As I loaded up the link to use the HP Quality Center 10, an error message greeted me.
CAPICOM:DLL is not properly installed or registered.
Please install CAPICOM.DLL and restart your browser.
As with other DLLs in Windows XP, some may not have registered properly. I used the following command to re-register the DLL.
By the way, do make sure that capicom.dll is available in that folder. If you don’t have that, you can download from http://www.microsoft.com/en-us/download/details.aspx?id=25281 and install.
After registering the DLL, I could access the site with no problem.
Browser: Microsoft Internet Explorer 6.0
OS: Microsoft Windows XP
Application Involved: HP Quality Center 10.00
