Setup failed to run installation: The Remote Procedure Call Failed.

[Imatk]

As the title says.

I'm getting this error when trying to install the plugin for max.

"Setup fialed to run installation: The remote procedure call failed."

I'm running as an administrator.

I'm running Microsoft Windows 10 Enterprise
Version 10.0.19043 Build 19043

This is happening on every plugin I try to install for fume.

FumeFX 5, and also tried the beta FumeFX 6

Thanks for any help!
