-------------------------------------------------------------------------------
The information in this article applies to:

- The Source Profiler, included with:
   - Microsoft Visual C++, 32-bit Enterprise Edition, version 6.0 
   - Microsoft Visual C++, 32-bit Professional Edition, version 6.0 
   - Microsoft Visual C++, 32-bit Learning Edition, version 6.0 
-------------------------------------------------------------------------------

SYMPTOMS
========

When using Visual C++ in a Windows NT account other than the one Visual C++ was
installed under, the Profile menu option under the Build menu is disabled.

CAUSE
=====

When Visual C++ is installed, a ProfilerInstalled registry entry is created and
set to true. The Visual C++ installation program places this key under
HKEY_CURRENT_USER. HKEY_CURRENT_USER is specific only to the current user, which
means the registry entry is not being set for other Windows NT accounts.

In earlier versions of Visual C++, installing the profiler is optional.

RESOLUTION
==========

For all accounts to share the ProfilerInstalled registry key, it should be
placed into HKEY_LOCAL_MACHINE instead of HKEY_CURRENT_USER. Add the following
REG_DWORD value to HKEY_LOCAL_MACHINE under the following path:

  Software\Microsoft\DevStudio\6.0\General\ProfilerInstalled = 0x1

STATUS
======

Microsoft has confirmed this to be a bug in the Microsoft products listed at the
beginning of this article.

MORE INFORMATION
================

To easily update the registry:

1. Create a text file on the desktop with any name and a .reg extension.

2. Enter the lines of text below exactly as they appear and include a blank line
  at the bottom of the file.

  REGEDIT4
  [HKEY_LOCAL_MACHINE\Software\Microsoft\DevStudio\6.0\General]
  "ProfilerInstalled"=dword:1

3. Save the file and then double-click the file to merge the entries into the
  registry.

To verify the values have been entered correctly into the registry, you can run
REGEDIT by clicking Run from the Start menu.

In addition, you can also compile and run the following Win32 console
application:

  #include "windows.h"
  #include "stdio.h"

  int main(int argc, char* argv[])
  {
  	HKEY hKey;
  	DWORD dwValue = 1;
  	int nRet = 0;
  	
  	if ( !SUCCEEDED(::RegOpenKeyEx(HKEY_LOCAL_MACHINE, 
  		"Software\\Microsoft\\DevStudio\\6.0\\General",
  		0, KEY_ALL_ACCESS, &hKey)))
  	{
  		printf("Error: Cannot open key\n");
  		return -1;
  	}
  	
  	if ( !SUCCEEDED(::RegSetValueEx(hKey, "ProfilerInstalled",
  		0, REG_DWORD, (unsigned char *)&dwValue, 4)))
  	{
  		printf("Error: Cannot set value\n");
  		nRet = -1;
  	}

  	::RegCloseKey(hKey);
  	
  	return nRet;
  }
