Error starting MongoDB in windows 7 [32-bit]

Question

I followed a blog(link) to install and configure MongoDB in my system[Windows 7 32 bit].

As per blogger said, I have download mongodb-win32-i386-2.6.5 and extract to D:/mongodb/ and followed the blog

Upto installation everything alright, but when I try to start service using following command,

 D:\mongodb\bin>net start MongoDB

I got error response as,

System error 2 has occurred.

The system cannot find the file specified.

How to solve this ?

Update 2(result of @disposer's suggestion):

Answer 1

Run Command window as administrator and run net delete MongoDB

For running mongo as a service use this:

C:\mongodb\bin\mongod --bind_ip  0.0.0.0 --logpath  "C:\Data\db\log.txt"  --logappend  --dbpath  "C:\Data\db"  --port 27017 --serviceName "MongoDB" --serviceDisplayName "MongoDB" --install

then run Command window as administrator and run net start MongoDB

Answer 2

Download from this link @ http://downloads.mongodb.org/win32/mongodb-win32-i386-v3.2-latest-signed.msi?_ga=1.10304565.1436936475.1490595203

After installation in E: drive, run mongod command with options @ E:\Program Files\MongoDB\Server\3.2\bin> mongod --storageEngine=mmapv1 --dbpath C:\data\db

Observe, two options are necessary to be installed without errors, specially for 32-bit, --storageEngine=mmapv1 and create a directory in OS drive(c:) only as --dbpath C:\data\db

Keep your server running at command prompt, install mongobooster from http://s3.mongobooster.com/download/3.5/mongobooster-3.5.3.exe for GUI to manage mongodb. and connect to local database..try samples @ https://www.youtube.com/playlist?list=PL6gx4Cwl9DGDQ5DrbIl20Zu9hx1IjeVhO
