Can one have SolidWorks student version and commercial version installed on same machine?
No, unless you run two boot options.
What if commercial version is uninstalled, SDK is installed and then reverse of it. Will there be any issues later on using commercial version.
If you do a clean uninstall there should be no problem.
Bad thing is that I can't even try before I know the end results.
No, unless you run two boot options.
