Late Breaking Notes and Issues in Internet Explorer 7 Beta 2:
The following open issues in Internet Explorer 7 Beta 2 may be addressed in
Beta updates and in the final release of Internet Explorer 7. We are
mentioning them here because we think they may impact Beta 2 customers. The
information applies to all Microsoft platforms, unless the note specifies
content unique to Windows Vista or Microsoft XP SP2.
a.. SmartBridge -- SmartBridge is distributing an old version of
PSAPI.DLL. As a result, users may receive the following error message after
installation of Internet Explore 7 Beta 2:
SmartBridge Alerts:MotiveSB.exe Entry Point Not Found
The procedure entry point GetProcessImageFileNameW could not be located in
the dynamic link library PSAPI.DLL
To work around this error:
1.. Navigate to the installation location for SmartBridge (\Program
Files\Verizon...\Smart...)
2.. Find PSAPI.DLL and rename it to something like PSAPIOLD.DLL
3.. Reboot the system
The program will find the new PSAPI.DLL in the \Windows\System32 directory
and function normally.
