Excellent codecs, but one of the problems I had when installing this on a second PC was that the Real Alternative 2.02 installer would not install the core components.
The reason for this is because I had previously installed realplayer on that PC. Even though realplayer was already uninstalled, the registry entries were still there and blocked 2.02 from installing correctly.
There are two workarounds for this issue:
1. Use a registry cleaner and clean your registry of realplayer entries. I used free windows registry repair from regsoft, and after the 2nd sweep was able to installed 2.02 correctly.
2. The second workaround involves installing the previous version of real alternative (1.9 I believe)
For anyone who is also having this issue, I hope this helps.
