Determine path of installation

[niazjkhan]

How do i get the path specified by the user during the installation of the solution?

I believe the path information is stored in Windows installer directory database under TARGETDIR. Now how do i access this TARGETDIR property?

Is there any APIs for access?

Well...where do you need this path? From inside your application? In this case you can just get the application path itself by using 'GetModuleFileName()' as described in this FAQ, assuming that you are Windows...

hey
where you want to get that property???inside any DLL???

then you can use the function:

UINT variable = MsiGetProperty (MSIHANDLE, TEXT("CustomActionData"), your buffer, DWORD cchValueBuf);

dont forget to add [TARGETDIR] in the setup program's corresponding DLL's ->properties->CustomActionData
