Chipscope 9.2 in XPS

Im trying to include a chipscope core into XPS 9.2 using the Debug configuration screen. When i set up the core and try to update bitstream i get following error:

ERROR:MDT - chipscope_icon_0 (chipscope_icon) - Generating the core : chipscope_icon_0.... Chipscope Core Generator Error : Unable to find the Chipscope Core Generator : generate.exe in the path Registry search for a Chipscope Installation also failed. Please ensure that a valid Chipscope Installation exists for this Chipscope Core to work

Please verify that the MHS Parameters for "chipscope_icon_0" core are valid and the generated Chipscope Core Generator arg file : "implementation/cs_coregen_chipscope_icon_0.arg" is valid ************************************************************* while executing "error "Generating the core : $params(INSTANCE).... Chipscope Core Generator Error : $err

Please verify that the MHS Parameters for \"$params(INSTANC..." (procedure "::hw_chipscope_icon_v1_01_a::icon_generate" line

That is weird, since chipscope is working fine in ISE .. i have tryed to add the chipscope to the registry path but no luck .. what could be that problem ?

Regards
