ww.dll installer
 
The ww.dll installer (Install_Siriusware_ww_xxxx.msi) installs ww.dll on a “fresh” system. It creates Program Files\Siriusware and ProgramData\Siriusware directories the same way the other Siriusware installers do as described in the Salesware E-Commerce Installation Guide.
You may need to manually register ww.dll after running the installer. To do this, open a command prompt to the E-Commerce folder and manually register: ww.dll /regserver.
A known issue with installing ww.dll is the following:
Apparently in IIS 7.5+ there are new security settings/features etc.  When you look at the settings for DefaultAppPool in IIS you find that the Identity selected is not NetworkService (which is the old default) but instead ApplicationPoolIdentity.  It is difficult to use the GUI to give permissions to this new IIS account, so you need to do the following:
Right-click on ww.dll and select Properties. Go to the Security tab and select Edit.  Click Add to get to the Select Users or Groups tab.  Make sure that you have Select this object type set to include Built-in security principals, make sure that Location is set to your local computer, and then type the exact text you see below into the object names box:
 
cid:image001.png@01CBE4B9.D716CEF0
 
If you did this correctly, when you click Check Names you see:
 
cid:image002.png@01CBE4B9.D716CEF0
 
After you have found this new, super-top-secret-hard-to-find-through-the-GUI-much-complained-about-in-Internet-posts built in account, click OK and grant it Read and Read & Execute permissions on ww.dll and you are good to go.
The ww.dll file needs to be registered. For complete information on how to install and configure ww.dll, see the Salesware E-Commerce documents. For complete information on how to update ww.dll, see the Updating Salesware Modules document.
 
Note: ww.dll requires the file msvcr71.dll. This file is installed by the Install_Siriusware_CommonFiles_xxxx.msi installer, which is run when you first install Salesware module. Other Microsoft-compatible applications install it as well. If the .dll is not present when you attempt to register ww.dll, you get an error message.
