Just checking - did you any other install of SW on this computer - another Student, trial, etc?
If so, you may need to get rid that info first. Not sure - just a guess.
Otherwise I would suggest checking with the University.
I did not have any other version of SW on my computer. I tried downloading it once and it did the same thing, so I deleted the download and the files that it had already unzipped, and I re-downloaded it, but it still did the same thing.
I have just spent the last 4 hours getting the SP 05 update on my computer. What a frustrating mess. Multiple error's and interruptions, never had this problem before with an update. I hope this was a fluke.
or "download failed" or something like that. The installation log has your serial number and contact info in it, so don't post the whole thing online.
The log file will be stored in:
c:\users\<username>\appdata\roaming\SolidWorks\installation logs\<Solidworks Version>\SummaryIMLog_<datecode>.txt
BTW, I looked up your Error Code 403 on the knowledge base and the only things I was able to find were indications that the installation manager itself was being blocked from accessing the download files. From that I think these implications are plausible:
your internet security tools are keeping the installer from accessing the download locations or your internet security software is quarantining files to scan them for malware, preventing the installer from being able to access them. The answer is to disable your security software while you're running the installation. If you want to be sure you're not installing malware, choose the option to download all of the files without running the installer. Then you can scan the files before running Setup.
USER account settings on your computer are preventing you from accessing the the location where the files are being downloaded: Either modify your group policy for the download folder, or choose a download folder to which you have read/write access or run the installation as an administrator.
You have a RAID zero backup configuration and the constant shadow copying is preventing read/write access to the installation files the same way the virus scanner does. Disable your RAID software, along with any real-time backup or ghosting software
