Hi,

We are currently testing SolidCP.  Most of our servers are Windows 2012R2 which appear to install and work ok but when trying to install on Windows 2003 (Server ASP.NET v2 component) the install fails with the following showing in the installation log:-

Does anyone have an idea why the install fails?

Thanks
