and many more

here the complete log

When installation fails, the significant exceptions lie near the end of the file.
Here, the installation fails at drivers setup stage, while trying to install a DLL in Windows system32 directory (exception reports errors on C:\WINDOWS\system32\difxapi.dll (Access is denied)).
To success with the installation, you should either ensure that you have administration privileges (and more specifically write access to this particular file), or disable the drivers setup if you don’t need them.
As already reported somewhere else, we plan to improve the installer, making it clearly reporting what was successfully installed and what was not… In such a case, other installations are probably OK, but you get a global error message just because of the failed drivers installation…

ok thanks, will try without drivers.
Anyway my user is local administrator.
May the dll already in use?
The installation will fail at first error or tries to go ahead?

The DLL is typically used for drivers automated installation. May you get a previous copy of the DLL because of a previous installation of Sierra Wireless drivers… Could be interesting to look at the creation/modification dates of the file, and check if you can rename/move/delete it from the Windows explorer.
Unfortunately, this kind error is fatal (for the drivers installation) and installer runtime won’t retry.
