Another possible cause that can induce this error message could be due to insufficient rights to certain folders of SCIA Engineer. This can be solved by giving full access for reading and writing in the following folders:
- C:\Program Files (x86)\SCIA (for SCIA Engineer 32-bit version) or C:\Program Files\SCIA (SCIA Engineer 64-bit version)
- C:\Users\<Your username>\ESAxx.x (for example ESA21.1 for SCIA Engineer 21.1)
Full rights can be given by selecting these folders and clicking on your right mouse button > Properties. Next you will need to give full control for your Windows username.
