And got EXACTLY the same error as above.įinally, I switched to the SECOND laptop – one with a BRAND NEW copy of Windows. Uninstalled Lastpass, removed it from all the browsers, and tried to do the same installation. Here’s what I got – and what I get every time I attempt to put the desktop Lastpass on this system.

I then downloaded the installer and attempted to deselect a browser. I removed the extensions from ALL the browsers. The FIRST system I tried again, is a desktop running Windows 10 Pro that HAS Lastpass installed. And installed Lastpass using the Universal Windows installer that puts it in all the browsers and whatever, and if I understand correctly, ALSO installs the Windows desktop version.ĭoes ANYBODY have a sure-fire way to get Lastpass to INSTALL the desktop version? 'Cause one of the biggest reasons we dumped Dashlane was because the got RID OF their desktop version and force everything to go through a browser. ONE of the three computers has a BRAND NEW, shiny, unsullied version of Windows 10 Pro that I just installed. I always get exactly the same worthless error - 0x80073CF3. Then they tell me to install it from the Microsoft store. Talking to Lastpass has been utterly useless - they tell me to use the 'Universal Windows installer'. I have THREE Windows 10 PCs, two laptops and a desktop, and the Windows desktop Lastpass vault will NOT install on ANY OF THEM.

I DESPISE having to have a browser running every time I need ANY information from Lastpass.
