dot net framework install

[Iain]

Hi All, not sure if I'm posting in the right place.

I have dot net framework configured as an UI Custom Action to install depending on various properties being set.

The dot net installer starts and unpacks itself but when it attempts to install I receive an error saying 'The windows instalelr service is unavailable. Another application may be running setup.

I'm struggling to understand what's causing this, the only thing running is my project. If this is causing the issue, is there something I need to do to overcome it.

Thanks for any help.

Sorry, forgot to mention I'm using version 6.7.1

Hello,

To overcome this you will need to install the .NET Framework as a global prerequisite.

Thanks for your help.

The trouble is I don't need dot net framework installed on every installation, it depends on actions taken during the installation.

Hello,

In the following thread my colleague describes how you can run a second setup during main installation.

Thanks for your help, I've done this with a pre requisite now
