I encountered the error below when installing 11.0 C++/Fortran compiler for Mac OS. How to fix this error?
1) Architecture (IA-32 or Intel 64): Macbook Air (IA-32)
2) OS version: 10.5.6
3) Xcode version: Xcode 3.1.2
Root Cause :
The error "Invalid Serial Number" will appear if the user does not have write permission to the directory /Users/Shared/Library/Application\ Support/Intel/Licenses.
This directory 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® 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.
Please change the /Users/Shared/Library/Application Support folder privileges to 777. You will then install the product successfully.
