Today I got a new laptop (Windows 7 x64) and I needed to install a lot of software to make my multiple projects work smoothly. After I installed MicroStrategy Desktop and double clicked desktop icon, I got the following error : ActiveX component can't create object
After doing some research, it is easy to fix the issue via the following command lines.
regsvr32 /u regobj.dll
Next time if you have the same issue, this trick should work for you.
