This Viewer is No Longer Being Maintained
Linden Lab’s cashier update of 15 Jun 2016 is not supported. This means that you can no longer perform L$ transactions with this viewer.
This viewer is no longer being maintained. The most recent Windows release is based on Firestorm 4.6.9 which was released in Dec 2014; there have been many improvements and bug fixes in Firestorm and other viewers since then that are not included in CtrlAltStudio Viewer. Unless you really need Oculus Rift or stereoscopic 3D support you should use another viewer instead: either Linden Lab’s viewer or one of the other third party viewers such as Firestorm.
The CtrlAltStudio Viewer does not have a dedicated support team: it’s just me doing this.
If the problem you’re having is not for one of the CtrlAltStudio Viewer specific features (see the list here), please update to another viewer: the CtrlAltStudio Viewer codebase is out of date (see above) and no longer being maintained. If the problem is in regard to a CtrlAltStudio Viewer feature, you can contact me directly.
