When I launch the SQL Optimizer either from Toad or as a stand alone, I get the following error:
Unable to load DLL 'T2embed.dll': Access is denied. (Exception from HRESULT: ox80070005 (E_ACCESSDENIED))
Then the program doesn't start. Which is odd because I'm an Administrator on the machine.
Modify the permissions on the t2embed.dll file to READ for EVERYONE and that should allow the user launch SQL Optimizer.
The t2embed.dll file is located in the C:\WINDOWS\system32 folder and/or C:\Windows\SysWOW64
