Did you set you additional library folder to a path inside program files???
Yes. I setted: C:\Program Files (x86)\Anywhere Software\Basic4android\AdditionalLibraries
Are you sure you removed it from the correct path?
Yes. Right now the folder is empty
Check if you do set your additional libs folder to this path (Tools-Configure Paths)
Done
Also check if there is not another copy of this file (check Internal libs folder too)
There is nothing into Libs folder
