Get “IDE failed to start …” message
In some case after to have installed Classic version, you could meet an error when you launch the IDE.
Most of the time the error is introduced because the IDE is not correctly registered.
As suggested by the message we need to execute the \bin\regservers.bat file.
This will initialize correctly the dlls used by the IDE.
In some case, most of the time under 64 bit OS (Win 7 and Win 8), the \bin\regservers.bat generates some errors:
To solve the problem we need to execute the \bin\regservers.bat file via a Command Prompt running as Administrator mode.
Now we can launch the IDE
Attached a video showing the process.
Hope this will help.
