[Guest I_Skywalker]

During installing a cab in smartphone, it notify that the cab doesn't have enough system permission. In *.inf , the installing cab needs to modify registry .

How can I solve such problem?

How can I grant enough permission for the installing cab or temply decrease system's secruity level?

Be eager!

Thanks for your kind help.

Assuming you have a well-constructed CAB file, the next thing you should bear in mind is your end-user phone's security level.

Files (cab, exe) not signed with a trusted certificate will not install/run on an application-locked device (ei high security level)

Yeah. Guru!

I tried to sign the cab, including exe&dll, ei, "sign my.cab" , which uses MS default cert. But the problem occurs again.

Why? I have condition to customize Windows Mobile 2005, but not familiar with the app , such as how to sign cab, decrease system secruity level , just as you said, unlock the device

Still even if you have signed the files with SP Dev Code Signing certs, cab or standalone exe will not run on a phone with high security level.

MSDN says...You need to obtain a digital certificate that is trusted by your target phone or phones. The digital certificate has to be trusted to the level of execution privileges you need to run; that is, if you need privileged trust execution, you need to be signed with a privileged certificate. If you only need unprivileged trust execution, you need to be signed with an unprivileged certificate. For most applications, unprivileged trust execution is sufficient.
