This machine has had Houdini run before-but now it can't.
-64 bit
-I can't install new licenses because lines Key2 and Key3 say License has already been installed.
-yet i cannot run houdini
-I tried to unistall all traces of houdini installs-but apparently this did not destroy the previous license information.

How do I clean this machine and re-install like a VIRGIN install?
I want to wipe out all traces of license servers and start again.

This sucks.
I feel like I can never run Houdini on this machine again!
With ever other 3d software I start fresh with an Unistall.
But Houdini sets a boobie-trap. Houdini and this machine are broken.
grrr!

Is there a bug with build 9.1.179?

look for a dir called “keys” in your WINDOWS folder

delete it


HTH

Indeed thats the issue-ya really have to know…

I hereby request a “remove old keys” button somewhere in
the Administrative Tools probably in License Administrator would do it.
