I had the same problem. (I have also posted this in the linked message above)
This happens only with the enpass-App installed from the Windows Store, not with the setup-File from your homepage (Enpass-setup.exe)
My Norton has moved the exe-file to quarantine; I tried to restore the file, but was unable to save it at original place. "Access denied"
I have used an usb-boot-stick with Linux to copy the file to it's path. It worked.
But after re-booting into windows - error message pops-up with same exe-File : "Wrong parameter"
At least I have uninstalled that windows-app from the store; installed the normal setup-file and all is working fine now
But I had to completely re-configure the program with my data.
