Win64 - Add/delete SSL Certificate binding prompt error "Parameter is incorrect"

[lmengyew]

Hi,

I am using IWHSysHeaders provided by the IntraWeb library to programmatically add and delete SSL certificate binding at runtime. 

The code works correctly on the Win32 platform; however, on Win64 it returns the error “The parameter is incorrect” when calling 

Code:

HttpSetServiceConfiguration

and

Code:

HttpDeleteServiceConfiguration

I have attached a sample project for your reference. To reproduce the issue, please update the Host, CertStoreName and CertThumbprint values before running the program. 

Could you please advise what might be wrong with my implementation and how this issue can be resolved?
