I'm saying this because I don't know how MSE updates, but if they use MSI files to do that, that might explain things. Don't know what I need to modify and where for that. Only then will the MSI install work and even then, it says I doesn't have the rights to create a shortcut on the desktop. I've had to add the SYSTEM group to a lot of maps and give them full control, but shouldn't the SYSTEM already be there?Īlso, I had to remove the 'read-only' attribute from the ProgramData and Users folders, add the SYSTEM group there too and give them full control.

The oldest answer(the long post) here did not work.īesides this problem, I'm having trouble using MSI installers too. Restarted computer a lot of times now, checked for Microsoft Updates in general, but nothing shows up.ĮDIT: I've opened a bounty for this, because I really don't know what to do anymore. Tried it at home, at work and friends places, but never works. I presume that an error log is created somewhere, or an event log, but I don't know where to find those. For the last couple of days, MSE doesn't fails to update, remaining stuck at version 1.75.119
