Copying File Failed - UnityEngine.Purchasing.dll

[siddharth3322]

I have transferred my project from Windows system to my iMac and try to export iOS build.
When there is a build process started on the spot, I was started getting this kind of error:

Also within Temp → StagingArea folder file is displaying in the locked state.

Now give me some suggestion into this so I can export iOS build for my project.

Try deleting your Temp and Library folders (make a back up first). Does it run OK in the Editor? Also, I trust that you Google’d first for this error and tried the suggestions? “Unity copying file failed” returns several suggestions.

Deleting Temp and Library folders solved my problem.
