ERROR: Architecture is not defined. Accepted values: ia32, intel64

Dear Experts,

I have recently downloaded and installed parallel_studio_xe_2018_update1_cluster_edition for a single user on my linux environment (Debian 9.1). The installation was successful however when i try to set variables in the command line with:

 $HOME/intel/bin/iccvars.sh intel64

I get the following error:

Syntax: source daalvars.sh <arch>
Where <arch> is one of:
  ia32      - setup environment for IA-32 architecture
  intel64   - setup environment for Intel(R) 64 architecture

If the arguments to the sourced script are ignored (consult docs for
your shell) the alternative way to specify target is environment
variables COMPILERVARS_ARCHITECTURE or DAALVARS_ARCHITECTURE to pass
<arch> to the script.

ERROR: architecture is not defined. Accepted values: ia32, intel64

Syntax:
  source mklvars.sh <arch> [MKL_interface] [mod]

   <arch> must be one of the following
       ia32         : Setup for IA-32 architecture
       intel64      : Setup for Intel(R) 64 architecture

   mod (optional) - set path to Intel(R) MKL F95 modules

   MKL_interface (optional) - Intel(R) MKL programming interface for intel64
                              Not applicable without mod
       lp64         : 4 bytes integer (default)
       ilp64        : 8 bytes integer

If the arguments to the sourced script are ignored (consult docs for
your shell) the alternative way to specify target is environment
variables COMPILERVARS_ARCHITECTURE or MKLVARS_ARCHITECTURE to pass
<arch> to the script, MKLVARS_INTERFACE to pass <MKL_interface> and
MKLVARS_MOD to pass <mod>

ERROR: architecture is not defined. Accepted values: ia32, intel64
Syntax: ippvars.sh <arch> [-arch <arch>] [-platform <platform>]

  <arch> must be one of the following:
      ia32           : Set up for IA-32 target.
      intel64        : Set up for Intel(R)64 target.
  <platform> must be of the following:
      linux          : Set to Linux target.
      mac            : Set to Mac target.
      android        : Set to Android target.

If the arguments to the sourced script are ignored (consult docs
for your shell) the alternative way to specify target is environment
variables COMPILERVARS_ARCHITECTURE to pass <arch> to the script
and COMPILERVARS_PLATFORM to pass <platform>
