What exact version of Opera are you downloading (or installing) from which site? And what does the site say about system requirements? Is the Archos 605 listed as supported? Is the Samsung Ace listed as supported?
What is the exact error message?
ive used the opera browser with the archos 605 wifi and loved it. i want to use the opera browser with my samsung ace smartphone, but when i try to download, it says file not supported. both, the low memory version and high memory, and wont work. are there steps im missing in replacing my ie with opera? any help will be greatly apreciated. thanx
