Today I found out how to connect Palo Excel to Palo Suite.
1. Install Palo Suite.
2. Install Palo Excel.
3. Add additional host to the palo.ini in "\Program Files\Jedox\Palo Suite\palo\data"
http xxx.xxx.xxx.xxx 7921
4. Add additional host to the httpd.conf in "\Program Files\Jedox\Palo Suite\httpd\conf"
5. Restart Palo services
6. In Palo Excel, click Modeller, add additional host.
At this moment it seems OK.
Now checking the Modeller function in "First Steps with Palo for Excel".
