Hi all,

I am trying to write a batch file that checks if .NET 3.5 is installed. I know that running the following command produces the result:

reg query "HKEY_Local_Machine\Software\Microsoft\NET Framework Setup\NDP\v3.5" /v Install

But how can I get hold of the value (0 or 1) and make use of it in an if statement, so that I know whether to install .NET or not?

Many thanks in advance.
Kind regards,

Hi Programm3r,

I'm answering using Ubuntu right now so I couldn't test it right now but what you're looking for is something like:

For /F %%A In ('reg query "HKEY_Local_Machine\Software\Microsoft\NET Framework Setup\NDP\v3.5" /v Install') do goto skip

Echo reg value not found 

goto done

:skip

Echo reg value found 

:done

Good luck!
