System Architect XT is a 32-bit application and requires Microsoft IIS 32-Bit Worker Processes for validating page requests. However, on a 64-bit computer, Microsoft IIS 32-bit worker processes are disabled by default. Enable Microsoft IIS 32-bit worker processes and disable 64-bit worker processes by completing the following steps:
1 Enable 32-bit mode:
cscript %SYSTEMDRIVE%\inetpub\adminscripts\adsutil.vbs SET W3SVC/AppPools/Enable32bitAppOnWin64 1
2 Install the 32-bit version of ASP.NET 2.0 to get the 32-bit worker processes:
3 To allow 32-bit worker processes, set the status of ASP.NET version 2.0.50727 (32-bit) to Allowed.
4 To prohibit 64-bit worker processes, set the status of ASP.NET v2.0.50727 to Prohibited.
Note Steps 3 and 4 are performed in Internet Information Services Manager Web service extension list.
System Architect XT was downgraded from a later version to an earlier version and still contains the registry entries from the later version
1 Uninstall System Architect XT.
2 Clean the.dll and registry entries by using the pathclear.exe file.
3 Manually delete all the folders related to System Architect and System Architect XT.
System Architect XT 11.4.1 is looking for the My Documents folder for the impersonation user. Either this folder does not exist or the current user does not have access to it
On Microsoft Windows 2003 Keep the impersonation user logged in. On Microsoft Windows 2008 Log in as the impersonation user so the directory structure C:\Users\impersonation user.machine_name\Documents is successfully created. The impersonation user can then be logged out.
Two .DLL files were not installed during the System Architect XT installation
This is likely caused by antivirus software running on the server. Turn off the antivirus software, then reinstall System Architect XT. If the antivirus software turns back on (which sometimes occurs every five minutes or so), turn it off as needed until the installation is complete, then turn it back on.
