we finally upgraded our installshield license and I'm attempting to convert our installs from installshield 5.5 to 2010. I'm now getting errors when making calls to functions in some of our custom .dlls. I've tried several things. I've re written the .dll in both C+ and C#. I tried using the cdecl declaration when defining the prototype, and I've tried it without that.

here is the snippet of install script:

prototype STRING SpInstall.GetOPVersion (STRING);
...
...
...
if ( FindFile ( SUPPORTDIR, "SpInstall.dll", svResult ) = 0 ) then
nResult = UseDLL(szDLLName);
strVersion = GetOPVersion(szDirName);
UnUseDLL(szDLLName);


and here is my dll:

namespace SpInstall
{
public class SpInstall
{
string GetOPVersion(string _DirName)
{
...
}
}
}
attached is the error. any one got any ideas?

I would recommend contacting Flexera and they will help you with working through such issues with an upgraded IS project.
