0x80070643 Error QR32 QWT installation

[0293784509247850924378509243578]

Hello,

for the Win7 QWT installation under QR32 I followed the instructions:

https://www.qubes-os.org/doc/windows-appvms/

I run this command (all is fine):

qvm-start lab-win7 --install-windows-tools

Than I started Win7, choose the D: drive and run the QWT exe file.

Here I got stuck with his error 0x80070643:

QWT 3.2.1.3

Error 0x80070643: Failed to install MSI package

How can I fix this, so my QWT is running well under QR32?

Kind Regards

Have you tried to disable driver signature checking policy as instructed in the README.txt file included in the cd-rom with the windows-tools installer?

[jidar]

Maybe a screenshot would help too, does the installer itself kick out
that message or something else?
