Database error while installing a plugin (think it has to do with mysql settings)

[Mithan]

I believe the problem I am having is related to my security settings with mysql NOT the mod I am trying to install, reason I am posting here. Maybe somebody knows what my problem may be.

I am using a new install of vB, so I doubt its vB itself causing the issue, but my server.

I am trying to install the following product:
https://vborg.vbsupport.ru/showthrea...=170592&page=4

However, I get the following error:

Database error in vBulletin 3.7.3:

Invalid SQL:
ALTER TABLE event ADD gwe_signup BOOL NOT NULL DEFAULT '0';

MySQL Error : Duplicate column name 'gwe_signup'
Error Number : 1060

Does anybody know if any settings could be causing that?

PS:
I have gone and deleted those tables manually and I have used the "over write" option when installing the product.

This still happens even on a clean install.
