When you run the "WkRuntime.exe" it extracts the folder in %temp%, in that folder you will get all setup files. set GUI=0 in your setup.ini and run the setup and it will install silently. Cheers.

I have investigated and found the solution to make it silent....

There is one seup.ini file with the setup2.exe.... I have modified the setup.ini file and installed the setup2.exe then it is installing silently....

Thanks for your suggestions....

If you can't be bothered to do the job properly by capturing, have you asked the vendor for help?

this is creating GUID in the uninstall sring  but it is not related to install shield and I am not able to find the msi.
It is haivng uninstall string also which is shown like below:
C:\Program Files\WIBUKEY\Setup\Setup32.exe /R:{00060000-0000-1004-8002-0000C06B5161}

When i check for silent swiches by giving /? , it is giving the informaion like below:

Use: Setup32 Options [SetupIniFileSpec]

The following options can be used:
/R[S]:Guid - removes all VIBU-KEY drivers from the system (only win32),
          S disables user interface.

>>SetupIniFileSpec<< specifies where to search for the setup
configuration file.

I have tried by giving /S still it is not giving...

Can any body help me on this....

Thanks in Advance....

capture it if you cant find silent switches sanjeev. make sure register the drivers using DPInst.exe ( Driver Framework)
