Install the smart card service on Windows 7 and Vista

How to install the smart card service on Windows 7 and Vista

The smart card service is a standard Windows component and it should be present on every system. However, in certain circumstances that is not the case - as a result, programs that depend on this service will fail.

I've previously discussed how to install the smart card service on Windows XP, and I've covered this procedure on Windows 2000. However, I had no solution for Windows Vista and Windows 7.

Fortunately, that is not the case anymore, a solution that works on 32-bit and 64-bit platforms was found, here is how it works.

Sometimes the smart card service is not in the list of services at all, but if you look for the files related to this service (ex: SCardSSP.dll) - they are present in the file system. So the problem is not in the fact that the modules are not there; they are - but they are not loaded.

Having had the opportunity to tinker with a problematic system, I was able to determine that the service is absent because some entries in the registry are different from their "normal system" counterparts.

In other words, the difference is only in the contents of HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\SCardSvr.

If the service is not listed, open regedit and view that key, it will most likely be absent. If it is present - it means that some of its sub-entries are incorrect.

Backup the key (right-click\Export) to a REG file
Delete the key
Download and import this REG file: http://dl.dropbox.com/u/3258602/scard-vistax86x64.reg
Reboot the system

If the planets are aligned properly - the service will be back, and it will be running after the restart. Give your software a try, everything should work. The registry file above works with Vista x86 and Vista x64.

For Windows 7, use this one: http://dl.dropbox.com/u/3258602/scardsvr-win7x64.reg (it should work on both types of platforms).

I hope you'll find this helpful and that you will save all the time I've lost. Feel free to share your experience or ask any questions.

If the sky falls down and Dropbox doesn't work, here is the contents of the files.

Great it works on Windows 7 64 bit. Please note that you need to edit the name of the donloaded file without .txt and than import

Thanks! Worked on Win 7 32 bits!

In my case, the service was working until an automatic windows update. After the update, the service wasn't even listed, but all the files related were present (SCardSvr.dll, etc..).

The only difference between your registry key and mine's, was the mine's was missing this value:

"Start"=dword:00000002

Thanks again for this solution!

Thanks!. It has worked on Windows 7 64 bit. Very grateful for your help. I did not know how to make at all.
