Hello, I recently had a hard drive die, and on it was my calibre library.

Now, I was mad I lost all my books, but the main problem I have is, I had calibre installed on that hard drive, and now calibre refuses to uninstall. Any help? And I also cant install it cuase it errors saying I have no disk space on that drive (the dead one, no duh) and I cant change the install location also because it says there is no E drive. Any help would be appreciated. Thanks!
