*I'm not going to fix the Win XP problems, because XP is very old and not may people use it.
I don't have admin rights to my windows box
To install gpvdm normally, the gpvdm installer needs to be run using an account that is allowed to install software to the box. This enalbes the software to be registers by windows, and to assosiate file types to gpvdm. However, some universities/companies disalow this. To get around this, I publish a version of gpvdm that does not have to be installed to run. You can download it here, just follow the instructions and it should work.
If you experience technical problems using gpvdm (i.e. it won't install etc..) please leave a message for me on github here. Or if you prefer drop me an e-mail. I'm very happy to provide help in using gpvdm. There are also a few how to videos dotted around the gpvdm web page that will show you the basics. On the other hand if running simulations is not your thing, I am also more than happy to collaborate with you on modeling data.
