Environment variable SECUDIR under windows

Dear,

we have install the crypto lib due to installation guide

in the sap online help. There it says to put the

environment variable SECUDIR in the registry for window

operting system.

We create a new entry under HKEY_LOCAL_MACHINE->SOFTWARE->SAP-><SID>->Environment.

When starting the whole sap system with mmc the registry

entry is deleted. We try many times and each time the

entry is deleted.

If we check the icm trace file there is a warning that

the envoronment variable SECUDIR does not set.

Does somebody face this problem? Is it correct to set this

variable in the registry of window like stated in the online help or should it set somewhere else?

Thanks,

Ly-Na Phu
