OTF Error installing v5.20beta2 (FIXED)

[panicaftermath]

I get this error when installing the 32-bit v5.20beta2 on Windows 7.

This is for a portable install, overwriting an existing portable. When I click ignore, it continues as usual.

When I tried installing it again, same location, same error happens.

Font maybe used by another app? Try closing all opened apps.

[panicaftermath]

There are no other open apps.

And what other app would be using what appears to be a Reaper-specific (rea*.*) font file located in the plugin folder of a portable install?

[panicaftermath]

Odd. When I do a portable install to a new location, and even when I then reinstall to that same new location, I don't get the error. (Even after running the new install and using the notation editor, which is what I assume the font is for...?)

But it consistently gives that error when installing over my active R5 install folder. When I try to delete Reavura.otf from that folder, I get an error that the file is "open in System."

But what else would be using it if Reaper isn't running at the time?

Process Explorer might help.

[panicaftermath]

I looked using Process Hacker but it didn't show anything.

But when I rebooted, as expected, the file had been released and the install went without problem.

But it's odd how the system had been holding on to that one file.
