I had posted earlier today about a decal disappearing problem with my Solidworks 2012. I got a reply telling me that it was a bug with the SP 0, and I had to upgrade to SP 1.0 to get rid of it.
When I tried upgrading to SP1.0 I got the following message about halfway through the installation:
Internal error: The Windows Installer for this product component did not run as expected: 1903.
The log file is attached.
Any ideas what might be causing this?
