Batch processor 'not found'

I’m completely new to Image J and would appreciate some help. I’ve recorded a macro and want to process a whole folder of images but when I select process–>batch–>macro, instead of the window I get the error message:
"Plugin or class not found: “ij.plugin.BatchProcesser”
(java.lang.ClassNotFoundException: ij.plugin.BatchProcesser)

Any suggestions as to how I can install this gratefully received!

Dear @RThomas,

welcome to the forum! :slight_smile:

Which version of ImageJ are you using (i.e., where did you get it and when did you download it)? This seems like an issue that might be solved by redownloading ImageJ2 or ImageJ1 and trying again.

Best,
Stefan
