(a) Is it possible to install most if not all Windows designed program (Windows programs/applications/software compatible between Windows XP-Windows 7 both 32 & 64-bit versions) like executables file formats (for example: *.EXE and *.MSI files) into the newer version of Linux Ubuntu v. 11.04? Please explain. (Also the Windows compressed file formats like: *.zip and *.rar too? Please explain.)
(b) Do I need some third party program like an intermediary facilitating program or catalyst-like program in order to make this happen? If so what program? Where do I find it and how do I install it in Ubuntu?
(c) Any known compatibility issues by using the latest compatible Windows based programs in Ubuntu v.11.04?
