I think you want to have a portable Version of reefmaster ?!!
As Matt says this doesn't function.
But you can put all your workspaces on an external HD.
So you dont have to copy data from the NOT-Owned computer,
but still have to activate and deactivate
@Matt
was it possible for him to do this licence hopping as you described a lot of times,
whenever he wants to use different PCs,
but let the Installation on the not-owned PCs without the licence Key activated ?
And is there a chance for him,
to change the install DIR onto the external HD.
And then install on every PC he wants to use, RM on the external HD ?
Or are there any Registry Entries which belongs to the actual Version of RM, like 1.0.5...
which might conflict with my idea when updating on PC1, deactivating KEy, starting RM on PC2,
but from the same external HD and activate the Key ?
