Hello Russ,

You may try following steps to see if it can work:

1. Click Start, and then click Run.
2. Type "MMC.EXE" (without the quotation marks) and click OK.
3. Click Console in the new MMC you created, and then click Add/Remove
Snap-in.
4. In the new window, click Add.
5. Highlight the Certificates snap-in, and then click Add.
6. Choose the Computer, User, or Service Account, options depending on the
certificates you want to view or manage, and click Next.
7. Click OK. (If you choose Computer you will be provided with an option to
open Local Computer or browse for a computer on the network)
8. Click Close, and then click OK.
9. You have now added the Certificates snap-in, which will allow you to  
work with any certificates in your chosen certificate store. You may want
to save this MMC for later use.

Also, please make sure your acocunt is a local adminiatator on the computer
and have full control on local regisrty and files.
