Just downloaded the 2.0.5 version of SIG pro. Unzipped it to produce 2 zip files. Have tried various ways to install the joomla 1.5 plugin. Tried the usual "upload package file" through Joomla, then uploaded the 1.5 zip file to a tmp directory and tried to install from there. Both result in:

unable to find install package

I've been hours at this. I've searched this forum. Found lots of questions, but no working answer. I have checked my cache dirs and they are all writable. Please don't tell me to check the requirements info. Been there, done that.

Any help would be much appreciated. Thank you!

This is what I followed to install the SIG PRO plugin. If it doesn't work maybe you're doing something wrong, or have an incomplete download:
