ADODB. Connection error '800a0e7a'

The error message is as follows:

ADODB. Connection error '800a0e7a'

No provider found. The program may not be correctly installed.

/Hua1/manage/inc/conn. asp, row 8

At first glance, it seems to be a database connection problem, but I read the database connection code repeatedly and there is no error. Next I switch to my own machine to run the website, and the program runs normally, the conclusion is that the website program is normal. The question to be considered next is the machine environment configuration, whether it is a problem with the server software. The local machine is installed with win7 IIS. After carefully reading the IIS configuration, no problem is found. In order to further determine whether the server software is a problem, I plan to change the server software AMPserv 5.2.6 and the results are blocked by anti-virus software. So I am a little angry and don't want to get it. I went back to studying IIs.

You can find the problem at a Glance:

This problem occurs because the system is 64-bit win7. The method is as follows:

Find the IIS application pool, set "Set default properties of the application pool"-> "general"-> "enable 32-bit applications", and set it to True.

In this way, my problem is solved ..
