Hi,

I have web setup project installer program. And windows application. I am calling windows application during installation time by using override Install() function in installer.

In windows application I am executing sql script. Suppose if I run the windows application script is executing in sql server perfectly.

When its working with setup file I am getting the following error.

"Mixed mode assembly is built against version 'v2.0.50727' of the runtime and cannot be loaded in the 4.0 runtime without additional configuration information."

Actuall this error i am getting when i am executing only windows application. So i modified in app.config file as follows:

configuration> <startup uselegacyv2runtimeactivationpolicy="true"> <supportedruntime version="v4.0">

But now when this windows application work with istallation (I mean during installation i am calling windows application) its not working. Its throwing the error as mentioned above

And one more issue: In windows form i have folder browse dialog control and file browse control. If i execut only windows application its working. But in setup file installation times its not working.

Please guide me how to acheive it.

Thanks
