MongoDB wiredTiger Error: collection-*.wt does not appear to be a WiredTiger file (Window10)

Firstly instead of installing mongodb through apt just get a tar or zip of it.

1)Extract it to your home folder or wherever you would like.

2)Mark the mongod,mongo,mongos executable.

3)make a conf file say mongod.conf and add

 dbpath=conf/data/db
 logpath=conf/log/mongod.log
 logappend=true
 port = 27001
 fork = true

4)Start mongod by

 path/bin/mongod --config path/mongod.conf

"bin" because you will find mongod in bin folder after extract

I was not able to replicate, so here's my successful YAML config file (Windows 7 64 bit, MongoDB 2.6.1):

replication:
    replSetName: "rs1"
    oplogSizeMB: 512
storage:
    dbPath: "data"
    smallFiles: true
systemLog:
    destination: file
    path: "data/mongod.log"

How I started it:

C:\Users\Adam\mongo\2.6.1\bin>mongod.exe -f mongod-yaml.conf
2014-06-03T23:23:12.528+0100 log file "C:\Users\Adam\mongo\2.6.1\bin\data/mongod
.log" exists; moved to "C:\Users\Adam\mongo\2.6.1\bin\data/mongod.log.2014-06-03
T22-23-12".

And then (after an rs.initiate()):

rs1:PRIMARY> db.serverCmdLineOpts()
{
        "argv" : [
                "mongod.exe",
                "-f",
                "mongod-yaml.conf"
        ],
        "parsed" : {
                "config" : "mongod-yaml.conf",
                "replication" : {
                        "oplogSizeMB" : 512,
                        "replSetName" : "rs1"
                },
                "storage" : {
                        "dbPath" : "data",
                        "smallFiles" : true
                },
                "systemLog" : {
                        "destination" : "file",
                        "path" : "data/mongod.log"
                }
        },
        "ok" : 1
}

Note that I had issues when I used tabs to indent, which were resolved when using spaces. Case sensitivity was also a problem, but mainly due to muscle memory from the old config options.
