How to extract .msi file

The .msi installer will temporarily extract the files into C:\Documents and Settings\<username>\Local Settings\Temp, but those files are removed once the installer exits.

Step:
1. Start command prompt (Run as Administrator)
2. Type   msiexec /a filepath to MSI file /qb TARGETDIR=filepath to target folder

      

              Example:

              msiexec /a c:\testfile.msi /qb TARGETDIR=c:\temp\test  

3. Done
4. Then you will see a directory is created in C:\temp\test and file will be extracted in this directory.
