Can't uninstall 5.0.1.6

I tried uninstalling the program, but it fails.  How do I get rid of it cleanly, so I can re-install the later one.  I had installed it in the default install folder (C:\Program Files\OpenDCL Studio), except that I put a "-5" in the folder name (C:\Program Files\OpenDCL Studio-5), so I could tell which one I've installed and which one I'm using.

But now, that I have .7, I would like to use it.  However, I'm not able to install .7, nor am I able to un-install .6.

Even the Windows Cleanup Utilitiy (register cleaner) did not get rid of it.

What to do?

What happens when you try to install Beta 7? What error messages do you receive?

Good news, I was able to install .7, which I will use for now on.

I still have .6, which someday I might want to uninstall.  However, would it be safe just to delete the .6 folder and files manually?  I looked in the add/remove programs and it only displays the one install (.7).  That's why I think just deleting them would be good enough.

Any suggestions?

Thanks,
Paul

Yes, if you have successfully installed a later version, it's safe to just delete the orphaned files manually.
