Error: An attempt was made to load a program with an incorrect format. (Exception from HRESULT: 0x8007000B)

When you try to add license in 64-bit OS, you might get the below error:

Error: An attempt was made to load a program with an incorrect format. (Exception from HRESULT: 0x8007000B)

The cause of the error is that the application pool for ITA Standalone is configured to run in 64-bit mode by default. To fix this, please follow:

1.    Find the application pool for ITA Standalone at IIS(7)->Sites->ITAS->Advanced settings:

2.    Then Go to IIS (7)->(PC Name)->Application Pool->ITAS(see above)->Advanced Settings, and you should see that “(General)->Enable 32-bit Application” is “False”:

3.    So we need to change it to “True”, click Ok, then back to add serial code.
