How to instal two versions of SW on the same computer?

I'm looking for precise information how to install SW2012 on the same machine where my SW2010 is installed. Of course, I need to have both installations functional after installing the new version. OS is Win7 Ultimate x64. My attempt to do it following some instructions found on the internet made my SW2010 unusable and ended with system restore.

This sounds good, although I had an idea to have it on the same drive and once I don't need the older version (once, still in undefined future), just to remove the old version. Creating a new partition sounds ok, even Windows can do that (but I do have a third party software I prefer to use over Windows') and for sure I can install the newer version to another drive, even though it's just intended for data storage (large capacity but slow)...

I'll think about it, and maybe some other suggestions will be posted so I can take those also into consideration and see what will work.

Many claim that they run multiple versions on the same partition without problems, however, no one reveals the secret how did they install the newer not to mess up the older version. Just changing the install directories name from default to "Solidworks 2012" (including the other directories and new toolbox) didn't work for me.

Thanks anyway for the time you took to give me a reasonably simple guidance.

I wouldnt put it on the same C drive, too many conflicts.
I would add a second hard drive to it (if its a desktop) (because its easier then dealing with partitions unless you have a good partition software) and clone the current main drive to it (use Seagate DiscWizard, its free). Then you can choose which drive to boot from when you startup the pc by clicking either F2 or F10 I believe..... just start your pc and look on the screen for which to click.... it flashes up fast to be quick. Remember I would use the second hard drive only to run other programs (SW ver. what ever in this case) and save the files created or changed by it on another drive... this is where it gets complicated. I would remove all files and extra programs from the second drive and only use it to run the other version of SW, the machine then becomes a test box but on the same box. Another advantage of the method is that you primary drive is left intact and if the test box drive doest work out for you just reformat it, no loss.

I have SolidWorks 2011 and 2012 in my C: drive without conflict!
I work with one or the other depending of what to do.
I find out that 2011 work better like it Wrap on curvy solids! 2012 can't do it.

It does not matter if you installed in other patition; because software install under the same Windows system!
Windows 7 Reg. knows it.

((no one reveals the secret how did they install the newer not to mess up the older version.))

How I did... I install 2011 64 bit from the original DVD, This month I install 2012 in the same drive.
I keep the Icons of both in the taskbar, and click the version I want to woth with.
C:\Program Files\SolidWorks Corp\SolidWorks
C:\SolidWorks Data
C:\Program Files\SolidWorks Corp\SolidWorks (2)
C:\SolidWorks Data (2)
C:\Program Files\SolidWorks Corp\SolidWorks eDrawings
C:\Program Files\SolidWorks Corp\SolidWorks eDrawings (2)
C:\Program Files\SolidWorks Corp\SolidWorks Explorer

In the worst case, I can do the system restore again... :)

Do the best for you.

I spend time every time I get new computer, Configured everything the way I need or like.
1) Then Install Acronis True Image and make a image.
2) I have a server home with 4 terabyte, where I save all important data I work.
3) I reach my server from internet anywhere " "
4) In the office we have another server and I connect throuth VPN tunnel.

So you only louse something if you are not interested in your data, or by a computer crash.

You just do! Sorry, no 'precise' information but I guess me being a little geek and having OCD helped. ;)
I put them in separate directories but same driver, named them SolidWorks 2010 and SolidWorks 2011, I don't remember doing anything else that might prevented the issue.
What is the error you're getting?

I let you know if there will ever come one.

I can't tell what the exact problem was, but it was in the registry. Something was messed up and after cleaning it with Registry Workshop and defragmenting it (windows registry) the system boots faster, and I tried to install SW2012 again. Went smoothy and both versions now work fine, no problems with dimension value, I expect everything to work as well from now on...
To be honest, I prefer Linux over Windows, but I need SW for work and no work means no money, and no money means no-no for almost everything else... :/
