"nodes should be the same"

The error message, "The process cannot access the file because it is being used by another process." says that the chainstate is being accessed by something else. This is Likely step 2. You need to close step 2 (press ctrl+c multiple times on it) after it is done building the genesis.

We rushed out the bat's to help users get going easier that were having trouble from the command line, so we may have named them a little confusingly, we will make the bats and process clearer and provide more documentation in the morning. To clarify the current bat process:

You only need to run Step 1 and 2 once, before the first time you run expanse. They are to setup and configure Expanse chain and your initial account. After Step 2 completes press ctrl+c to close the application.


Step 3. Runs Expanse, It should be run whenever you want to run expanse.
gpu_mininsolo.bat Starts mining. Expanse should already be running when you launch it.

So to clarify: Run Step 1 and 2 the first time you install expanse to get setup.

Then when you want to mine Run Step 3 if Expanse is not already running then gpu_mining_solo.bat ; If expanse is already running, you can just run gpu_mining_solo.bat. If you don't know if Expanse is running, try opening the Task manager and looking for 'gexp.exe'.

We will simplify and clarify this process further prior to launch.

Not right this second, ill compile one later.

Install Git from http://git-scm.com/downloads

Install Golang from https://storage.googleapis.com/golang/go1.4.2.windows-amd64.msi

Install winbuilds from http://win-builds.org/1.5.0/win-builds-1.5.0.exe to c:\winbuilds

Run win builds here. It's safe to remove big dependencies like QT and GTK which aren't needed. An exact list of dependencies should be determined

Setup environment paths

Add GOROOT pointed to c:\go and GOPATH to c:\godev (you are free to pick these paths).

Set PATH to %PATH%;%GOROOT%\bin;%GOPATH%\bin;c:\winbuilds\bin

Open a terminal and install godep first: go get -u github.com/tools/godep

Open a terminal and download go-expanse go get -d -u github.com/expanse-project/go-expanse

Try building expanse with go dep, navigate to c:\godev\src\github.com\expanse-project\go-expanse\cmd\gexp and run git checkout develop && godep go install

If you want to build from an other branch bypass godep go install for go install and checkout the dependencies manually.
