Right now I am running 13.0.4 32 bit on a 64 bit Windows 7.
I see that 13.0.5 was released, but when I click on “Check for Updates”, no new update is found.
This was also the case for the last versions, I suddely saw that I was running 13.0.0 although there was 13.0.4 out.
In Update Settings I configured to look every 5 days for updates.
UPDATE:
I deleted everything in C:\ProgramData\Emurasoft\EmEditor\updates and now it works.
