Problem : 

During installation, an error message of "Invalid Serial Number" will result if the user does not have write permission to the /tmp directory or the  /Users/Shared/Library/Application\ Support/Intel/Licenses.

Environment : 

Mac OS X, Intel Compiler 9.1, 10.1, 11.0
A related article pertaining to Mac OS X, Intel Compiler 11.1 can be found here.

Root Cause : 

The error "Invalid Serial Number" will appear if the user does not have write permission to the directories /Users/Shared/Library/Application\ Support/Intel/Licenses or /tmp.

These directories by default has write permission enabled, however, installation of other third party products such as Adobe products might change the permission for this directory. This change in permission will result in an error during installation of Intel(R) Compiler Products because the installer can not create a license file in this directory.

Even if the user provide their own license file instead of a serial number, the error will still occur if the installer can not copy the license to the directory /Users/Shared/Library/Application\ Support/Intel/Licenses.

Resolution : 

A more appropriate error message will be issue in version 11.1 of the Intel Compiler Products.  Assuming that you have a valid serial number or product license, the solution is to enable write permission for the directories Users/Shared/Library/Application\ Support/Intel/Licenses and /tmp.
