Last modified on: 12 October 2023

Problem:

When starting Revit/TheModus the following error message appears: "Unable to merge content store".

Cause:

When installing the new version the Content folder is not installed correctly.

Solution:

Follow these steps to solve this issue:

Close Revit.
Open Windows Explorer.
Browse to the folder mentioned in the error message: C:\user\<user>\appdata\local\Temp\ xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxx [see error message]\Cadac Group\TheModus Revit Addin\20XX\
In this folder select the TheModus.Template.Contentstore.zip and choose Copy.
Copy this file to the folder: C:\User\<user>\Appdata\local\Cadac Group\TheModus Revit Addin\Content
In case the Content folder is not present you can create it manually.
extract the copied TheModus.Template.Contentstore.zip here, making sure there is only one folder 'Content' which contains the folder 'Store' and the file 'TheModus.MEP.Library.xml'.
Open Revit and TheModus
Open the Settings and change the temporary path to: C:\User\[user]\Appdata\local\Cadac Group\Temp

These actions should resolve the errormessage.
