Error in EXTRACTKRN_PRE

Hi!

I'm currently upgrading our SAP R/3 Enterprise 4.70 Ext. Set 1.10 to Extension Set 2.00 SR1 in preparation for our MSS requirements.

I keep on getting this error in the <i>Parameter Input</i> module:

ERROR: Extraction of D:\NT\I386\SAPEXE.SAR to directory e:\usr\sap\put\exe failed. Check log file CAR.ECO for error message.

This error occurs during the EXTRACTKRN_PRE phase. I went thru the procedures recommended in <b>SAP Note 741249</b>. Still same error.

Please help.
