Google Chrome has recently stopped supporting the original CluckOnce extension, we’ve used to launch QuoteFab from RanFab. To restore functionality please remove the old ClickOnce extension and install the new one from this link. Restart your browser after and everything should start working as it used to.

Update September 29 2014.

It seems that Google Chrome has removed all ClickOnce extensions from it store. The new release for RanFab will no longer use this extension and in the mean time please use FireFox or IE11 which still work fine with ClickOnce. If you still wish to use Chrome you can try and manually install the extension by downloading it from here, followed by unzipping it and dragging and dropping the inclosed CRX file on the extension window from Chrome.
