I'm configuring IIS7.5 on a new 64bit server to handle a older website that uses few 32bit components and a MS Access database.
I've set successfully the application pool to support the 32bit - so that Jet4.0 and the old components are working correctly.
However, IIS is working in a odd way: when the application pool is enabled with the 32bit flag, and an error occurs (I tried to induce a division by zero error, therefore a 500 error, and a 404 not found), it doesn't show any error page, but only a totally empty, blank page.
If the 500 error happens, let's say, in the middle of the script execution, the scripts shows its output until the error occurs and then silently stops. The website is configured to use the default IIS error pages, so there is no custom setup for the error pages.
This strange behaviour does not take place if the application pool 32bit is disabled. In this case, everything works normally.
I have made some searchs on google and I've seen that this problem was experienced by other persons but I could not find any solution yet.
