KBA-01392: IIS 7.0 500.0 Error Reading XML files


This problem is often detected when the BFA workbook (in Microsoft Excel) fails in trying to read its static configuration file. The BFA log will indicate a 500.0 error with the code 0x800700c1. Further investigation reveals that an attempt to read any static XML file causes the same error. Looking at the IIS 7 Failed Request Error Tracing output reveals the following error info:

ModuleName IsapiModule
Notification 128
HttpStatus 500
HttpReason Internal Server Error
HttpSubStatus 0
ErrorCode 2147942593
ErrorCode %1 is not a valid Win32 application. (0x800700c1)


In IIS7, find the application pool and open the Advanced Settings dialog.  Find ‘Enable 32-bit Applications‘ and change the setting to FALSE.  Apply the change.
