Identify if dot.net 4.5 is installed & install it if not

I need to identify if dot.net 4.5 is installed and if it isn't then install it. I can't check to see if the directory is present as it uses the same one as 4.0. I have found that if I put the following in a .bat file it displays the version.

wmic /namespace:\root\cimv2 path win32_product where "name like '%%.NET%%'" get version

but I need to do this in some sort of if statement so that I can then run the exe if it is false.

Can anyone help please?

Bet you it doesn't display the version. This does

wmic /namespace:\\root\cimv2 path win32_product where "name like '%%.NET%%'" get version

Look before the root word.

Then use the Findstr command errorlevel to decide what to do.

(wmic /namespace:\\root\cimv2 path win32_product where "name like '%%.NET%%'" get version|findstr /c:"4.5"
If not errorlevel 1 echo sucess&goto :eof)

Added space before the get (my space key is faulty).

I found this MSDN article.

REG QUERY "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\NET Framework Setup\NDP" /s|FIND " Version"|FIND "4.5."||ECHO Not found! Start setup!

This command will check registry sub keys for "Version" "4.5". You can replace ECHO ... with install command, or GOTO in a batch for further processing..
