Installation problem with Steinberg UR44 Applications V2.1.1

I’ve bought recently UR44, and now i want to install my new audio hardware. I’ve systematically an error when i execute the setup “Steinberg UR44 Applications V2.1.1”, wich is part of TOOLS for UR44 V2.1.1 for Windows.

The first error message is :
An error occured during the installation of assembly component
{844EFBA7-1C24-93B2-A01F-C8B3B9A1E18E}. HRESULT: 0x80073715

After this one, a second error message appear “error 1603”, and Microsoft indicate to see about “Windows installer” OR MSDN help center for more information.

I’ve discussed by chat with a technician from Microsoft, , who has taken control of my machine. And for us, after different tests, the problem is directly due to Yamaha/Steinberg software.

I use Windows 10 64 bits and the last firmware Update V2.1.1 for UR44. I use Cubase 8.15 too.

Thanks a lot for your help, and sorry for my poor English :slight_smile:
