Error 2503/2502 Prevents Installation
Hello,
Iv downloaded 2.49 calibre for my windows 10 machine 64 bit, i did download the 64 bit version of calibre. During installation i get two error pop ups, error 2503 and 2502 which prevents installation, it states that it is the installation is premature and it does not install. Any help would be appreciated |

Basically the "Windows trusted installer" is broken/corrupt. Search for "error 2503 and 2502", there seem to be a number of different 'fixes' - don't use any that want you to download anything. This video shows several possible solutions using standard Windows features ==>> Fix: Internal Error 2502 / 2503 (.MSI Files) - YouTube BR |
