Hello MUNKEY990,
Just checked it, works perfect, please be sure the extension size you have downloaded is: 135KB.

Regards, AS Team.
Yes. Actually it's showing 136KB. I have the same issue with your ASNivo Slider. Extension manager sais they installed correctly.
Hello MUNKEY990,

PHP version 5.2.17
Hello MUNKEY990,
Thank you for the info.
We made some changes, please download the package one more time, unzip it before installation and use extension for Joomla 2.5. Please let us know if you will have any problems.

Regards, AS Team.
Yes, that worked. Thank you very much.

Is it possible to do the same thing for the AS Nivo Slider? I get the same error with it.
Hello MUNKEY990,
The issue fixed.
