I extracted it with Uniextract and it works, only problem is path for languages and icon sets, as you put it in Program Data instead in app root folder.
Advantages:
- More users as lot of the people don't want to install too many apps.
- Applicable from USB on any PC.
P.S. - Try to make it like PortableApps, as it will give you more popularity.
P.S. 1 - I don't understand why you didn't included all languages and icon sets (people prefer full packages), or at least to make "light" and "full" package?
