Multiple versions of Comctl32.dll loaded

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   We have a user of our product running Windows 7 that loads multiple versions of Comctl32.dll with our application.  An older version of Comctl32 appears to get loaded by the ToolKitPro dll.
The manifest for our app specifies:

<dependency>
    <dependentAssembly>
      <assemblyIdentity type='Win32' name='Microsoft.Windows.Common-Controls' version='6.0.0.0' processorArchitecture='X86' publicKeyToken='6595b64144ccf1df' language='*' />
    </dependentAssembly>
  </dependency>

And there is no manifest entry for the common controls in the ToolkitPro source code.

Using a dependency walker (depends.exe), it shows Comctl32.dll version 6.10.7600.16385 loaded with our app.  But under the ToolkitPro dll tree entry it shows another Comctl32.dll that is version 5.82.7600.16385.  On several other computers, depends.exe does not show Comctl32.dll in the ToolkitPro tree entry.  I beleive this older version is causing an "Parameter is incorrect" error message for the user.

Has anyone seen this behavior?  Or is this an O/S issue?
Any insight to resolving this would be appreciated.
Thanks
