The issue about enable 32-bit applications in IIS

Question

Hi everyone,

When I set Enable 32 bit Applications in Application Pool of IIS, I have the following error:

HTTP Error 500.19 - Internal Server Error
The requested page cannot be accessed because the related configuration data for the page is invalid.
There is malformed XML in the applicationhost.config or web.config file.
The server cannot access the applicationhost.config or web.config file because of incorrect NTFS permissions.

Any suggestions would be greatly appreciated!

If you disable enable 32-bit applications and it works, then your problem is running 32-bit applications on a 64-bit computer,

The server cannot access the applicationhost.config or web.config file because of incorrect NTFS permissions.

Please check what are set for Application Pool Identity.
