I installed X3e PE in a new 4790k and my PSP plugs (9 or 10 just got L'Otary!) which are all both installed as 32 and 64 bit, via the PSP multi-installer. I then installed Platinum and couldn't get them to show up. 
    Nothing is working or showing even after adding the PSPaudioware folder.
I have uninstalled all and want to start over. Is there any issue with the multi-installer and Windows 8.1 and Platinum, that I should be aware of?
 
Thanks for any help!

I uninstalled everything PSP and tried the multi-installer again and an error stopped it. So, I downloaded a fresh one and everything is working now.

Good news, I could not replicate but only have a couple PSP plug-ins. Might want to edit the subject and add [Solved]

Thanks Steve. That was certainly simple enough.
