Windows Client 8.0.5 Install failed

There ist a Problem with this Windows Installer package. A DLL required for this Install could not bei Run. Contact your Support personall or package vendor.

7.0.9 was installed on this PC before without Problems. Has anyone a glue what could cause this Problem?

Best Regards,


It sounds like you’re using something other than Windows 10. They have quietly removed the support for all other operating systems.

Even the still supported Windows 8.1/Server 2012 R2.

Hello @Andre ,

thanks for hour hint. But unfortunally i installed this Client on Windows 10. So this should not the problem :confused:

Has anyone else some ideas?

According to Jonathan Xu in the other post, they have not removed support for any OS.

@langhaarschneider Can you send the installation log file to support at
