Unable to run current installer for Windows

[StuartR]

All,

I had previously installed JamKazam and tried to set up a usable configuration (prior to latest update).

Originally (maybe 6-8 weeks ago?) I was able to install, create an account, etc. However, was not able to create a working configuration.

I have greatly increased the wired network speed to the PC I am using and have plugged in PreSonus 26 audio interface.

I am confident that I should be able to set up a working configuration now - However, now I can't install the new version of the program.

Initially - I get a message that Windows Defender has protected me (against running the msi package). Then, if I direct it to open anyway - it says "This installation package could not be opened. Contact the application vendor to verify that this is a valid Windows Installer package".

Is there a know issue with the current Windows Installer package? Or?

Any help would be greatly appreciated.

Kind Regards,
-Paul

No issues I'm aware of. Sounds like the MSI executable you download got corrupted. Have you tried downloading it again?

Many times. 

Time to let Windows reinstall itself from scratch. It's an option in the boot menu... You can select whether to keep your user data or not. I've done this... Works wonders; just a few clicks and it's done in less than half an hour.
