1. Try deleting your application and associated .PDB file. Then, be sure to
disable INCREMENTAL LINKING. Rebuild your application and see if the

them with a copy of your DLL for further analysis.

But we still get the Error: A reference to dead code was just generated at....
And Purify won't continue pass the Instrumentation Error dialog box.
2- Will try to get IBM Tech Support a copy of the Exe and DLLs. But in the mean time if you have any other suggestion, let us know.

Since you're using the newest version of Purify with a supported version of
Visual Studio on a supported Windows OS --- you're doing everything right.
So the best course of action is to go ahead and contact Tech Support. In the
meantime, you can probably use the -purify-exclude-must option to have Purify
ignore MyApp.dll. This would theoretically allow you to Purify the rest of
the application (minus MyApp.dll). Of course, I'm making this suggestion
without really knowing how important MyApp.dll is to your application. It's
possible that 99% of your code is in that DLL, and in that case, it doesn't
make sense to use -purify-exclude-must. To "exclude" MyApp.dll from being
"fully instrumented", just do the following:
1. Start Purify from the START MENU.
(e.g., Start -> Programs -> IBM Rational -> IBM Rational PurifyPlus -> Purify)
2. Click RUN on the Welcome Screen (if it pops up)
3. Browse to locate your EXE, then hit the SETTINGS... button.
4. Click on the POWERCHECK tab.
5. Click on the CONFIGURE button.
6. Click "CLEAR CACHE" to delete all files in the PurifyPlus cache dir.
7. Click on the FILES tab.
8. Under "Additional Options" enter the following:
