Monero Coin

What are the minimum requirements for a computer to run the Monero [XMR] wallet?
A 64-bit OS is highly recommended. At the time of writing (July 2014), 4 GB of RAM should be sufficient, and 2 GB of disk space is required to store the block chain (currently growing at about 6 MB per day).

How do I use Monero [XMR] with 32-bit Windows?
The official 32-bit binaries have been reported to work only with PAE enabled. More info here.
If you prefer to just move to a 64-bits Windows, here’s a tutorial.

Assume your 32-bit wallet file name is “wallet.bin” (adjust this instruction for other name accordingly)
Backup your wallet.bin.* files.
Delete ALL Monero files from your computer.
Download 64-bit Monero zip & blockchain.bin from 1st sticky page of this thread.
Unzip & place all the files downloaded above to the directory: “C:\Users\AppData\Roaming\bitmonero\”.
From the backup made at step 1, place wallet.bin.* files !!! EXCEPT wallet.bin itself !!! into directory at step 4.
Start bitmonerod.exe and wait for it to sync with the net.
Start simplewallet by the commad prompt: “simplewallet –wallet-file wallet.bin” (!!! name of the file that must NOT exist in directory at step 4 !!!).
When you want to stop any monero executables – ALWAYS type “exit” & be patient. Simplewallet re-creates correct version of wallet.bin for you.

Why is Monero not user friendly like most other cryptocurrencies? Why is there no official XMR GUI wallet?
Monero is not a Bitcoin clone, and so it’s code is entirely new (originally derived from Cryptonote). Similarly to the early Bitcoin days, a lot of pieces have just not been built yet – the puzzle is largely incomplete. There’s good and bad that comes with this fact, amongst other things: there is certainly some additional risk as the code is a lot more experimental than that of Bitcoin, while on the other hand, there is also a lot of potential, as Monero is just in it’s infancy. A GUI Wallet is certainly an important part of this puzzle, and there are unofficial GUI wallets that can be used (recognizing that they are test-quality software) – see the next question.

Here is what the core developers say about the native GUI wallet:

‘The GUI wallet won’t be just a CLI wallet with a GUI. I will also cater for payment processors and web wallets.’
‘We also plan to have a framework to do SPV-style clients like Electrum, so Windows users won’t have to sync the blockchain, etc.’
