[TYPO3-english] cooluri - Installtool Upgrade Wizard issue

[Oliver Westerheide]

Hi,

i can't finish the Upgrade Wizard after install/upgrade cooluri to newest Version 1.1.1

The Upgrade Wizards wants to modify tables and fields right after fresh installation of cooluri:

Update database schema: Modify tables and fields

Change the following fields in tables:

link_cache: url, tstamp, sticky
link_oldlinks: link_id, url, tstamp
Change the following keys in tables:

link_cache: url
link_oldlinks: url

After click on Perform Updates the message Update successful appears but is started again afterwards with no end.

i tested a new installation in a 6.2.13 instance and a upgrade from 10.0.39 in another 6.2.15 instance with same results. 
Does anyone have an idea how to solve this?

regards Oliver.
