>Sorry for redirecting on old thread - but I figured you would know the answer to this. Does re-running

regsvr32 myocx.ocx

multiple times harm anything? Does it just "replace" the old enty or create another one, causing potential conflicts?

It just replaces the already present entries. IOW, there's no problem.

>Also - can we leave the OCX in our app's directory or does it need to be down in the system?

RegSvr32 uses the system path to resolve the file. If your ocx is in an application folder, you would be best served by supplying a complete path.
