Hi
I am going to mark this as solved as this is information designed to help anyone running a shop on Windows Server 2008 using IIS 7
If you try to upgrade from version 1.4.x to 1.5.x using the update.php command you may find that you receive a time out, and the upgrade fails “FastCGI process exceeded configured activity timeout in IIS 7”. To overcome this you can run the following scripts in a command window.
To check the current settings use: -
%windir%\system32\inetsrv\appcmd list config -section:system.webServer/fastCgi
To add the activity timeout (assuming CGI location is C:\php\php-cgi.exe): -
%windir%\system32\inetsrv\appcmd set config -section:system.webServer/fastCgi /[fullPath=C:\php\php-cgi.exe].activityTimeout:600
Using this I was able to upgrade my shop with only the Paypal error, however I will do more testing before I try to upgrade my live site.
Hope this helps someone.
Geoff
I forgot to say that this also stops time outs when re indexing your search module
