Failing to install due to old broken installation

The most relevant views. I'm trying to "re"install Calibre 64 bit 3.23 but it's failing because I was unable to uninstall my old version since one of my harddrives failed catastrophically overnight. I removed a key in my registry so that Calibre no longer shows up in the program list as you can see but somewhere the installer still knows about the old install and will not work since it can't uninstall this old version that doesn't exist. I can only get this far into the install because I changed the drive path of a USB to the old drive's path. I'm going to try installing CCleaner now to see if that can do something other than the registry work I already did. Thanks

I ran CCleaner, saw it delete some more things in the registry with Calibre in the drive path but the same problems persist.

In the interim you could install the 32bit version, it will use existing libraries and configuration settings, assuming you haven't lost them in the hard drive crash. The only downside is that very large conversions may fail due to insufficient memory.
