It's been a few years since i messed with IPB.  Renewed my license, got the latest package, uploaded it, but when i go to install it i get stuck at this error

 

 

The compatibility checker and everything said all was fine.

Does anyone have any ideas?

 

thanks

okay nevermind, it randomly started working.  thx

Congrats on the renewal and getting the latest and greatest version of 4.x! 

Remember that you can always reach out for professional support that's included in your active license.  

Usually that error would indicate you have not uploaded all of your files, or some files were corrupted during the upload. You should reupload the files from the main zip to ensure everything is present on your server.

(That file, specifically, would be applications/core/sources/Advertisement/Advertisement.php)
