Could not open the temporary zip file
 

I have a step of type "Enhanced zip files " failing with the message:
Could not open the temporary zip file
Any idea what is causing this?
VBP 8.0 ,source files are present,Temp folder is set empty but it always was ,problem started a couple of days ago,before it worked ok

If you don't specify a temp folder, the temporary directory is the destination ZIP file path. Check that there is enough disk space and that the user account the build runs under has appropriate file system rights to that folder.

thanks,it was a problem with folder rights indeed
