One machine is Windows XP, Other is Windows 2000.
The size of update built on XP machine is approx 63 MB, where as the size of same updater on Win2000 amchine is 75 MB.
I am using InstallShield X (10.0) with SP1.
I am unable to understand this difference of more than 10 MB
Or just tell me if I should expect this difference in size, on different OS.
