The Runtime Error 217 you encountered with installing Vortex occurred under the installation program Inno Setup. This has not happened to any Vortex user before. Moreover Inno Setup is being used by thousands of other people that use it to "Package" their programs into installable exe files (the internet discussions on Runtime Error 217 are ample indication that you are not alone with this problem). We cannot find any evidence that Inno Setup itself might be the problem and we suspect that it is something on your two computers related to Microsoft or your protection system(s).
We are sorry we can not help you any further on this. It's a real pity that you won't be able to use Vortex.
