I am having errors upgrading from 2009 V4.1 to any higher versions (5.0, 2010 and even 2011).
I receive "code 1601" error. Did not find anything on Solidworks.com. But I did find on the web that is related to the Windows Installer. I downloaded the latest version of Windows Installer and yet I still receive the same error.
The error reads as follows:
"The MSI file C:\documetns and settings\(my name)\My Documents\Solidworks Downloads\Solidworks 2009 SP05.1\swwi\data\English_i386_Solidworks.Msi did not install succesfully. Code=1601"
Another thing I noticed is that under "Add or Remove Programs," SolidWorks does not appear at all.
I run a Windows XP SP3
