ExcelApplication won't work

Hello,

Today I will try to use MSOfficeAutomation plugin . I Have create a new desktop project (Windows), but when I will play the project, it give me errors like:

Can’t find a type with this name
Dim Excel As New ExcelApplication

I have also read help and make this : … You will need to copy the MSOfficeAutomation plugin (located in the Extras folder of the installation) to the Plugins folder before you can use this class.

What I’m wrong:
Os: win8.1x64/ms office 2013/xojo desktop 2015r1

You did close & reopen the IDE after copying the plugin?

Yes

save project … close … reopen

QUIT the IDE
restart the IDE

thank you Norman i have kill xojo from tak manager and reopen, and now It works.
