How to know whether cvirte is installed?

[Lily311]

I want to install cvirte automatically, without user interfere. But how could I know whether cvirte is already installed or not? Since the second installation will uninstall it.

And how to get the version of installed cvirte? From the system registry?

Thanks,

Is there a reason you aren't using a distribution kit? The Build->Create Distribution Kit option will create a distribution kit which handles all of that for you. If you wanted to do it all manually, your best bet would be to research MSI installers, the run time engine is registered normally.

Hi, ryank,

cvirte will be installed alongwith my app which is a VC program. So I never use CVI distribution kit.

And how to research MSI installer? Do you mean the Run-time Engine installation files? I can't find them because all those files are automatically uninstalled before my installation starts.
