The problem emerges when installing “Visual C++ 2005 Redistributable Package”, the text of the error message is “command line option syntax error.type command /?for help”. After that the installation is shown successfully finished, but ZBrush doesn’t launch.
I’m running WindowsXP. I downloaded a separate install package of Visual C++ and ran it, but it still doesn’t help, the same problem emerged during installation.
Then I searched in google and finally found the solution. I created another user account in Windows and had another try, this time everything went well.
I don’t know what was wrong with my old account, I had to delete it.
What confuses me is that I used to install ZBrush successfully in my old account, about a year ago. Lord knows what happend~~~
Thank you all the same!
