Sorry to hear about the circumstance. Some background information can be found at the post http://www.advansyscorp.com/forums/topic/619103215/.
While the feature was introduced with good intention to help protect end-users from rogue scripts, due to the potential inconvenience of the default setting (which can be disabled with an installation config file setting), we have changed the feature’s default operation in the forthcoming GW7 compatible version of Formativ 2.0.
Unfortunately, post installation, the only easy way to reset the VBS settings on a central basis is to run a console utility which was written for this purpose. When run on the target workstation, it will restore the association and turn off the Formativ ‘disable associations’ Registry setting. The link to this utility will be sent to you via direct email.
