If you convert a project from VC5/6/2002/2003/2005/2008 to VC2010, you will sometimes get an warning during the conversion (UpgradeLog.XML) and during the link phase os your build. This warning might look like:

1>...Microsoft.CppBuild.targets(990,5): warning MSB8012: 
  TargetPath(...LeakFinder_VC9.exe) does not match the Linker's OutputFile property value (...LeakFinder.exe). 
  This may cause your project to build incorrectly. To correct this, please make sure that $(OutDir), $(TargetName) and $(TargetExt) property values match the value specified in %(Link.OutputFile).

or

1>...Microsoft.CppBuild.targets(992,5): warning MSB8012: 
  TargetName(LeakFinder_VC9) does not match the Linker's OutputFile property value (LeakFinder). 
  This may cause your project to build incorrectly. To correct this, please make sure that $(OutDir), $(TargetName) and $(TargetExt) property values match the value specified in %(Link.OutputFile).

The problem is, that the following two settings are not identical (Target Name, Target Extension):

and (Output File):

If you match those two, the warning will be gone 😉

For example, if you have named your EXE in Debug-Builds: “MyAppd.exe” and in Release-Builds “MyApp.exe”, I suggest that your only change the “Target Name” in the General-Page to “MyAppd” (for Debug) and “MyApp” (Release) or ($(ProjectName) if it is the same name as the project).
Then you must also change the “Linker | General | Output File” to the default setting: “” or “$(OutDir)$(TargetName)$(TargetExt)”. This setting is always suggested!

If you want to change the output directory, you should the the “General | Output Directory” setting.

If you have installed VS2008 and/or VS2010 (full), you will notice that OleView is not installed!
The product team decided to remove this utility from the tools-folder.

But you the source-code is still available! You can find it under

C:\\Program Files (x86)\\Microsoft Visual Studio 10.0\\Samples\\1033\\VC2010Samples.zip

Extract the files and build (the release version of)

C++\\MFC\\ole\\oleview\\oleview.sln

Then you have the two files: oleview.exe and iviewers.dll

Also, the same problem is with the OLE-Test Container (tstcon). This application can also be found in the samples.

Here is now the offical statement for the supported runtime OS:

• Windows XP with SP2 and later
• Windows Server 2003 with SP1 and later
• Windows Vista RTM an later
• Windows Server 2008 RTM and later
• Windows 7 and later

This restrictions comes from a security desicion to have a hard dependency on EncodePointer, which is only available in the above OSes.
