Question: I was in the native environment (64) registered under the COM components successfully and can direct reference in the project, debugging is no problem, but not when I was deployed to the test site, check the event log, prompt can not find the registered class, test site is 64, also is a COM component in the successful registration, but the program to run up to this error, COM components (32)
Analysis: a lot of net friend say it's system problem, don't say 64 registered 32-bit COM component, I feel should not, after all my local machine is 64 but there is no problem, think is likely to be deployed to the IIS process problems, also tried many methods but they are useless, bosses, genuflect is begged support ~ ~

Can you write an exe see references, if can is IIS permissions, IIS default are not allowed to call COM,
