Just a quick note, tried to install Indy (module 31), the URL has changed again. It's now up to build 5393. It would be nice if they had a "latest" so you didn't have to change it all the time.
I also tried to install JCL (module 98) and it failed to retrieve. The reason why this failed is unclear, since the ArchiveURL is correct. I can maually download the zip. I thought the way the archiveurl was being redirected by the server might have been the culprit, so I changed it in the ini to the redirected url. The process gets further - it downloads the archive, but fails to unzip it.
