Validating Register Key without installing .Net Pre requisities

[Guest]

Hi,

We have an application which is in almost completed stage. We are going
to provide a key for activating the software which is also to be bundled.

We are planned to write the validation in the VB.Net code itself but a
separate simple application. We will install the .Net Pre-requisities in the
system along with our Application package. We are planned to do the
validation before installing the .Net Pre-requisities. We have problem in
validating the key. Suppose consider our customer does not have a .Net being
installed in his systems, he is going to install it in his system. Now the
question is how can we do it using VB.Net or is there no way to run the
VB.Net application before installing Pre-requisities. Are We need to go
through some other langauge which does not need installation like C, ... some
thing like that.

Any solution will be appreciated...

Thanks in advance

VB.NET applications always require the .NET Framework. You may want to use
an application written in C/C++ to check the registry key. The link below
references a sample which demonstrates how to access the registry from
within a C-based application:
