				cant install calibre 3.0
			 
			
			
			I keep getting an error on version 2.61, I have 2.85 installed.  It says 2.61 cant be removed.  I tried downloaded both versions and couldn't do it.  If I uninstall caliber will I lose my library?  Or is there another solution.  Thank you

			No, nor will you lose your preferences. But to be certain, I suggest you take a backup, see ==>> How do I backup calibre 
		
	
		
		
		
		
		
		
		
		
		
		
	
	Make sure calibre is not running when you do the backup. BR  |

			If nothing works, you can do two things: 
		
	
		
		
		
		
		
		
		
		
		
		
	
	a) download the old installer. You will find it here: https://download.calibre-ebook.com/ and install it again. If this isn't working for you too, you can do it on the hard way. b) Delete the program directory (see https://manual.calibre-ebook.com/faq...is-not-working). This will not delete the library or your calibre settings. Both have different locations and calibre will find them with the new new installation.  |

 @Mystyee - and if its still not installing, repeat step b) above and then use a lightweight registry cleaner such as CCleaner. Whilst calibre itself doesn't put anything about itself in the registry the Trusted Installer, the Windows component that processes MSI installs, does. Then try installing latest version. Given the problem and what you've already done (reinstalling the 'stuck' version) I would do this anyway. BR  |

			Just download the 2.60 installer from https://download.calibre-ebook.com then tell windows where it is. That will let it proceed.
