Installation issue on W2019 server - Keyset as registered is invalid

Hi there, 

M-Files Customer support has faced this issue earlier. 

As a first step, make sure that no antivirus software causes these issues. For example McAfee has been pointed to cause such issues on server machine in the past.

For that possibility, please review 

The "Keyset as registered is invalid" error message often indicates a corruption with some of your internal Windows files more than an issue with M-Files itself. Here is an article on Microsoft's answers forums describing a similar problem.

The course of action recommended in that article is as follows:
1) Set a Windows restore point that you can roll back to in case of system failure.
2) Open Windows Explorer and click on the View menu at the top of the screen. If Hidden Items isn't already enabled, enable it.
3) Go to your C:\ drive. Double-click on Users and then your user name. Double-click on Appdata, then Roaming, then Microsoft, then Crypto. Rename the "RSA" folder to "RSA Old".
4) Reboot the PC and attempt to re-install M-Files again.

Hi Timo,

thanks a lot for your answer, We tried your hints without success yet,

It seems that Antivirus topic could be the one, but we cannot easily change that.

Anyhow again thanks for your contribution.

Best regards,

Christian
