Dear customer,We are very sorry about the content compatibility issues in iClone4 which might have caused some confusion recently.
When upgrading to iClone4, you do not have to re-install all your previously purchased contents. Instead, you can manually copy the contents from their iClone3 folders to the new iClone4 folders without having to reinstall them.
To copy your contents from iClone3 to iClone4, please follow the steps below:
1) For example: The previous iClone3 template was located at the following location.
X:\Program Files\Reallusion\iClone 3\Template\iClone Template. (where X represents the drive on which iClone3 had been installed).
2) Copy above iClone3 folder to following iClone4 folder:
X:\Program Files\Reallusion\iClone 4\Template\iClone Template. (where X represents the drive on which iClone4 had been installed).
Please note however that copying your contents using this method will cause digitally protected contents to show a “Trial” mark in the content manager and watermarks to be shown when applied to your projects. There might also be the case that your contents become “invalid data” due to compatibility issues between iClone3 and iClone4. For instructions on how to resolve these issues, please see the solutions below.
Case 1: Your contents show a “Trial” mark on the thumbnail in the content manager and/or watermarks in the project.
This is the default case when manually copying contents from their iClone3 folders to the new iClone4 folders (See Figure 1).

Figure 1
Cause & Solution:
Since these digitally protected contents were not installed using their installers or downloaded from BackStage, they need to be re-verified for use in iClone4. Please make sure that you are connected to the internet when applying these contents in iClone4 for the first time. This only has to be done once for each content. If the “Trial” mark is not removed, please switch to another tab and return to the original tab to refresh the status.
Case 2: The thumbnail seems abnormal and the content cannot be applied into iClone4.
This is an exception where content developed in iClone3 cannot be properly read by iClone4. The program will note that it cannot load invalid data (See Figure 2).

Figure 2
Cause & Solution:
These contents have iClone3 specific settings which cannot be read by iClone4. We have re-packed the affected content packs for iClone4. You will need to re-download and re-install these contents using the newest installation files. Please follow the steps below to re-download your content pack:
1) Login to your member account:

2) Click on the “Order History” tab.
3) Browse through the list to find your content and its installation file download link.
Should you encounter any other content installation issues or have further questions, please feel free to contact the Reallusion support team: http://www.reallusion.com/CustomerSupport/User/QForm.aspx.
