Problem with Forcite

This looks a computer-dependent problem for me. Forcite Module of MS4.3 stopped right after it is getting started. The log file looks like this:

Perl lib version (v5.8.7) doesn't match executable version (v5.8.8) at C:/PROGRA~1/Accelrys/MATERI~1.3/etc/Gateway/perl/lib/Config.pm line 46. Compilation failed in require at C:/PROGRA~1/Accelrys/MATERI~1.3/etc/Gateway/perl/lib/DynaLoader.pm line 25. BEGIN failed--compilation aborted at C:/PROGRA~1/Accelrys/MATERI~1.3/etc/Gateway/perl/lib/DynaLoader.pm line 25. Compilation failed in require at C:/PROGRA~1/Accelrys/MATERI~1.3/etc/Gateway/../../bin/perl/lib/Cfx/COM.pm line 13. BEGIN failed--compilation aborted at C:/PROGRA~1/Accelrys/MATERI~1.3/etc/Gateway/../../bin/perl/lib/Cfx/COM.pm line 13. Compilation failed in require at C:/PROGRA~1/Accelrys/MATERI~1.3/etc/Gateway/../../bin/perl/lib/Cfx/COM/Variant.pm line 4. Compilation failed in require at C:/PROGRA~1/Accelrys/MATERI~1.3/etc/Gateway/../../share/Resources/MatServer/Perl/lib/MatServer.pm line 24.

BEGIN failed--compilation aborted at -e line 7.

However, as I checked the perl coming with MS4.3 is 5.8.7 although my computer does have perl 5.8.8.

The perlrunner.bat is as follows:
@echo off
set DSD_ROOT=C:\PROGRA~1\Accelrys\MATERI~1.3\etc\Gateway\root_default\dsd
set DSD_JOBSROOT=C:\DOCUME~1\ALLUSE~1\APPLIC~1\Accelrys\MATERI~1\4.3\Gateway\root_default\dsd
set CFG_ROOT=C:\DOCUME~1\ALLUSE~1\APPLIC~1\Accelrys\MATERI~1\4.3\Gateway\configurations\default
C:\PROGRA~1\Accelrys\MATERI~1.3\etc\Gateway\perl\bin\perl.exe -IC:\PROGRA~1\Accelrys\MATERI~1.3\etc\Gateway\perl\lib -IC:\PROGRA~1\Accelrys\MATERI~1.3\etc\Gateway\perl\site\lib -IC:\PROGRA~1\Accelrys\MATERI~1.3\etc\Gateway\root_default\dsd\commands C:\DOCUME~1\ALLUSE~1\APPLIC~1\Accelrys\MATERI~1\4.3\Gateway/root_default/dsd/servers/MatServer.pl
So, it only looks for the perl coming with MS4.3.

Any clues?

Thanks in advance.
