Not at a usable windows system atm,but it this should get you to it:
Start - run
%appdata%\roaming\kodi\userdata\Database

I had the same problem till a few minutes ago. Thanks to Peppe I found the addon27.db-file, I deleted it and now I can enter Kodi.
So Dman1973, find that file, delete it and it is solved

I have one laptop lenovo 310 and newly built i7 system both have Windows 10 and both have Kodi 17 installed, they both run fine on them

[Dman1973]

it works very well. what do you mean with "nothing works" it doesn't start? a log will be useful http://kodi.wiki/view/Log_file/Advanced.

every single time, i downloaded, installed, won't start up, even tried microsoft app version. won't launch. working symbol for a few secs then nothing....

Post a Debug log (wiki).

Note that if Kodi won't launch then you can enabled debug logging by creating an advancedsettings.xml to enable debug logging, see http://kodi.wiki/view/advancedsettings.xml#loglevel

I am having the same issue. I updated to Krypton last night and Kodi did not launch. I uninstalled, reset my computer and then re-installed. It still does not launch. I deleted the addon27 but still nothing. I have read the topics about debug log but everything I click on or open does not have any information in it. When I load %APPDATA%\Kodi\kodi.log it states that it cannot find this page. I am not computer illiterate but this is stumping me.

Post the content of kodi.log at http://pastebin.com and the link you get back to this tread.

the page i suggested in my post doesn't exist anymore check the one suggested from jjd-uk
have you looked in your task manager if kodi is on http://puu.sh/va5Mn/faabad406e.png in the end a Debug Log is what you need to understand your issue.

[Dman1973]

I can't find that file... I reinstalled and am looking through?...

To perhaps make it a bit clear for the inexperience putting this in a

Code:

<advancedsettings>
<loglevel hide="false">1</loglevel>
</advancedsettings>

in a advancesettings.xml will allow Kodi to generate a debug log, so even though nothing may appear to happen there a chance this will capture what's preventing Kodi from starting up.

Note - the advancedsettings.xml may have if to created in which case refer to wiki pages http://kodi.wiki/view/advancedsettings.xml and http://kodi.wiki/view/Userdata

[Dman1973]

won't start up. I reinstalled it again and I cannot find this addon27.db file people are talking about.... still will not even fire up... Windows 10

[peppe_sr]
