Security Problems with FileLogger

[nmnir]

Hi All,

I have an application that runs OK on E51. When I add the FileLogger dll and tried to run it I get "Can't exucute for security reasons" error message.

In my pkg file I have the line
"C:\Symbian\9.2\S60_3rd_FP1\epoc32\release\gcce\urel\FileLogger.dll" -"!:\sys\bin\FileLogger.dll"

And I have the capabilities ReadUserData WriteUserData in the FileLogger mmp file, in my app mmp file and in my cert.

Any Suggestions?

Thanks,
Nahum

Check your application Capability should be same as DLL capability, like if you are using ReadDeviceData only in DLL then ur application should have ReadDeviceData only.

Thanks,

But my app uses more capabilities.

Golden Rule "DLL must have more or at least the same capabilities as the process loading them."

Thanks, but it didn't work.

What didn't work and what exactly is the problem?

Run your application in the emulator and then search for *PlatSec* entries generated by your application in %temp%\epocwind.out, they will tell you which capabilities are needed and why.

I added all the capabilities that my app uses to the mmp of the file logger. Then:
1)abld build gcce urel
2) abld freeze gcce
3) abld build gcce urel

Then on my app:
1) makesis
2) sign sis


I can't run it on the emulatur since it uses APS.

Please reveal the secret and show the contents of your .mmp file for File logger and for your application.

The capab of the file logger are:
SwEvent MultimediaDD NetworkControl NetworkServices ReadDeviceData ReadUserData WriteDeviceData WriteUserData

Capab of my app:
