cannot install from offline package

after you have downloaded/unzipped the offline stuff to the Downloads folder, you have to run setup in the folder containing the Downloads folder.

If you are a new bee to Sikuli or coming from 1.0RC3, I recommend to directly go to 1.1.0:
http://sikulix.com

read carefully!

Sukuli-1.0.1-Offline-Setup-IDE-option1.zip package doesn't contains setup file. It contains only:
1.0.1-1.jar
1.0.1-9.jar
ReadMe-Sukuli-1.0.1-Offline-Setup-IDE-option1.txt files

When I tried to install version 1.1.0 I got this error message:

1.0.1: the setup is the same as with online setup

1.1.0: I cannot see any error.
look and read carefully:
1. http://sikulix.com/quickstart
2. the information on the nightly builds download page

I got this again:

Obviously you have problems accessing the download pages needed in your network (blocked somehow for programmatic download).

So follow the advices on the nightly build page after this:
So you only would need to manually download anything using the below links, if you have problems with setup's inline download.
In this case you have to download the needed files according to the below information and run setup (so called offline setup)
