I was able to install ProjectLibre version 1.6.2 into my Laptop having Windows 10 OS last Aug 13, 2016. But started learning how to use it just now and I noticed that there is a new version 1.7 that is available and tried to update to the latest one. The installation however, was not successful and says that it encountered an unexpected error, It further says that this may indicate a problem with the package and two error codes was displayed; error code 2503 and 2502.
