#147 Error in installation

[Anurag Sharma]

Hi
I downloaded the setup.exe file from the following location
http://sourceforge.net/project/showfiles.php?group_id=152364&package_id=170188&release_id=496821

I select new MySQL databse to be created During installtion, .........I get this error message "Invalid class string" on database creation part.
Two things
1. I see that this issue has been reported before and apparently closed.. but I dont find the solution to this issue. Can someone plz tell me how to resolve this issue.
2. when I get the "invalid class string" error during installation, there is no way to close the installer. The X button is disabled, the back button is absent, there is only a "next" button that I can click.... and that throws the error messgae... So you might wanna enable a way to close the installer in error cases like this.

Plz help
