armory.
3. BUT before you do point "4b" download NEWEST versions of both qt and armory

4. Import private keys after SYNCHRONIZING (point 4b)
ok, I did everything exactly as you said, right now just finished the whole process of BitcoinQt and continues exactly the same ..... I do not know what else can I do?
