Re: NVDA Crashes on launch, log:OSError: [WinError 193]

This is a weird one.
Go here and see if you can run nvdaHelperRemoteLoader.exe:

C:\Program Files (x86)\NVDA\lib64\2021.3.1

What error do you get when you try that? That line of code is pointing at that file, and my hope is that even though it's not running under NVDA, we'll get a more useful error out of it.

Windows 7 SP1
During installation NVDA works fine. I can even select the option to Continue Running without doing an installation and it will work perfectly.
However once the installation is complete I can hear the NDVA startup sound which is immediately followed by the exit sound.
I have tried installing the latest version and even uninstalled, rebooted and installed the previous with the same results.
NVDA fails to launch with the same characteristics after a reboot.
Never does it remain in the taskbar.
While running in the Continue mode I can fully navigate the menus and have tried resetting/factory defaults but no change.
Even tried different voice profiles.
I have AVG Business installed and added the NDVA installed path as an exemption.
When I took a look at the logs I see this in the last line. OSError: [WinError 193] %1 is not a valid Win32 application.
