Hello, I have been using XE5 for many years, it has outlasted 3 machines. For the last two times I've simply reinstalled successfully, but this 3rd time I've come up against the install limit error, the registration failed. Is there a way that I can reset the active instance count given the situation, I accept that that request may be met with some scepticism. I can't think of any way to objectively demonstrate that there are no other instances in existence.
