When trying to run Web Suite on a 64-bit machine, user needs to create an Application Pool with Classic Mode and set its property to run as 32-bit application. In doing so, user receives this error:
'HTTP Error 503. The service is unavailable'.
Solution: To resolve this issue, please follow these steps:
1. Add ‘preCondition="bitness64"’ to the rpcproxy line in global module file applicationHost.config. By default this file is under C:\Windows\System32\InetSrv\Config\.
2. Open command prompt using Administration Mode and then run this command:
%windir%\system32\inetsrv\appcmd.exe set config -section:system.webServer/httpCompression/-[name='xpress']
3. Also make sure that you have given Network Service Account Read/Write permission to the Setting folder. By default it is under C:\Program Files\BillQuick Web Suite\Web Suite 20xx\public\setting\.
