Please can you elaborate on the issue?
If I understand correctly, you get an error when trying to install the root Open AT Embedded Software Suite package 2.34, but you can install all other packages separately?
Sounds like an already known issue where packages refuse to install if a corrupted package already exists on the disk.
Please have a look to the packages installation path (either the “dropins” subfolder of your DevStudio, or an external path like “C:\Program Files\Sierra Wireless\Embedded Software”).
You may have a directory looking like “com.wavecom.openat.softwaresuite.2.34.*”: if so, just delete it and retry to install.
There was no 2.34 package in the “Embedded Software” directory. I copied the “com.wavecom.openat.softwaresuite.2.34.0.201009161320_2.34.0.201009161320” folder from a friend and now it works…
