Hi there. I also had issues updating TDM from 2.06 to 2.07, but on Windows 7. Thinking there might be an issue with my 2.06 install, I also tried use a previous copy of 2.00 which I had downloaded back in the days, and to update that instead: it updated up to 2.06 (seemingly without issue) and then failed to update to 2.07 when I ran the updater again, as it kept downloading and trying to apply the 2.05 to 2.06 patch again. Here are the logs : updating from 2.00 to 2.06 ; updating from 2.06… to 2.06 again ?_? By the way, I've downloaded tdm_update_2.06_to_2.07.zip using a browser from 2 of the available sources, and noticed that their CRC, according to 7-zip, was 44F83C6C, which does not match the one that's written in tdm_version_info.txt and in the first post. However: - both 7-zip and WinRAR confirm that there is no error when testing the archive - both 7-zip and WinRAR show something which seems a bit weird to me: there appears to be two different copies of scripts\tdm_custom_scripts.script within the same archive (see attachment).
