CertOpenStore Gives Error#5 "Access is denied" for Smartphone application... It's urgent

Hi All,
I am trying to open store in my Smartphone application as follows:
systemStore = CertOpenStore(
CERT_STORE_PROV_SYSTEM,
0,
NULL,
CERT_STORE_ENUM_ARCHIVED_FLAG /*LOWORD*/ |

CERT_SYSTEM_STORE_LOCAL_MACHINE /*HIWORD*/,
_T("ROOT"));

DWORD dwErr = GetLastError();

Here it gives me Error #5 which is "Access is denied.". My application
tries to connect to a remote server which i had given certificate.

My Pocket PC client works well with
systemStore = CertOpenSystemStoreW(NULL, _T("ROOT"));
Here i get a valid handle to the store when i connect to the same
server.

Rest of the things are same in both the cases there is only difference
of API used to open the store.

Can anyone tell me what can be the possible reason behind it.

Thanks in Advance,
Ansh

Anyways friends, i got the solution. I just reinstallled emulator then
it works fine for me. I dont know whats the reason behind it. But if
somebody is facing this prob then reinstalling the emulator should work
for him.

Thnx ,
