There's some confusion and strange rumors among beginners about how to install a Gamestudio update, like the latest to 6.40. Here are the most common questions answered.
Who is able to install an update? Everyone. We've made the update process as easy as possible - it requires maybe 4 mouse clicks to get your Gamestudio version up to date, and another 4 mouse clicks for updating the templates. You don't need to be an expert and normally don't need to edit any scripts. However you must be able to download and unzip files. If you can manage that, you won't have any problems with the update.
What the update can do: It updates your Gamestudio folder, the techdemo, and both the A5 and the A6 templates to the latest version.
What the update can not do: It can not modify your own game projects, does not update old A4/A5 games, and does not fix errors in your own scripts.
If you don't use the templates, and have written own scripts instead, you should be aware that using old A4 syntax is now indicated as an error. See "New Features" and "Old Syntax" in the manual about how replace old syntax by C-Script snytax. The same goes for the scripts of old A4/A5 Gamestudio games, like Adeptus, Triplane etc.
If you use the A5 templates, you won't have any problems unless you tampered with the template scripts or copied them elsewhere (which you should not do). In that case you need to manually overwrite your template copies with the updated template scripts.
If you use the A6 templates, the techdemo, or the Game Design Tutorial, you must also update your templates to 6.40. The 6.40 template link is next to the 6.40 update. Install it by unzipping the archive into your Gamestudio folder. It will update the techdemo and template scripts. Then, update the templates inside your own projects by applying the [Update] function under WED -> File -> Project Manager.
More information about the new templates can be found on the template forum.
