I have all the installs for astrum installer. Astrum kind of closed down a couple years ago, but gave the registered users free usageand then made it a freeware program. I have the installer and all documentation arguably necessary to use it.
If interested, send a message to me. In most cases, all of it can be sent by email attachment.
I have not, but will zip all I have together that will include install and docs.

Even though win 10 was not out when astrum closed due to retirement, win10 is done just like win7. Nothing to change.

If I get tons of response, I will place the zip on the web and create a download URL.

It is still the cloosest thing to WISE installer(used by alpha) I have found without the expense.
