Hi, I have a problem with my SolidWorks ed. 2012-13 student edition, because when I try to install the installation bar rested with message error about or SWRegistration or Error1903: sometimes with one and sometimes with another one because I tried to solve with any kind of solution that I found on the web, I tried also to clean the register keys with CCleaner, because I already installed Solid the last year....but nothing.

I have also tried with batch file on http://www.solidworks.com.cn/sw/support/Tech_Tips/TT_CleanUpdate.html

I hope someone can help me. Thanks

I enclose also the File Log
