From 2016 onwards the CreativeworX assets will be installed differently.
Separated product folders will keep more system memory free and will improve performance. This however means that you need to separately activate CwX assets in scenarios and that your existing scenarios using CwX assets will be broken.. I understand that this is unfortunate but the more CwX products will be released the bigger the problem with using the current folder structure will become.
How do I install the new versions?
The new versions will have a different installer program. It will ask for your serial key during the install process and you need to make sure you have an active internet connection. If the key checks out the assets will be installed in the CreativeworX folder under assets. The Re 421 Pack files will go into the CreativeworX/CwX_RE421/ folder. Other packs will go into their respective folders (CwX_RE420, CwX_RE620, CwX_RE460 etc.).
What happens to the old assets?
The old version will not be deleted automatically! This means that you could run both old and new versions together. This might be handy at the start to help you changing your scenarios so that they will start using the new version. The process will be a bit tedious but in principle you could go into the scenario editor and place the new engine next to the old one. Then move the circular scenario assets (on top of the engine) to the new version, delete the old and re-attach the engine to the wagons/consist. This should keep your scenario working in most cases. After doing this procedure for all scenarios you wish to keep, you can delete the old version of the engine using the uninstaller located in your RailWorks folder. You might also use RW_Tools for altering your scenarios.
Below you see that both versions of the Re 421 pack are available after install of V 2.0. The new version is SBB re 421.
The uninstallers for your old versions are located in : ../Program Files (x86)\Steam\steamapps\common\RailWorks\. For the Re 421 it is the file: UninstalRE421.exe
When will all my engines be updated?
I am currently working on updates for all CwX assets. Next to the new folder structure I am also doing other improvements to the models. This means it could take some weeks before everything is updated, You will be notified about any updates by email. Also you can keep track of things by visiting this website or on Facebook (https://www.facebook.com/CreativeworXforTrainsimulator/).
