Hello,I am doing installation testing of a in-house application.After installation of application on Win7 and Win XP it is observed that the installtion size for both the OS is different !!
For Win7 it is 62 MB checked at path > Control Panel\All Control Panel Items\Programs and Features\
For Win XP its 71 MB Checked at path> Control Panel\Add or Remove Programs\

Count and size of the files inside bin folder is identical.
What else constitutes this installation ?

Why this size difference is there?

Thanks in advance.
