Failed to update
Error opening file for writing:
reaper_host32.exe

c:\Program Files\REAPER (x64)\Plugins\reaper_host32.exe

Reaper not recognising 3rd party plugins

I uninstalled the program.

files that did could not delete:

C:\Program Files\REAPER (x64)\reaper.exe
C:\Program Files\REAPER (x64)\Uninstall.exe
C:\Program Files\REAPER (x64)\Plugins\reaper_host32.exe

I tried to reinstall, but recevied the same error.

I then installed Reaper in a new directory – C:\REAPER

This worked and all is good now.
