RegAlyzer comes up with application error

Having problem with completely removing my eTrust Anti Virus software. Can anyone help me with this?

I want to install a brand new AV software, which I purchased recently, since my previous one was just a waste of money. I uninstalled it from Add/remove programs and tried to install my new Symantec AV software. It comes up with an error message.

Based on the message, I decided to remove all the registry entries, which could be a possible hindrance, and installed RegAlyzer on my Win 2000 SP 2 machine.

I installed it and when I tried to remove the registry entries, I got the following error message.

Application Error: The application failed to initialize properly (0xc0000135). Click on OK to terminate the application.

There was no error message while installing the software. I have tried using it on a few other applications and it works well on other PC’s.

Any suggestions would be appreciated.
