Windows installation hangs

Hi

I'm running Windows 7 Enterprise, Service Pack 1 and I've installed Microsoft Visual Studio XE 2015.

I'm trying to install Intel Parallel Studio XE 2015 Update 2 Composer Edition for Fortran and C++

The installation ends prematurely with the following message:

Error message: An internal error occurred.

Error code: 1603

file name: w_cprosuite_common_p_15.0.2.179.msi

Any suggestions?

Thanks

Tim
