Hi all...

I've recently purchased Mail Security 6.0.3.201 for the company I am working for and attempting to install it on my Windows Server 2003 64 bit + Exchange 2007 server.

However, after confirming all options and proceeding with the install, a DOS window quickly pops up then out (too quick to see what's displayed), and an error dialog box appears displaying...

"Failed to enable ASP.NET web extensions. Installation will not continue."

and the installer Finishes.

It appears that this error message is unique as I haven't been able to find any articles anywhere.

I've made sure that Active Server pages, ASP.NET 2.050727 are set to allowed in IIS Manager.  No joy!
Here is the content of the SMSMSE60_Setup.log file...

Is there anyone out there that could help me?  I've submitted a case with Symantec Tech Support but they have had to escalate it to a senior engineer!
