PROBLEM:
I've tried to start serialXP and got this errormessage immediately:

"The application failed to initialize properly (0xc0000135)"

(Starting serialdotnet gave me the same message)



SOLUTION:
This means that *no* .NET framework is installed.

ooh, yeah, i mentioned that in the wiki, but have given it much mention 
on the forums.  .NET (C#, VB.NET and C++/CLI) are all VERY similar in 
concept to Java.  they basically compile the apps to an intermediate, 
assembler-like language (you can write msil assembly code directly for 
.net, not exactly user friendly!), and this compiles to binary at 
runtime (im sur you know this rooker, but others reading may not).

Vista comes with all 3 versions of the framework, but not XP.

all my apps use the .NET framework 2.0.  i dont think ill switch over to 
3.0 for a long time, im still learning tons with 2.0!
