Haskell installation - Win 7_64.txt

#1 Download Haskell platform from https://www.haskell.org/platform/. Select 64 bit Windows version .exe
#2 Remove any previous Haskell installation - haskell home, cabal directory. Uninstall stack with uninstall-stack.exe inside C:\Users\User\AppData\Roaming\local\bin
#3 Run the installer. Don't select any PATH change autometically during installation. Not for stack also. Don't select auto creation of STACK_ROOT
#4 Create HASKELL_HOME, STACK_HOME and STACK_ROOT system variable with proper path. Add that to PATH manually.
HASKELL_HOME=C:\Haskell Platform\8.2.1
STACK_HOME=C:\Haskell Platform\stack
STACK_ROOT=C:\Haskell Platform\stack\sr
Path=C:\Windows\system32;C:\Windows;C:\Windows\System32\Wbem;C:\Windows\System32\WindowsPowerShell\v1.0\;%JAVA_HOME%\bin;%GIT_HOME%\cmd;%GIT_HOME%\bin;%M2_HOME%\bin;%GRADLE_HOME%\bin;%AMAZON_HOME%\AWSCLI\;%NPM_HOME%;%NODEJS_HOME%;%RUBY_HOME%\bin;C:\GNU\GnuPG\pub;C:\scala\bin;C:\sbt\bin;%HADOOP_HOME%\bin;%HADOOP_HOME%\sbin;%SPARK_HOME%\bin;%ATOM_HOME%\bin;%EMACS_HOME%\bin;%ASPELL_HOME%\bin;%R_HOME%\bin;%ANACONDA_HOME%;%ANACONDA_HOME%\Scripts;%HASKELL_HOME%\bin;%HASKELL_HOME%\lib\bin;%HASKELL_HOME%\lib\extralibs\bin;%HASKELL_HOME%\mingw\bin;%STACK_HOME%
#5 Initilize cabal
cabal user-config init
this will create folder and file config under C:\Users\User\AppData\Roaming\cabal
#6 Modify config
extra-prog-path: C:\Haskell Platform\8.2.1\msys\usr\bin

#7 Upgrade stack
stack upgrade
#8 Update information in config.yaml file in STACK_ROOT folder. If this file does not exist then it will be created when you will run stack project or stack setup.
